With Chameleon's Customer.io integration, you coordinate lifecycle emails and campaigns with Chameleon product tours. To learn about Customer.io visit our integration page.

The Customer.io integration includes two components:

  • Data Destination -- send Chameleon data to Customer.io (to use in sending other messaging, such as emails)

  • Data Source -- get Customer.io data (webhooks) into Chameleon (for targeting Tours and personalizing content)

To configure this integration, go to the Integrations page on the Chameleon Dashboard, and find the Customer.io integration option.

Send data from Chameleon to Customer.io

To send automatically-collected Chameleon events to your Customer.io account, simply turn on the 'Send Chameleon data to Customer.io' toggle.

This will then send Chameleon events automatically to Customer.io from the client-side.

The Customer.io code needs to be installed on the pages of your product where Chameleon Experiences are seen by end-users, and users need to be identified with the same ID as they are to Chameleon.

The events sent by Chameleon are:

  • Started Tour (Chameleon)

  • Completed Tour (Chameleon)

  • Exited Tour (Chameleon)

  • Step Seen (Chameleon) -- by request, to avoid flooding you with events.

  • Previewed Tour (Chameleon) -- for admins only

You can view this within your Customer.io account, on the Activity page:

Event properties sent as part of these events include the Tour name, URL, and others where relevant (e.g. Step number).

You can then use this activity by users to be a part of an event-triggered email campaign. You can also use these events as part of your Customer.io segments, which can then be further used for any notification or message you send via Customer.io.

Get data into Chameleon using Customer.io webhooks

You can send data from Customer.io to Chameleon in real-time using webhooks. There are three types of data you can update within Chameleon using incoming webhooks.

  • User properties

  • Company properties

  • User events

You can then target Chameleon Experiences based on data sent by Customer.io, or use it to personalize content within Experiences (e.g. Step copy, variables within Microsurveys...), as below.


To set this up, start by visiting your Customer.io Integrations page, under Settings, and find the Webhooks option.

There will be two types available and you can use either or both to send data to Chameleon:

  • Reporting webhooks send data about message activity

  • Webhooks allow you to send a webhook to another service as part of a workflow or campaign.

In both cases, when setting up the webhook, you'll need the Endpoint URL and you can get this from the integration page in the Chameleon dashboard:


  • Use POST requests (to send data)

  • No specific Headers are required.

  • Authentication is built into the Endpoint URL (which contains your unique Chameleon account token)

  • If using a uid key (unique ID) for a user, ensure it matches the uid being sent to Chameleon as part of your Chameleon installation

  • Any data/content can be added as properties within the webhook request Body

What fields can be sent to the webhook in the JSON payload?
The webhook can be configured to "set user properties" or "log an event" simply by using a different endpoint in the Chameleon REST API. For the case of sending user properties you can send anything you would otherwise send to chmln.identify

For example you could set a property when a user reaches a milestone in your application, such as upsell_readiness_score, and use this as a filter within a Target Audience to show an Experience (e.g. prompting user to book a sales meeting).

What does each field do?
Fields are user properties and you are essentially using our REST API to update user profiles or to log events

What fields cannot be sent to the webhook?
Certain attribute names are reserved. These include id , created_at and are listed here.

While nested field two-levels deep are supported, further nesting (object within object within object) is not.

How do we map Customer.io User IDs to Chameleon UIDs?
Typically the 'User ID' (UID) you send to Chameleon (within the chmln.identify  call) is a Database ID and thus also used to identify users within Customer.io. 

To check the UID being sent for any Chameleon user, open the developer console and enter chmln.data.profile.get('uid').
