Application HTTP status codes table
Status code	Error message	Respond with status code when
`400`	JSON payload is missing a required key	The application payload is missing a required key.
`401`	Missing or Invalid X-Indeed-Signature value	The `Signature` value in the header is missing or invalid.
`404`	Job is invalid, does not exist	The job is invalid or does not exist.
`409`	Duplicate Application already in the system	The received application is a duplicate of an Indeed application in your system. Indeed excludes duplicate applications from automatic resends. A duplicate application is an application with the same job ID and from the same job seeker email as an Indeed application within the last 120 days. When you respond to a `POST` request, these applications are not duplicates: Applications originally submitted from a source other than Indeed. Applications from the same job seeker email to a different job ID at the same company.
`410`	The job is expired or no longer available	The job is expired or no longer available. Indeed expires the job from search results. If the job is in the XML at the next feed run, Indeed makes the job available again.
`413`	Payload is too large	The application payload is too large.
`422`	Unable to save application	The application is valid JSON but can’t be processed because it doesn’t match required schemas or specifications or is otherwise invalid.
