One of our customers would like to create issues in their Service Desk project through the REST API.
I tried to simulate this by inviting a customer to a testing project, creating API tokens for this customer and trying the REST API methods using Basic Auth . All calls that require authentication end up with a 401 response code.
I am sure the customer has the necessary permissions to see issues in the testing project, as the customer can log in and see the issues in the web interface.
I've tried making the same API calls using my own credentials and that works fine, so I think I'm making the calls correctly.
