Stark Bank API documentation

Feel free to take a look at our API docs.

Versioning

This project adheres to the following versioning pattern:

Given a version number MAJOR.MINOR.PATCH, increment:

MAJOR version when the API version is incremented. This may include backwards incompatible changes;
MINOR version when breaking changes are introduced OR new functionalities are added in a backwards compatible manner;
PATCH version when backwards compatible bug fixes are implemented.

Setup

1. Install our SDK

1.1 To install the package with gem, run:

gem install starkbank

1.2 Or just add this to your Gemfile:

gem('starkbank', '~> 2.12.0')

2. Create your Private and Public Keys

We use ECDSA. That means you need to generate a secp256k1 private key to sign your requests to our API, and register your public key with us so we can validate those requests.

You can use one of following methods:

2.1. Check out the options in our tutorial.

2.2. Use our SDK:

require('starkbank')

private_key, public_key = StarkBank::Key.create

# or, to also save .pem files in a specific path
private_key, public_key = StarkBank::Key.create('file/keys')

NOTE: When you are creating a new Project, it is recommended that you create the keys inside the infrastructure that will use it, in order to avoid risky internet transmissions of your private-key. Then you can export the public-key alone to the computer where it will be used in the new Project creation.

3. Register your user credentials

You can interact directly with our API using two types of users: Projects and Organizations.

Projects are workspace-specific users, that is, they are bound to the workspaces they are created in. One workspace can have multiple Projects.
Organizations are general users that control your entire organization. They can control all your Workspaces and even create new ones. The Organization is bound to your company's tax ID only. Since this user is unique in your entire organization, only one credential can be linked to it.

3.1. To create a Project in Sandbox:

3.1.1. Log into Starkbank Sandbox

3.1.2. Go to Menu > Integrations

3.1.3. Click on the "New Project" button

3.1.4. Create a Project: Give it a name and upload the public key you created in section 2

3.1.5. After creating the Project, get its Project ID

3.1.6. Use the Project ID and private key to create the object below:

require('starkbank')

# Get your private key from an environment variable or an encrypted database.
# This is only an example of a private key content. You should use your own key.
private_key_content = '
-----BEGIN EC PARAMETERS-----
BgUrgQQACg==
-----END EC PARAMETERS-----
-----BEGIN EC PRIVATE KEY-----
MHQCAQEEIMCwW74H6egQkTiz87WDvLNm7fK/cA+ctA2vg/bbHx3woAcGBSuBBAAK

IF16ZoTVt1FzZ8WkYQ3XomRD4HS13A==
-----END EC PRIVATE KEY-----
'

project = StarkBank::Project.new(
  environment: 'sandbox',
  id: '5656565656565656',
  private_key: private_key_content
)

3.2. To create Organization credentials in Sandbox:

3.2.1. Log into Starkbank Sandbox

3.2.2. Go to Menu > Integrations

3.2.3. Click on the "Organization public key" button

3.2.4. Upload the public key you created in section 2 (only a legal representative of the organization can upload the public key)

3.2.5. Click on your profile picture and then on the "Organization" menu to get the Organization ID

3.2.6. Use the Organization ID and private key to create the object below:

require('starkbank')

# Get your private key from an environment variable or an encrypted database.
# This is only an example of a private key content. You should use your own key.
private_key_content = '
-----BEGIN EC PARAMETERS-----
BgUrgQQACg==
-----END EC PARAMETERS-----
-----BEGIN EC PRIVATE KEY-----
MHQCAQEEIMCwW74H6egQkTiz87WDvLNm7fK/cA+ctA2vg/bbHx3woAcGBSuBBAAK
oUQDQgAE0iaeEHEgr3oTbCfh8U2L+r7zoaeOX964xaAnND5jATGpD/tHec6Oe9U1
IF16ZoTVt1FzZ8WkYQ3XomRD4HS13A==
-----END EC PRIVATE KEY-----
'

organization = StarkBank::Organization.new(
    environment: 'sandbox',
    id: '5656565656565656',
    private_key: private_key_content,
    workspace_id: nil,  # You only need to set the workspace_id when you are operating a specific workspace_id
)

# To dynamically use your organization credentials in a specific workspace_id,
# you can use the Organization.replace() method:
balance = StarkBank::Balance.get(user: StarkBank::Organization.replace(organization, '4848484848484848'))

puts balance

NOTE 1: Never hard-code your private key. Get it from an environment variable or an encrypted database.

