We usually install our app through the REST api on our test instances. Trying to do so in the Confluence 10 milestone results in
Failed to install - status code: 403 - response text: Unknown Plugin Origin
How can we fix this?
Does it have something to do with the upcoming app signing? If so, where can I find details about it?
Thank you!
Edit:
The app management UI states:
Opt-In Period:
During the current opt-in period, you can choose to enable this functionality at your convenience. This period offers you the flexibility to adapt your workflow and ensure compatibility with your existing processes.
We did not opt-in (yet). So I would expect that the opt-in also applies to installs via the REST api, shouldn’t it?
