Tracking Request Retry Behavior

See how Terminal49 retries failed tracking requests, which failure types trigger automatic retries, and how to inspect the current retry status via the API.

When you submit a tracking request, your request is added to a queue to be checked with the shipping line. What happens if the request does not go through correctly?

If Terminal49 has difficulty connecting to the shipping line or cannot parse the response, it retries up to 14 times with exponential backoff. This process can take up to approximately 24 hours. You do not receive a tracking_request.failed webhook notification until all retries are exhausted.

If the shipping line returns a response that it cannot find the provided number, Terminal49 immediately sends the tracking_request.failed event to your webhook.

To check the status of your tracking request, make a GET request using its id to see how many times it has retried and what the most recent failure reason was.