NOTE 2: We support 'sandbox' and 'production' as environments.

NOTE 3: The credentials you registered in sandbox do not exist in production and vice versa.

4. Setting up the user

There are three kinds of users that can access our API: Organization, Project and Member.

Project and Organization are designed for integrations and are the ones meant for our SDKs.
Member is the one you use when you log into our webpage with your e-mail.

There are two ways to inform the user to the SDK:

4.1 Passing the user as argument in all functions:

require('starkbank')

balance = StarkBank::Balance.get(user: project) # or organization

4.2 Set it as a default user in the SDK:

require('starkbank')

StarkBank.user = project # or organization

balance = StarkBank::Balance.get()

Just select the way of passing the user that is more convenient to you. On all following examples we will assume a default user has been set.

5. Setting up the error language

The error language can also be set in the same way as the default user:

require('starkbank')

StarkBank.language = 'en-US'

Language options are 'en-US' for english and 'pt-BR' for brazilian portuguese. English is default.

6. Resource listing and manual pagination

Almost all SDK resources provide a query and a page function.

The query function provides a straight forward way to efficiently iterate through all results that match the filters you inform, seamlessly retrieving the next batch of elements from the API only when you reach the end of the current batch. If you are not worried about data volume or processing time, this is the way to go.

require('starkbank')

transactions = StarkBank::Transaction.query(
  after: '2020-01-01',
  before: '2020-03-01'
)

transactions.each do |transaction|
  puts transaction
end

The page function gives you full control over the API pagination. With each function call, you receive up to 100 results and the cursor to retrieve the next batch of elements. This allows you to stop your queries and pick up from where you left off whenever it is convenient. When there are no more elements to be retrieved, the returned cursor will be nil.

require('starkbank')

cursor = nil
transactions = nil
while true
  transactions, cursor = StarkBank::Transaction.page(limit: 5, cursor: cursor)
  transactions.each do |transaction|
    puts transaction
  end
  if cursor.nil?
    break
  end
end

To simplify the following SDK examples, we will only use the query function, but feel free to use page instead.

Testing in Sandbox

Your initial balance is zero. For many operations in Stark Bank, you'll need funds in your account, which can be added to your balance by creating an Invoice or a Boleto.

In the Sandbox environment, most of the created Invoices and Boletos will be automatically paid, so there's nothing else you need to do to add funds to your account. Just create a few Invoices and wait around a bit.

In Production, you (or one of your clients) will need to actually pay this Invoice or Boleto for the value to be credited to your account.

Usage

Here are a few examples on how to use the SDK. If you have any doubts, check out the function or class docstring to get more info or go straight to our [API docs].

Create transactions

To send money between Stark Bank accounts, you can create transactions:

require('starkbank')

transactions = StarkBank::Transaction.create(
  [
    StarkBank::Transaction.new(
      amount: 100, # (R$ 1.00)
      receiver_id: '5083989094170624',
      description: 'Transaction to dear provider',
      external_id: '123456', # so we can block anything you send twice by mistake
      tags: %w[provider]
    ),
    StarkBank::Transaction.new(
      amount: 234, # (R$ 2.34)
      receiver_id: '5083989094170624',
      description: 'Transaction to the other provider',
      external_id: '123457', # so we can block anything you send twice by mistake
      tags: %w[provider]
    )
  ]
)

transactions.each do |transaction|
  puts transaction
end

Note: Instead of using Transaction objects, you can also pass each transaction element in hash format

Query transactions

To understand your balance changes (bank statement), you can query transactions. Note that our system creates transactions for you when you receive boleto payments, pay a bill or make transfers, for example.

require('starkbank')

transactions = StarkBank::Transaction.query(
  after: '2020-01-01',
  before: '2020-03-01'
)

transactions.each do |transaction|
  puts transaction
end

Get transaction

You can get a specific transaction by its id:

require('starkbank')

transaction = StarkBank::Transaction.get('5764045667827712')

puts transaction

Get balance

To know how much money you have in your workspace, run:

require('starkbank')

balance = StarkBank::Balance.get()

puts balance

Create transfers

You can also create transfers in the SDK (TED/Pix) and configure transfer behavior according to its rules.

