Hi @freddy
It looks like Charlie responded before I was able to over here: Frame.io V4 API – OAuth Token from Adobe IMS Not Authorized (401 on all V4 endpoints)
but to reiterate: make sure you’re including these scopes in your request to ims/authorize/v2:
offline_access, openid, email, profile, additional_info.roles
Also please make sure you have an adobe id connected to your frame.io account.
Please see Connecting to Adobe authentication | Frame.io V4 Knowledge Center
Hope this helps!
