Connecting Customer.io

Connecting Customer.io to Stitch is a three-step process:

  1. Add Customer.io as a Stitch data source
  2. Generate a Webhook URL
  3. Set up webhooks in Customer.io

Add Customer.io as a Stitch Data Source

  1. Sign into your Stitch account.
  2. On the Stitch Dashboard page, click the Add Integration button.

  3. Click the Customer.io icon.

  4. Enter a name for the integration. This is the name that will display on the Stitch Dashboard for the integration; it’ll also be used to create the schema in your destination.

    For example, the name “Stitch Customer.io” would create a schema called stitch_customerio in the destination. Note: Schema names cannot be changed after you save the integration.

  5. Click Save Integration.

Generate a Customer.io Webhook URL

Once Stitch has successfully saved and created the Customer.io integration, you’ll be redirected to a page that displays your Customer.io webhook URL and token (which is blurred in the image below):

Customer.io Webhooks URL

Click the Copy button to copy it.

Note that this particular URL won’t display in Stitch again once you click Continue. Think of this URL like you would your login or API credentials - keep it secret, keep it safe. You can, however, generate another URL should you need it.

Once you’ve copied your webhook URL, click Continue to wrap things up in Stitch.

Set up webhooks in Customer.io

The last step is to setup webhooks in your Customer.io account.

  1. Sign into your Customer.io account.
  2. Click Integrations in the menu on the left.
  3. In the Streaming Data Out section, click the Get Started button next to Email Activity Webhook.
  4. In the Webhook Endpoint field, paste your Stitch-generated webhook URL.
  5. Next, you’ll select the Webhook Events you want to track:
    • To track specific events, click the Edit Webhook Events link (it’s under the Webhooks Endpoint field) to display the list of events:

      Setting up Customer.io webhooks.

      Use the checkboxes to select the events you want to track, clicking Save Changes when finished.

    • To track all available events, you don’t need to do anything else - skip ahead to the last step.

  6. Click Update.

Test the Setup

To ensure everything is set up properly, you can send a test call to your Stitch webhook by clicking the Test button next to the the Webhook Endpoint field.


Replication

After you’ve successfully connected your Customer.io integration, Stitch will continuously replicate your webhook data into your data warehouse.

Webhooks and historical data

Because Customer.io data is sent to Stitch in real-time, this means that only new records are replicated to your data warehouse. Most webhook-based integrations don’t retain historical data due to this as-it-happens approach.

In the event that our webhook service experiences downtime, you may notice some lag between an event occurring and the data appearing in your data warehouse.

Method

This version of Stitch’s Customer.io integration uses Append-Only Replication. Append-Only Replication is a type of Incremental Replication where newly replicated data is appended to the end of a table. Existing rows are not updated - updates are added to the end of the table as new rows. Data stored this way can provide insights and historical details about how those rows have changed over time.

Query for the latest data

If you simply want the latest version of the object - or objects, if you elected to track more than one during the setup - in the integration’s table (data), you’ll have to adjust your querying strategy to account for the append-only method of replication. This is a little different than querying records that are updated using updated_at Incremental Replication.

To do this, you can use the _sdc_sequence column and the table’s Primary Key. The _sdc_sequence is a Unix epoch (down to the millisecond) attached to the record during replication and can help determine the order of all the versions of a row.

Note: If you didn’t define a Primary Key while setting up the integration, the Primary Key for the table will be _sdc_primary_key.

If you wanted to create a snapshot of the latest version of this table, you could run a query like this:

SELECT * FROM [stitch-redshift:stitch-customerio.data] o
INNER JOIN (
    SELECT
        MAX(_sdc_sequence) AS seq,
        event_id
    FROM [stitch-redshift:stitch-customerio.data]
    GROUP BY event_id) oo
ON o.event_id = oo.event_id
AND o._sdc_sequence = oo.seq

This approach uses a subquery to get a single list of every row’s Primary Key and maximum sequence number. It then joins the original table to both the Primary Key and maximum sequence, which makes all other column values available for querying.


Schema

In v1 of the Stitch Incoming Webhooks integration, Stitch will create a single table - called data - in the webhook integration schema (this will be the name you enter in the Integration Schema field when you set up Customer.io) of your data warehouse.

The schema of this table will contain two “types” of columns:

  • Columns used by Stitch (prepended with _sdc), and
  • Columns sent by the provider’s webhook API

Aside from the Stitch columns, the schema of this table will depend entirely on Customer.io’s webhook API. With the exception of the _sdc fields, Stitch does not augment Incoming Webhooks data nor does it have any control over the fields sent by the webhook provider.


Webhook URLs & Security

Stitch allows you to generate up to 2 Customer.io webhook URLs at a time. These URLs contain security access tokens and as such, have access to your Customer.io account.

If you ever need to change your webhook URL, you can do so in the Integration Settings page after the integration has been created:

  1. Click into the integration from the Stitch Dashboard page.
  2. Click the Settings button.
  3. In the Webhook URLs section, click the Generate Webhook URL button.
  4. A new webhook URL will display. Press the clipboard icon to copy it.
  5. Follow the steps in the Setting Up Webhooks in Customer.io section to update the webhook URL in Customer.io.
  6. After you’ve updated the webhook URL in Customer.io, click the Revoke button next to the oldest webhook URL in Stitch. This will invalidate the token and revoke access.