require('starkbank')

transfers = StarkBank::Transfer.create(
  [
    StarkBank::Transfer.new(
      amount: 100,
      bank_code: '033', # TED
      branch_code: '0001',
      account_number: '10000-0',
      tax_id: '012.345.678-90',
      name: 'Tony Stark',
      tags: %w[iron suit]
    ),
    StarkBank::Transfer.new(
      amount: 200,
      bank_code: '20018183', # Pix
      branch_code: '1234',
      account_number: '123456-7',
      account_type: 'salary',
      external_id: 'my-internal-id-12345',
      tax_id: '012.345.678-90',
      name: 'Jon Snow',
      scheduled: Time.now + 24 * 3600,
      tags: [],
      rules: [
        StarkBank::Transfer::Rule.new(
          key: 'resendingLimit',    # Set maximum number of retries if Transfer fails due to systemic issues at the receiver bank
          value: 5                  # Our resending limit is 10 by default
      ]
    )
  ]
)

transfers.each do |transfer|
  puts transfer
end

Note: Instead of using Transfer objects, you can also pass each transfer element in hash format

Query transfers

You can query multiple transfers according to filters.

require('starkbank')

transfers = StarkBank::Transfer.query(
  after: '2020-01-01',
  before: '2020-04-01'
)

transfers.each do |transfer|
  puts transfer.name
end

Get a transfer

To get a single transfer by its id, run:

require('starkbank')

transfer = StarkBank::Transfer.get('4804196796727296')

puts transfer

Cancel a scheduled transfer

To cancel a single scheduled transfer by its id, run:

require('starkbank')

transfer = StarkBank::Transfer.delete('4804196796727296')

puts transfer

Get a transfer PDF

A transfer PDF may also be retrieved by passing its id. This operation is only valid if the transfer status is "processing" or "success".

require('starkbank')

pdf = StarkBank::Transfer.pdf('4832343898456064')

File.binwrite('transfer.pdf', pdf)

Be careful not to accidentally enforce any encoding on the raw pdf content, as it may yield abnormal results in the final file, such as missing images and strange characters.

Query transfer logs

You can query transfer logs to better understand transfer life cycles.

require('starkbank')

logs = StarkBank::Transfer::Log.query(limit: 50)

logs.each do |log|
  puts log
end

Get a transfer log

You can also get a specific log by its id.

require('starkbank')

log = StarkBank::Transfer::Log.get('5554732936462336')

puts log

Get DICT key

You can get the Pix key's parameters by its id.

require('starkbank')

dict_key = StarkBank::DictKey.get('tony@starkbank.com')

puts dict_key

Query your DICT keys

To take a look at the Pix keys linked to your workspace, just run the following:

require('starkbank')

dict_keys = StarkBank::DictKey.query(
  status: 'registered',
  type: 'evp'
  limit: 10
)

dict_keys.each do |dict_key|
  puts dict_key
end

Query Bacen institutions

You can query institutions registered by the Brazilian Central Bank for Pix and TED transactions.

require('starkbank')

institutions = StarkBank::Institution.query(search: 'stark').to_a

institutions.each do |institution|
  puts institution
end

Create invoices

You can create dynamic QR Code invoices to charge customers or to receive money from accounts you have in other banks.

Since the banking system only understands value modifiers (discounts, fines and interest) when dealing with dates (instead of datetimes), these values will only show up in the end user banking interface if you use dates in the "due" and "discounts" fields.

If you use datetimes instead, our system will apply the value modifiers in the same manner, but the end user will only see the final value to be paid on his interface.

