API Response Codes

This section outlines the standard response codes returned by our API. These codes provide information about what went wrong with a request and help developers diagnose and resolve issues effectively. Each code is accompanied by a human-readable message to assist in understanding the context of the error.

In every API response, you’ll find a meta object that contains the code and message fields. The code is a machine-readable identifier representing the result of the request, while the message provides a human-readable explanation of the code when applicable. A successful response typically includes a code of 1000 and a message of null. For error responses, the code corresponds to one of the values listed below, and the message will contain a descriptive explanation to help guide error handling.

All AdFlex API responses return the fixed HTTP status 200 OK, including application-level errors. Clients must inspect the internal code field in the response body to determine the actual result.

Note: The HTTP status is always 200 OK and does not represent the application result. Always use the response-body code field for success and error handling.
