Dear Stephan,
We already use the forum with sso inside a webview in an app. We want to integrate the forum in a new website we are building. I believe we have two options for this:
Option 1: implement several api’s (for example retrieving posts, categories and posting to discourse.)
Option 2: iframe the forum in our website in combination with sso. (cost efficient and we can see if the forum is a success prior investing into it)
So to answer your question: the iframe option does not have to do anything with the APIs.
Are there any plans in the nearby future to make the discourseSSO work in an iframe?
