Common API Responses

Unless otherwise specified each end-point can return the following responses.

Response: 401 Unauthorized

No response body.

In general 401 means an anonymous user attempted some action and was denied. Either the action is not granted to anonymous uses in the Drupal permissions, or XACML denied the action for the anonymous user.

Response: 403 Forbidden

No response body.

In general 403 means an authenticated user attempted some action and was denied. Either the authenticated user does not have a Drupal role that grants him/her permission to perform that action, or XACML denied the action for that user.

Response: 404 Not Found

No response body.

In general a 404 will occur, when a user tries to perform an action on a object or datastream that doesn't not exist. Or XACML is hiding that object or datastream from the user.

404 Responses can be returned even if the user was not determined to have permission to perform the requested action, as the resource must be first fetched from fedora before the users permission can be determined.

Response: 500 Internal Server Error

Content-Type: application/json

Name	Description
message	A detail description of the error.

Any problem can trigger a 500 error, but in general you'll find that this is typically an error returned by Fedora.
