Hi @KMA , can you please confirm that the person calling the endpoint has the correct role permissions?
If they do, please try removing the scope, regenerating the application credentials, re-adding the scope, creating a new access token and calling the endpoint.
I’d check the role angle Gianni mentioned first. list_summaries is an admin scope, so the app’s creator needs an owner or admin role, or a role that includes that access. Once the list call works, keep in mind it only returns metadata. You still need GET /v2/meetings/{uuid}/meeting_summary for each item, and the page token expires after 15 minutes. If the real goal is just getting all the summaries out rather than the Make flow itself, I’m building a bulk exporter on these endpoints and can share it.
