Status Codes

When you call any of the Oracle Business Process Management REST resources, the Response header returns one of the standard HTTP status codes defined in the following table.

HTTP Status Code	Description
200 OK	The request was successfully completed. A 200 status is returned for a successful GET or POST method.
201 Created	The request has been fulfilled and resulted in a new resource being created. The response includes a Location header containing the canonical URI for the newly created resource. A 201 status is returned from a synchronous resource creation or an asynchronous resource creation that completed before the response was returned.
202 Accepted	The request has been accepted for processing, but the processing has not been completed. The request may or may not eventually be acted upon, as it may be disallowed at the time processing actually takes place. A 202 may be returned if an operation is still in progress or does not complete in a reasonable amount of time. The response contains a Location header of a job resource that the client should poll to determine when the job has finished. The response also returns an entity that contains the current state of the job.
400 Bad Request	The request could not be processed because it contains missing or invalid information (such as, a validation error on an input field, a missing required value, and so on).
401 Unauthorized	The request is not authorized. The authentication credentials included with this request are missing or invalid.
403 Forbidden	The user cannot be authenticated. The user does not have authorization to perform this request.
404 Not Found	The request includes a resource URI that does not exist.
405 Method Not Allowed	The HTTP verb specified in the request (DELETE, GET, POST, PUT) is not supported for this request URI.
406 Not Acceptable	The resource identified by this request is not capable of generating a representation corresponding to one of the media types in the Accept header of the request. For example, the client's Accept header request XML be returned, but the resource can only return JSON.
409 Conflict	The request conflicts with the current state of the resource.
410 Gone	The resource no longer exists.
412 Pre-Condition Failed	A required condition for the request is not met.
413 Request Entity Too Large	The body of a POST or PUT request is too large.
415 Not Acceptable	The client's ContentType header is not correct (for example, the client attempts to send the request in XML, but the resource can only accept JSON).
500 Internal Server Error	The server encountered an unexpected condition that prevented it from fulfilling the request.
503 Service Unavailable	The server is unable to handle the request due to temporary overloading or maintenance of the server. The Oracle Business Process Management REST web application is not currently running.
