Customerio

A node client for the Customer.io REST API.

Installation

npm i --save customerio-node

Usage

Creating a new instance

In order to start using the library, you first need to create an instance of the CIO class:

let CIO = require('customerio-node');
const cio = new CIO(siteId, apiKey, [defaults]);

Both the siteId and apiKey are required in order to create a Basic Authorization header, allowing us to associate the data with your account.

Optionally you may pass defaults as an object that will be passed to the underlying request instance. A list of the possible options are listed here.

This is useful to override the default 10s timeout. Example:

const cio = new CIO(123, 'abc', {
  timeout: 5000
});

---

cio.identify(id, data)

Creating a person is as simple as identifying them with this call. You can also use this method to update a persons data.

cio.identify(1, {
  email: '[email protected]',
  created_at: 1361205308,
  first_name: 'Bob',
  plan: 'basic'
});

Options

• id: String (required)
• data: Object (optional)
  • email is a required key if you intend to send email messages
  • created_at is a required key if you want to segment based on signed up/created date

---

cio.destroy(id)

This will delete a person from Customer.io.

cio.destroy(1);

Options

• id: String (required)

---

cio.track(id, data)

The track method will trigger events within Customer.io. When sending data along with your event, it is required to send a name key/value pair in you data object.

Simple event tracking

cio.track(1, { name: 'updated' });

Sending data with an event

cio.track(1, {
  name: 'purchase',
  data: {
    price: '23.45',
    product: 'socks'
  }
});

Options

• id: String (requiredl)
• data: Object (required)
  • name is a required key on the Object
  • data is an optional key for additional data sent over with the event

---

cio.trackAnonymous(data)

Anonymous event tracking does not require a customer ID and these events will not be associated with a tracked profile in Customer.io

cio.trackAnonymous({
  name: 'updated',
  data: {
    updated: true,
    plan: 'free'
  }
});

Options

• data: Object (required)
  • name is a required key on the Object
  • data is an optional key for additional data sent over with the event

---

cio.trackPageView(id, url)

Sending a page event includes sending over the customers id and the name of the page.

cio.trackPageView(1, '/home');

Options

• id: String (required)
• url: String (required)

cio.triggerBroadcast(campaign_id, data, recipients)

Trigger an email broadcast using the email campaign's id. You can also optionally pass along custom data that will be merged with the liquid template, and additional conditions to filter recipients.

cio.triggerBroadcast(1, { name: 'foo'}, { segment: { id: 7 }});

You can also use emails or ids to select recipients, and pass optional API parameters such as email_ignore_missing.

cio.triggerBroadcast(1, { name: 'foo'},  { emails: ['[email protected]'], email_ignore_missing: true }
);

You can learn more about the recipient fields available here.

Options

• id: String (required)
• data: Object (optional)
• recipients: Object (optional)

cio.addDevice(id, device_id, platform, data)

Add a device to send push notifications.

cio.addDevice(1, "device_id", "ios", { primary: true });

Options

• customer_id: String (required)
• device_id: String (required)
• platform: String (required)
• data: Object (optional)

cio.deleteDevice(id, device_id)

Delete a device to remove it from the associated customer and stop sending push notifications to it.

cio.deleteDevice(1, "device_token")

Options

• customer_id: String (required)
• device_token: String (required)

cio.suppress(id)

Suppress a customer.

cio.suppress(1)

Options

• customer_id: String (required)

Using Promises

All calls to the library will return a native promise, allowing you to chain calls as such:

const customerId = 1;

cio.identify(customerId, { first_name: 'Finn' }).then(() => {
  return cio.track(customerId, {
    name: 'updated',
    data: {
      updated: true,
      plan: 'free'
    }
  });
});

Transactional API

To use the Customer.io Transactional API, import our API client and initialize it with an app key.

Create a new SendEmailRequest object containing:

• transactional_message_id: the ID of the transactional message you want to send, or the body, from, and subject of a new message.
• to: the email address of your recipients
• an identifiers object containing the id of your recipient. If the id does not exist, Customer.io will create it.
• a message_data object containing properties that you want reference in your message using Liquid.
• You can also send attachments with your message. Use attach to encode attachments.

Use sendEmail referencing your request to send a transactional message. Learn more about transactional messages and SendEmailRequest properties.

const { APIClient, SendEmailRequest } = require("customerio-node/api");

const client = new APIClient("your API key");

const request = new SendEmailRequest({
  to: "[email protected]",
  transactional_message_id: "3",
  message_data: {
    name: "Person",
    items: {
      name: "shoes",
      price: "59.99",
    },
    products: [],
  },
  identifiers: {
    id: "2",
  },
});

// (optional) attach a file to your message.
request.attach("receipt.pdf", fs.readFileSync("receipt.pdf"));

client.sendEmail(request)
  .then(res => console.log(res))
  .catch(err => console.log(err.statusCode, err.message))
