Microsoft Teams Incoming Webhook Ruby

Ruby gem for integration with Microsoft Teams Incoming Webhook.

Installation

Add this line to your application's Gemfile:

gem 'microsoft_teams_incoming_webhook_ruby'

And then execute:

bundle install

Or install it yourself as:

gem install microsoft_teams_incoming_webhook_ruby

Usage

Configuration of Incoming Webhook connector on your Teams channels

The first step before using this gem is to configure the connector inside your Teams channels.

For this purpose, please check the official documentation from Microsoft. It's listed below some useful links:

https://docs.microsoft.com/en-us/microsoftteams/platform/webhooks-and-connectors/how-to/add-incoming-webhook
https://techcommunity.microsoft.com/t5/microsoft-365-pnp-blog/how-to-configure-and-use-incoming-webhooks-in-microsoft-teams/ba-p/2051118
https://www.youtube.com/watch?v=amvh4rzTCS0

After the configuration, keep your generated Incoming Webhook URL in a secret and secure way.

You will use it (the URL) in next sections of README.

Hello World message sending

Once you have configured Incoming Webhook inside your Teams channels, you can send a very simple Hello World message:

require 'microsoft_teams_incoming_webhook_ruby'

message = MicrosoftTeamsIncomingWebhookRuby::Message.new do |m|
  m.url = 'YOUR INCOMING WEBHOOK URL HERE'
  m.text = 'Hello World!'
end

message.send

Note that there are 2 keys that is the minimum required to define a valid message for Teams:

url: The URL of Incoming Webhook connector, generated via Microsoft Teams
text: The text of your message

There are many other possible keys to be sent to Microsoft Incoming Webhook API. But pay attention to always send at least the 2 keys.

Gem public interface

The MicrosoftTeamsIncomingWebhookRuby::Message class has 3 main methods:

new: Initialization of object. You need to pass a block as parameter, containing the message structure. This structure will be converted automatically to JSON and be sent to Microsoft Incoming Webhook API.
builder: Message builder object, that allows add/redefine/remove fields arbitrarily.
send: Invocation of Incoming Webhook API, using HTTPS.

Message structure

The Microsoft Incoming Webhook API allows us to send a variety of fields, that will result in diferents cards displayed in Teams channels.

Because of this, the gem will not enforce any schema in message structure. The only required parameters are url and text. Any other options will be accepted, considering that Microsoft Incoming Webhook API accepts it.

The message structure and its fields can be defined in two moments:

Initialization of MicrosoftTeamsIncomingWebhookRuby::Message object
After object initialization, but before send method call

🚨 You can add/replace/remove any fields arbitrarily, but keeping at least the minimum required fields (url and text). Otherwise, an error will be generated when invoke send method.

Below there are some examples of this manipulation:

Initialization of attributes in MicrosoftTeamsIncomingWebhookRuby::Message object

require 'microsoft_teams_incoming_webhook_ruby'

message = MicrosoftTeamsIncomingWebhookRuby::Message.new do |m|
  m.url = 'YOUR INCOMING WEBHOOK URL HERE'
  m.text = 'Hello World!'
  m.my_arbitrary_field = 'My value'
  m.my_another_arbitrary_field = { my: 'value' }
end

message.send

Addition of attribute after object initialization, but before send method call

require 'microsoft_teams_incoming_webhook_ruby'

message = MicrosoftTeamsIncomingWebhookRuby::Message.new do |m|
  m.url = 'YOUR INCOMING WEBHOOK URL HERE'
  m.text = 'Hello World!'
end

message.builder.my_arbitrary_field = 'My value'
message.builder.my_another_arbitrary_field = { my: 'value' }

message.send

Remotion of attributes after object initialization, but before send method call

require 'microsoft_teams_incoming_webhook_ruby'

message = MicrosoftTeamsIncomingWebhookRuby::Message.new do |m|
  m.url = 'YOUR INCOMING WEBHOOK URL HERE'
  m.text = 'Hello World!'
  m.my_custom_field = 'My custom value'
end

message.builder.delete_field :my_custom_field

message.send

Redefinition of attributes after object initialization, but before send method call

require 'microsoft_teams_incoming_webhook_ruby'

message = MicrosoftTeamsIncomingWebhookRuby::Message.new do |m|
  m.url = 'YOUR INCOMING WEBHOOK URL HERE'
  m.text = 'Hello World!'
  m.my_custom_field = 'My custom value'
end

message.builder.my_custom_field = 'Updated value'

message.send

In case of keys that starts with @, it is necessary to use brackets notation:

require 'microsoft_teams_incoming_webhook_ruby'

message = MicrosoftTeamsIncomingWebhookRuby::Message.new do |m|
  m.url = 'YOUR INCOMING WEBHOOK URL HERE'
  m.text = 'Hello World!'
  m['@my_field'] = 'Lorem ipsum'
end

message.builder['@my_another_new_field'] = 'Ipsum valorium'

message.send

Error handling

If the builder object turn itself invalid before invocation of send method, the gem will raise a MicrosoftTeamsIncomingWebhookRuby::Message::Error::InvalidMessage exception:

require 'microsoft_teams_incoming_webhook_ruby'

message = MicrosoftTeamsIncomingWebhookRuby::Message.new do |m|
  m.url = 'YOUR INCOMING WEBHOOK URL HERE'
  m.text = 'Hello World!'
end

message.builder.delete_field :url

begin
  message.send
rescue MicrosoftTeamsIncomingWebhookRuby::Message::Error::InvalidMessage
  puts 'Your message structure is invalid!'
end

require 'microsoft_teams_incoming_webhook_ruby'

begin
  message = MicrosoftTeamsIncomingWebhookRuby::Message.new do |m|
    m.my_only_one_field = 'Lorem ipsum'
  end
rescue MicrosoftTeamsIncomingWebhookRuby::Message::Error::InvalidMessage
  puts 'Your message structure is invalid'
end

If a non-successful response code be returned by API (1xx, 4xx or 5xx), the gem will raise a MicrosoftTeamsIncomingWebhookRuby::Message::Error::FailedRequest exception:

require 'microsoft_teams_incoming_webhook_ruby'

message = MicrosoftTeamsIncomingWebhookRuby::Message.new do |m|
  m.url = 'YOUR INCOMING WEBHOOK URL HERE'
  m.text = 'My message'
end

begin
  message.send
rescue MicrosoftTeamsIncomingWebhookRuby::Message::Error::FailedRequest
  puts 'Microsoft API is down, broken, or your network failed!'
end
