(I couldn’t find an org-level discussions or anything like it, so hopefully this is the most relevant repo for requests like this. 😅)
Both Overseerr and Jellyseerr (which is a fork of Overseerr with Jellyfin/Emby support) publish Swagger-compliant APIs, so I believe this would be relatively straightforward to support, but I’m not exactly sure what it would take to provide initial support.
I’m not familiar with writing Terraform Providers, but if that would help speed this along, I could definitely give it a go.
It seems that Jellyseerr publishes a YAML version of their API here. Overseerr does similarly here.
