Error Reporting
The application/problem+json (Problem Detail) MUST be used to communicate details about an error.
Problem Detail is intended for use with the HTTP status codes 4xx and 5xx. Problem Detail MUST NOT be used with 2xx status code responses.
At minimum, any Problem Detail response MUST have the title and detail fields.
Example
{
"title": "Authentication required",
"detail": "Missing authentication credentials for the Greeting resource."
}
Optional Fields
It SHOULD have the type field with the identifier of the error, in addition it MAY have the instance field with the URI of the resource in question. If the Problem Details responses has the status field it MUST have the same value as HTTP Status code from of the response.
{
"type": "https://adidas-group.com/problems/scv/unauthorized",
"title": "Authentication required",
"detail": "Missing authentication credentials for the Greeting resource.",
"instance": "/greeting",
"status": 401
}
Additional Fields
If needed, the Problem Detail MAY include additional fields, refer to RFC7807 for details.
Example
A request is made to retrieve a resource representation:
GET /greeting HTTP/1.1
Accept: application/hal+json
However in order to make this request the client needs to be authorized. Since the request is made without the authorization credentials the 401 Unauthorized response is returned together with details using the application/problem+json media type:
HTTP/1.1 401 Unauthorized
Content-Type: application/problem+json
Content-Language: en
{
"type": "https://adidas-group.com/problems/scv/unauthorized",
"title": "Authentication required",
"detail": "Missing authentication credentials for the Greeting resource.",
"instance": "/greeting",
"status": 401
}
