Hi @Erek Bond
Did you resolve your issues? I am going through this now, but did not have a problem with the linking. We do have a couple of different GTW accounts, so you need to create a separate LaunchPoint service for each login...

You need to make sure that you logout of GTW before you set up each LaunchPoint service, because it will default to any active login sessions.
Like Josh said, the event needs to exist for the integration to see it. I go into GTW first to create the event and turn off all of the notifications/emails. Then go into the Marketo event.
Thanks for the reply, Blane. I figured it out this morning. The issue was the integration user we set up for GTW needed to be added as an organizer for each webinar. We have multiple users setting up multiple webinars in GTW. Marketing Operations does not create the webinar in our process, that responsibility lies with the marketing manager that owns the webinar. The documentation was clear that the integration user needed to be an admin, but I didn't see anywhere where it said that the user needed to be added as an organizer for each webinar. I suppose it may have been implied, but it wasn't something we had to do with our previous MAP.
