Hi,
This is an interesting use case, however, I do not think we have webhooks for meeting expiration. However, here is a work around that you can implement:
- Subscribe to the meeting has been created / updated webhook
- Identify the meetings that are instant, by looking at the meeting type (1 for instant meeting)
- Create a logic at your end which invalidates the cache after 24 / 48 hours after the “created_at” field from the payload.
Let me know if this helps
