I checked the authorization documentation as well as the talk-token-example on Github.
In the GitHub example a token is been created and a request is send to the server (simple cURL requests). In the example request which is send to the server, id 1 is submitted. Now the question: Where is the ID coming from? Is this an information which is loaded from the cookie? Somehow I have to submit this information from the server where the article and SSO is located to the server where Talk is hosted.
The solution I´m searching for is after the customer logged into our webpage, he is immediately logged into Talk. No more action is needed from customer perspective to log into Talk (neither via SSO, Facebook, Twitter, etc).
Many thanks in advance
