Request Errors

In the events of API request errors, AfterShip uses conventional HTTP response codes in the 4XX and 5XX range to indicate the reason behind the error.

---

AfterShip uses conventional HTTP response codes to indicate the success or failure of an API request. In general, codes in the 2xx range indicate success, codes in the 4xx range indicate an error that resulted from the provided information (e.g. a required parameter was missing, a charge failed, etc.), and codes in the 5xx range indicate an error with AfterShip's servers.