Also, other banks will most likely only allow payment scheduling on invoices defined with dates instead of datetimes.

require('starkbank')

invoices = StarkBank::Invoice.create(
  [
    StarkBank::Invoice.new(
      amount: 23571,  # R$ 235,71 
      name: 'Buzz Aldrin',
      tax_id: '012.345.678-90', 
      due: Time.now + 24 * 3600,
      fine: 5,  # 5%
      interest: 2.5  # 2.5% per month
    )
  ]
)

invoices.each do |invoice|
  puts invoice
end

Note: Instead of using Invoice objects, you can also pass each invoice element in hash format

Get an invoice

After its creation, information on an invoice may be retrieved by passing its id. Its status indicates whether it's been paid.

require('starkbank')

invoice = StarkBank::Invoice.get('6365512502083584')

puts invoice

Get an invoice QR Code

After its creation, an invoice QR Code png may be retrieved by passing its id.

require('starkbank')

png = StarkBank::Invoice.qrcode('6365512502083584')

File.binwrite('qrcode.png', png)

Be careful not to accidentally enforce any encoding on the raw png content, as it may yield abnormal results in the final file, such as missing images and strange characters.

Get an invoice PDF

After its creation, an invoice PDF may be retrieved by passing its id.

require('starkbank')

pdf = StarkBank::Invoice.pdf('6365512502083584', layout: 'default')

File.binwrite('invoice.pdf', pdf)

Be careful not to accidentally enforce any encoding on the raw pdf content, as it may yield abnormal results in the final file, such as missing images and strange characters.

Cancel an invoice

You can also cancel an invoice by its id. Note that this is not possible if it has been paid already.

require('starkbank')

invoice = StarkBank::Invoice.update('5155165527080960', status: 'canceled')

puts invoice

Update an invoice

You can update an invoice's amount, due date and expiration by its id. Note that this is not possible if it has been paid already.

require('starkbank')
require('date')

invoice = StarkBank::Invoice.update(
  '5155165527080960',
  amount: 100,
  expiration: 7200,  # 2 hours
  due: Time.now + 3600
)

puts invoice

Query invoices

You can get a list of created invoices given some filters.

require('starkbank')
require('date')

invoices = StarkBank::Invoice.query(
  after: '2020-01-01',
  before: Date.today - 1
)

invoices.each do |invoice|
  puts invoice
end

Query invoice logs

Logs are pretty important to understand the life cycle of an invoice.

require('starkbank')

logs = StarkBank::Invoice::Log.query(limit: 150)

logs.each do |log|
  puts log
end

Get an invoice log

You can get a single log by its id.

require('starkbank')

log = StarkBank::Invoice::Log.get('5155165527080960')

puts log

Get a reversed invoice log PDF

Whenever an Invoice is successfully reversed, a reversed log will be created. To retrieve a specific reversal receipt, you can request the corresponding log PDF:

require('starkbank')

pdf = StarkBank::Invoice::Log.pdf('5155165527080960')
File.binwrite('invoice_log.pdf', pdf)

Be careful not to accidentally enforce any encoding on the raw pdf content, as it may yield abnormal results in the final file, such as missing images and strange characters.

Get an invoice payment information

Once an invoice has been paid, you can get the payment information using the InvoicePayment sub-resource:

require('starkbank')

payment = StarkBank::Invoice.payment('5155165527080960');

puts payment

Create DynamicBrcodes

You can create simplified dynamic QR Codes to receive money using Pix transactions. When a DynamicBrcode is paid, a Deposit is created with the tags parameter containing the character “dynamic-brcode/” followed by the DynamicBrcode’s uuid "dynamic-brcode/{uuid}" for conciliation.

The differences between an Invoice and the DynamicBrcode are the following:

	Invoice	DynamicBrcode
Expiration	✓	✓
Can only be paid once	✓	✓
Due, fine and fee	✓	X
Discount	✓	X
Description	✓	X
Can be updated	✓	X

Note: In order to check if a BR code has expired, you must first calculate its expiration date (add the expiration to the creation date). Note: To know if the BR code has been paid, you need to query your Deposits by the tag "dynamic-brcode/{uuid}" to check if it has been paid.

require('starkbank')

brcodes = StarkBank::DynamicBrcode.create([
    StarkBank::DynamicBrcode.new(
      amount: 23571,  # R$ 235,71 
      expiration: 3600 * 3
    ),
    StarkBank::DynamicBrcode(
      amount: 23571,  # R$ 235,71 
      expiration: 3600 * 3
    )
])

brcodes.each do |brcode|
  puts brcode
end

Note: Instead of using DynamicBrcode objects, you can also pass each brcode element in dictionary format

