Invalid client id



I am trying to call the Settings API.


I created an API only user and also created the client Id and secret. But when I use them to get the OAuth Bearer Token I get the message "Invalid client id" when trying to call "".


Other APIs seem to work. For example, I can call "" with my username and password. I can retrieve the products data.


Does anyone know why my Client ID looks bad? I have created a few of them...
