Under the hood, all Facebook APIs share the same infrastructure. Searching the Facebook Developers website may reveal more relevant information for your specific situation. You can also visit the Developer Support page, check open bugs, and drop by the Facebook Developer Community Forum.


The server-side API returns minimal data to conserve network bandwidth. If the event payload is valid, a 2xx HTTP response code is returned. If invalid, a 4xx HTTP response code is returned, with minimal error details in the response body.

You can get more detailed information for debugging any request by making a POST request to /events/?trace= in Graph API Explorer.

Options for trace include:

  • 1 - Error
  • 2 - Info
  • 3 - Debug

This API is under limited availability. Please contact your Facebook Representative if you believe that you have been granted access, but encounter one of the following errors:
