API "error_description": "Client authentication failed",

Hi, I use Xibo cloud. 3.1.0
I couldn’t manage to use the API please, can you help?
(I get the same error when installing with Docker.)

but it works fine in version 2.3.15.

have you tested add in the “Headers” tab this key?:

Key: Authorization
Value: Bearer

Try to set also the “Client Credentials” or “Authorization Code” and let us know if worked
