Unauthorized

This problem occurs when a client request lacks a valid access token, preventing the server from returning the requested resource.

Description

Your client application issued a request to an API without a valid access token, resulting in an unauthorized error.

Example

{
  "type": "https://dev.euipo.europa.eu/problems-registry/unauthorized",
  "title": "Unauthorized",
  "detail": "Access token not set or invalid, and the requested resource could not be returned",
  "status": 401,
  "instance": "/messages",
  "code": "unauthorized",
  "correlationId": "b8f2fc288f1e9aad434efdc96c255631"
}

Troubleshooting Steps

  • Obtain a valid access token: Ensure that your client application has a valid access token.
  • Include the access token in the request: Make sure the access token is included in the request headers.
  • Check the token's validity: Verify that the access token has not expired and is still valid.
  • Review the API documentation: Confirm the correct method for including the access token in your requests.
