Understanding the "Destination URL Cannot Be on the Same Domain as Pabbly Hook URL" Message
When setting up a webhook in Pabbly Hook, you might encounter this error:
"Destination URL cannot be on the same domain as Pabbly Hook URL."
This message appears to ensure the webhook behaves as expected and avoids potential conflicts or recursion issues during execution.
Why This Restriction Exists:
- Avoid Infinite Loops: If the destination URL is on the same domain, it might trigger another webhook call back to the Pabbly Hook instance, creating an infinite loop of requests.
- Ensure Proper Execution: Webhooks are designed to send data to external applications or services. This restriction ensures the destination URL points to an external endpoint to process or utilize the data.
- Prevent Conflicts: Same-domain requests might lead to unintended behaviors, such as cross-domain or security conflicts.
How to Fix This Issue:
- Verify the destination URL you’ve entered.
- Ensure that the URL points to an external domain, such as your application’s API endpoint, server, or a third-party service.