Get a DynamicBrcode

After its creation, information on a DynamicBrcode may be retrieved by its uuid.

require('starkbank')

brcode = StarkBank::DynamicBrcode.get("bb9cd43ea6f4403391bf7ef6aa876600")

puts brcode

Query DynamicBrcodes

You can get a list of created DynamicBrcodes given some filters.

require('starkbank')

brcodes = StarkBank::DynamicBrcode.query(
    after: "2023-01-01",
    before: "2023-03-01"
)

brcodes.each do |brcode|
  puts brcode
end

Query deposits

You can get a list of created deposits given some filters.

require('starkbank')
require('date')

deposits = StarkBank::Deposit.query(
  after: '2020-01-01',
  before: Date.today - 1
)

deposits.each do |deposit|
  puts deposit
end

Get a deposit

After its creation, information on a deposit may be retrieved by its id.

require('starkbank')

deposit = StarkBank::Deposit.get('6365512502083584')

puts deposit

Update a deposit

You can update an deposit's amount by its id. Only the amount can be decreased, which will result in a payment reversal. To fully reverse the deposit, pass amount = 0.

require('starkbank')

deposit = StarkBank::Deposit.update(
  '5155165527080960',
  amount: 0,
)

puts deposit

Query deposit logs

Logs are pretty important to understand the life cycle of a deposit.

require('starkbank')

logs = StarkBank::Deposit::Log.query(limit: 150)

logs.each do |log|
  puts log
end

Get a deposit log

You can get a single log by its id.

require('starkbank')

log = StarkBank::Invoice::Log.get('5155165527080960')

puts log

Create boletos

You can create boletos to charge customers or to receive money from accounts you have in other banks.

require('starkbank')

boletos = StarkBank::Boleto.create(
  [
    StarkBank::Boleto.new(
      amount: 23571,  # R 235,71 
      name: 'Buzz Aldrin',
      tax_id: '012.345.678-90', 
      street_line_1: 'Av. Paulista, 200', 
      street_line_2: '10 andar',
      district: 'Bela Vista', 
      city: 'São Paulo',
      state_code: 'SP',
      zip_code: '01310-000',
      due: Time.now + 24 * 3600,
      fine: 5,  # 5%
      interest: 2.5  # 2.5% per month
    )
  ]
)

boletos.each do |boleto|
  puts boleto
end

Note: Instead of using Boleto objects, you can also pass each boleto element in hash format

Get a boleto

After its creation, information on a boleto may be retrieved by passing its id. Its status indicates whether it's been paid.

require('starkbank')

boleto = StarkBank::Boleto.get('6365512502083584')

puts boleto

Get a boleto PDF

After its creation, a boleto PDF may be retrieved by passing its id.

require('starkbank')

pdf = StarkBank::Boleto.pdf('6365512502083584', layout: 'default')

File.binwrite('boleto.pdf', pdf)

Be careful not to accidentally enforce any encoding on the raw pdf content, as it may yield abnormal results in the final file, such as missing images and strange characters.

Delete a boleto

You can also cancel a boleto by its id. Note that this is not possible if it has been processed already.

require('starkbank')

boleto = StarkBank::Boleto.delete('5155165527080960')

puts boleto

Query boletos

You can get a list of created boletos given some filters.

require('starkbank')

end

Get a boleto log

You can get a single log by its id.

require('starkbank')

log = StarkBank::Boleto::Log.get('5155165527080960')

puts log

Investigate a boleto

You can discover if a StarkBank boleto has been recently paid before we receive the response on the next day. This can be done by creating a BoletoHolmes object, which fetches the updated status of the corresponding Boleto object according to CIP to check, for example, whether it is still payable or not. The investigation happens asynchronously and the most common way to retrieve the results is to register a 'boleto-holmes' webhook subscription, although polling is also possible.

require('starkbank')
holmes = StarkBank::BoletoHolmes.create([
  StarkBank::BoletoHolmes.new(
    boleto_id: '5656565656565656'
  ),
  StarkBank::BoletoHolmes.new(
    boleto_id: '4848484848484848'
  )
])

holmes.each do |sherlock|
  puts sherlock
end

Note: Instead of using BoletoHolmes objects, you can also pass each payment element in hash format

