I don’t know who needs to hear this but I was struggling with Oauth2, especially because my client wanted uses to be able to connect a bunch of different services. I found Pathfix and it has saved the project for me.
Over at Pathfix they modified the plugin (several times) for my use case and just released an update.
I don’t have any monetary interest in them, I’m just super thrilled they helped me out and made such an awesome tool for bubble users like me. They have been nothing but tremendously helpful and responsive to requests.
Not only did they modify the plugin to allow a user to connect to one resource with multiple of the same type of account (ie: one user can now connect to 10 youtube channels), but they added several new places to connect to and features (YouTube Uploads, Vimeo Uploads, DailyMotion and some others).
I hope this helps someone!
