Hello, I have a similar issue right now and I hope to get an answer on whether this is allowed or not.
For an extension I need the streamer to authenticate with Bungie using oAuth 2.0. As this is not possible using the config portion of the extension, I plan to use a self-hosted setup-site which will put the needed tokens in my EBS’s database. I use this on the EBS side to query and cache Destiny 2 data that I will then provide to the extension’s front-end.
Is this allowed?