Get a boleto holmes

To get a single Holmes by its id, run:

require('starkbank')
sherlock = StarkBank::BoletoHolmes.get('19278361897236187236')

puts sherlock

Query boleto holmes

You can search for boleto Holmes using filters.

require('starkbank')
holmes = StarkBank::BoletoHolmes.query(limit: 10, status: 'solved', before: DateTime.now).to_a

holmes.each do |sherlock|
  puts sherlock
end

Query boleto holmes logs

Searches are also possible with boleto holmes logs:

require('starkbank')
logs = StarkBank::BoletoHolmes::Log.query(limit: 10, types: 'solved').to_a

logs.each do |log|
  puts log
end

Get a boleto holmes log

You can also get a boleto holmes log by specifying its id.

require('starkbank')
log = StarkBank::BoletoHolmes::Log.get('5155165527080960')

puts webhook

Delete a webhook

You can also delete a specific webhook by its id.

require('starkbank')

webhook = StarkBank::Webhook.delete('10827361982368179')

puts webhook

Process webhook events

It's easy to process events that arrived in your webhook. Remember to pass the signature header so the SDK can make sure it's really StarkBank that sent you the event.

require('starkbank')

request = listen()  # this is the method you made to get the events posted to your webhook

event = StarkBank::Event.parse(content: request.body.read, signature: request.headers['Digital-Signature'])

if event.subscription == 'transfer'
  puts event.log.transfer
elsif event.subscription == 'deposit'
  puts event.log.deposit
elsif event.subscription == 'invoice'
  puts event.log.invoice
elsif event.subscription == 'brcode-payment'
  puts event.log.payment
elsif event.subscription == 'boleto'
  puts event.log.boleto
elsif event.subscription == 'boleto-payment'
  puts event.log.payment
elsif event.subscription == 'utility-payment'
  puts event.log.payment
end

Query webhook events

To search for webhook events, run:

require('starkbank')

events = StarkBank::Event.query(after: '2020-03-20', is_delivered: false)

events.each do |event|
  puts event
end

Get a webhook event

You can get a specific webhook event by its id.

require('starkbank')

event = StarkBank::Event.get('4828869076975616')

puts event

Delete a webhook event

You can also delete a specific webhook event by its id.

require('starkbank')

event = StarkBank::Event.delete('4828869076975616')

puts event

Set webhook events as delivered

This can be used in case you've lost events. With this function, you can manually set events retrieved from the API as "delivered" to help future event queries with is_delivered: false.

require('starkbank')

event = StarkBank::Event.update('5892075044208640', is_delivered: true)

puts event

Query failed webhook event delivery attempts information

You can also get information on failed webhook event delivery attempts.

require('starkbank')

attempts = StarkBank::Event::Attempt.query(after: '2020-03-20').to_a;

attempts.each do |attempt|
  puts attempt
end

Get a failed webhook event delivery attempt information

To retrieve information on a single attempt, use the following function:

require('starkbank')

attempt = StarkBank::Event::Attempt.get('1616161616161616')

puts attempt

Create a new Workspace

The Organization user allows you to create new Workspaces (bank accounts) under your organization. Workspaces have independent balances, statements, operations and users. The only link between your Workspaces is the Organization that controls them.

Note: This route will only work if the Organization user is used with workspace_id=nil.

require('starkbank')

workspace = StarkBank::Workspace.create(
    username: 'iron-bank-workspace-1',
    name: 'Iron Bank Workspace 1',
    user: organization,
)

puts workspace

List your Workspaces

This route lists Workspaces. If no parameter is passed, all the workspaces the user has access to will be listed, but you can also find other Workspaces by searching for their usernames or IDs directly.

require('starkbank')

workspaces = StarkBank::Workspace.query(limit: 30)

workspaces.each do |workspace|
  puts workspace
end

Get a Workspace

You can get a specific Workspace by its id.

require('starkbank')

workspace = StarkBank.Workspace.get('10827361982368179')

puts workspace

Update a Workspace

You can update a specific Workspace by its id.

require('starkbank')

picture = open("path/to/picture.png", "rb").read()

updatedWorkspace = StarkBank::Workspace.update(
  workspace.ID, 
  username: 'new-username-test', 
  name: 'Updated workspace test', 
  allowed_tax_ids: ['20.018.183/0001-80'],
  picture: picture,
  picture_type: "image/png"
)

puts updatedWorkspace

You can also block a specific Workspace by its id.

require('starkbank')

updatedWorkspace = StarkBank::Workspace.update(
  workspace.ID, 
  status: "blocked",
  user:starkbank.Organization.replace(organization, workspace.ID)
)

puts updatedWorkspace

Request

This resource allows you to send HTTP requests to StarkBank routes.

