Branch

Connecting Branch

Connecting Branch to Stitch is a three-step process:

1. Add Branch as a Stitch data source

2. Generate a Webhook URL
3. Set up webhooks in Branch

Add Branch as a Stitch Data Source

1. On the Stitch Dashboard page, click the Add an Integration button.

2. Click the Branch icon.

3. Enter a name for the integration. This is the name that will display on the for the integration; it’ll also be used to create the schema in your data warehouse.

   For example, the name “Stitch Branch” would create a schema called stitch_branch in the data warehouse. This schema is where all the tables for this integration will be stored.

4. Click Save Integration.

Generating a Branch Webhook URL

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

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.

Setting Up Webhooks in Branch

The last step is to setup webhooks in your Branch account.

For additional info on Branch webhooks, check out Branch’s webhooks documentation.

1. Sign into your Branch account.
2. In the side nav, click the webhooks option.
3. Click Add a new webhook.
4. In the window that displays:
   • Paste your Stitch-generated webhook URL in the URL field.
   • Leave the method (POST) as-is.
   • Set the notification frequency using the drop-down menu. You can choose to receive a webhook for every single event occurrence or only for the first time that event is triggered for a unique user.
   • Set the event trigger using the drop-down menu.
5. When finished, click the Add webhook button.

Replication

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

Webhooks & Historical Data

Because Branch 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 Branch 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 - any updates will be added to the table as new rows. Data stored this way can provide insights and historical details about how those rows have changed over time.

Querying 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.

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-branch.data] o
INNER JOIN (
    SELECT
        MAX(_sdc_sequence) AS seq,
        [primary-key]
    FROM [stitch-redshift:stitch-branch.data]
    GROUP BY [primary-key]) oo
ON o.[primary-key] = oo.[primary-key]
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 Branch) of your data warehouse.

The schema of this table will contain two “types” of columns: columns used by Stitch (prepended with _sdc) and the columns sent by the provider’s webhook API.

Aside from the Stitch columns, the schema of this table will depend entirely on Branch’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 Branch webhook URLs at a time. These URLs contain security access tokens and as such, have access to your Branch 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 Branch section to update the webhook URL in Branch.
6. After you’ve updated the webhook URL in Branch, click the Revoke button next to the oldest webhook URL in Stitch. This will invalidate the token and revoke access.
