HTTP Status Codes

Domec 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.), and codes in the 5xx range indicate an error with Domec’s servers (these are rare we hope).

Not all errors map cleanly onto HTTP response codes, however.

When a request is valid but does not complete successfully (e.g., a card is declined), we return a 402 error code.

HTTP status code summary

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.
404 - Not Found The requested resource doesn’t exist.
409 - Conflict The request conflicts with another request (perhaps due to using the same idempotent key).
429 - Too Many Requests Too many requests hit the API too quickly.
500, 502, 503, 504 - Server Errors Something went wrong on Domec’s end.
