Veridion APIs use standard HTTP response codes to indicate various classes of success or error responses. Below is a list of the codes returned by our APIs.

HTTP Status	Description
`200 OK`	Standard HTTP successful response.
`202 Accepted`	The request was acknowledged and processed but no response was available. The caller should retry the request later.
`400 Bad Request`	Standard HTTP invalid request response. The request body does not match the expected schema or invalid parameters were passed. Check the error response `message` field for additional information.
`401 Unauthorized`	Standard HTTP unauthorized access response. Authentication is invalid. Check if the `x-api-key` header is passed correctly. Read more on Authenticating Requests.
