Errors

ATLPay 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 failed given the information provided (e.g., a required parameter was omitted, a charge failed, etc.). Codes in the 5xx range indicate an error with ATLPay’s servers (these are rare).

Some 4xx errors that could be handled programmatically (e.g., a card is declined) include an error code that briefly explains the error reported.

Error Codes

HTTP Code	Description
200 - OK	Everything worked as expected.
400 - Bad Request	The request was unacceptable, often due to missing a required parameter.
401 - Unauthorized	No valid API key provided.
402 - Request Failed	The parameters were valid but the request failed.
403 - Forbidden	You cannot access this resource.
404 - Not Found	The requested resource doesn’t exist.
500, 502, 503, 504 - Server Errors	Something went wrong on ATLPay’s end. (These are rare.)
