Errors

The ABCC API uses HTTP status codes to indicate the success or failure status of an API request.

• Return HTTP 2XX to indicate that the API request was successful

• Returning HTTP 4XX indicates that error information was provided when requesting the API, such as missing parameters, parameter errors, and account balance errors, etc.

• Returning HTTP 5XX indicates that the server sent an error during the API request.
