Use
202
for times when the data is valid, but we've queued the persistence for background processing, as described in RFC 7231:The request has been accepted for processing, but the processing has not been completed.

Use
422
for validation errors, as described in RFC 2918:The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.
