How to configure data routing for Signals Gateway
Updated Jan 16, 2026
In the process of setting up the Signals Gateway, data routing refers to adding a subdomain within the Signals Gateway.
Implementing a custom domain (data routing) in your Signals Gateway hub helps improve measurement performance. The data routing feature lets you specify the subdomain through which the pixel communicates with the Signals Gateway.
To configure data routing, follow the steps below:
1. Click on the left menu of your admin account, Account Settings → Data Routing → click Optimize.

2. Copy Signals Gateway domain.

3. Go to your DNS provider, in our case, it is Cloudflare. And add a new DNS record.

4. Specify the following configuration for the DNS record:
- Name: capig (or anything you prefer)
- Type: CNAME
- Content: the target domain that you have copied in the second step
- DNS proxy should be set to off.
Click Save.
Here is an example of DNS record configuration:

5. Go back to Signals Gateway and input your subdomain and domain following the hint within the interface.
Click Continue.

If everything has been set up correctly, the subdomain will appear under Data Routing, and a green Optimized indicator will be displayed.
