Single sign on from Wordpress to Connect

It all comes down to how much scripting you want to do (or you want to pay someone to do).

You could use the simple method where the individuals joining the session are not registered users in Connect, so they just need to have guest credentials to get into a connect room. In that case you could just set up your call to the Connect room to be appended with their name, such as http://yourconnecturl/roomextention/?guestName=Bob%20Smith. They should be able to join the room and given the appropriate name. You could also look to use the room passcode feature to keep them from coming back to the room at a time where they are not supposed to be there, but that may or may not be an issue.

If you need the individuals to be registered users of your system, then you would need to create a script, using the Connect API, to check if they have an account, create one if they do not, log them in, and then pass the session id when logging into the room.
