I am trying to do the same thing, and the solution of using a header of "Authorization = Bearer {YourBearerToken}" worked for me. For context, before making the API call in Talend, I was using Insomnia (basically like postman). And for that, I was selecting "Bearer" from the list of auth types, and then putting in my token when prompted.
I only explain this to demonstrate that using the header as stated above seems to be equivalent to selecting the "bearer" auth type in some API client like postman, insomnie etc.