GET

You can perform a GET request to any StarkBank route.

It's possible to get a single resource using its id in the path.

require('starkbank')

example_id = "5155165527080960"
request = StarkBank::Request.get(
    path:"/invoice/#{example_id}"
).json

puts request

You can also get the specific resource log,

require('starkbank')

example_id = "5699165527090460"
request = StarkBank::Request.get(
    path:"/invoice/log/#{example_id}",
).json

puts request

This same method will be used to list all created items for the requested resource.

require('starkbank')

request = StarkBank::Request.get(
    path:"/invoice",
    query:{"limit": 10, "status": "paid"},
).json

puts request

To list logs, you will use the same logic as for getting a single log.

require('starkbank')

request = StarkBank::Request.get(
    path:"/invoice/log",
    query:{"limit": 10, "status": "paid"},
).json

puts request

You can get a resource file using this method.

require('starkbank')

example_id = "5155165527080960"
pdf = StarkBank::Request.get(
    path:"/invoice/#{example_id}/pdf",
).content
File.binwrite('invoice.pdf', pdf)

POST

You can perform a POST request to any StarkBank route.

This will create an object for each item sent in your request

Note: It's not possible to create multiple resources simultaneously. You need to send separate requests if you want to create multiple resources, such as invoices and boletos.

require('starkbank')

data={
    "invoices": [
        {
            "amount": 100,
            "name": "Iron Bank S.A.",
            "taxId": "20.018.183/0001-80"
        },
        {
            "amount": 450000,
            "name": "Arya Stark.",
            "taxId": "012.345.678-90"
        }
    ]
}
request = StarkBank::Request.get(
    path:"/invoice",
    body:data
).json
puts request

PATCH

You can perform a PATCH request to any StarkBank route.

It's possible to update a single item of a StarkBank resource.

require('starkbank')

example_id = "5155165527080960"
request = StarkBank::Request.patch(
    path:"/invoice/#{example_id}",
    body:{"amount": 0},
).json
puts request

PUT

You can perform a PUT request to any StarkBank route.

It's possible to put a single item of a StarkBank resource.

require('starkbank')

data = {
    "profiles": [
        {
            "interval": "day",
            "delay": 0
        }
    ]
}
request = StarkBank::Request.put(
    path:"/split-profile",
    body:data,
).json
puts request

DELETE

You can perform a DELETE request to any StarkBank route.

It's possible to delete items of StarkBank resource.

require('starkbank')

example_id = "5155165527080960"
request = StarkBank::Request.delete(
    path:"/transfer/#{example_id}",
).json
puts request

Handling errors

The SDK may raise one of four types of errors: InputErrors, InternalServerError, UnknownError, InvalidSignatureError

InputErrors will be raised whenever the API detects an error in your request (status code 400). If you catch such an error, you can get its elements to verify each of the individual errors that were detected in your request by the API. For example:

require('starkbank')

begin
  transactions = StarkBank::Transaction.create(
    [
      StarkBank::Transaction.new(
        amount: 99999999999999,
        receiver_id: '1029378109327810',
        description: '.',
        external_id: '12345',
        tags: %w[provider]
      )
    ]
  )
rescue StarkBank::Error::InputErrors => e
  e.errors.each do |error|
    puts error.code
    puts error.message
  end
end

InternalServerError will be raised if the API runs into an internal error. If you ever stumble upon this one, rest assured that the development team is already rushing in to fix the mistake and get you back up to speed.

UnknownError will be raised if a request encounters an error that is neither InputErrors nor an InternalServerError, such as connectivity problems.

InvalidSignatureError will be raised specifically by StarkBank::Event.parse() when the provided content and signature do not check out with the Stark Bank public key.
