App Data API Errors
By calling this endpoint you will receive information about the App Data API tasks that returned an error within the past 7 days.
For example, if you have set tasks with webhooks (pingbacks and postback), but haven’t received them due to a server error, you can get a list of task IDs using the App Data API Errors endpoint, and use these IDs to resend webhooks.
Learn more in this help center guide.
Note that if a certain task does not appear on the list, this means the task did not respond with an error or has not been completed yet.
