We will retry if it’s a timeout which can be on our end or our partner’s end.
Error codes mean it succeeded from our end and the recipient responded with an error, and we don’t retry those.
Since most partners' errors are caused by misconfigured webhooks and it would create a no-value load on our system.
In addition, the 500 timeout error definition is based on our setting, not based on their system, we are waiting only 2 seconds and if they did not respond back within 2 seconds we will log 500 with the timeout error message.
It is possible that they could receive data even though there is a 500 response code with a timeout error in our postback logs. When we have a waiting time (2 seconds) less than what their server took to process the request then we could see a timeout error at our end.
Note: webhook_response_time_ms in the raw data is not the time between request and response. This returns a time from postback request creation to webhooks record logging.
