Facebook Commerce Webhook

I'm trying to receive webhooks from Facebook commerce.

The pabbly pab receives the webhook and I can see it receives the information.

However, it fails because Facebook (Meta) needs a verification challenge sent back in the response.
  • The URL couldn't be validated. Response does not match challenge, expected value="1475563424", received="{\"status\":\"success\",..."
How can I make Pabbly send the hub challenge back to Facebook to verify?
Here is the webhook documentation: https://developers.facebook.com/docs/commerce-platform/order-management/webhooks

Please allow me some time to discuss this concern with my team. We will get back to you with an update soon.

I had a discussion with the technical team, and they informed me that you need to configure the webhook trigger and then issue a challenge. When they send a challenge or secret code to the webhook URL, you should return the same code or hashed value either in the response header or response body.

Please read the thread shared below to understand how you can configure and validate webhooks.
