HTTP Status Codes

Krayon Digital uses conventional HTTP response codes to indicate the status of issued API requests. Krayon conforms with the HTTP status code numbering conventions:

Code range 2xx indicates success cases.

Code range 4xx indicates errors when failing to provide the required input information, for example, a required parameter was omitted. Some errors, such as when a transaction fails, provide additional details to explain the error and how to mitigate it.

Code range 5xx indicates an error from Krayon Digital's servers (these are rare).
