Hi @daichi @kirolive @david5 @pfa_zoom @jbassi ,
It’s been confirmed that the webhooks do not support OAuth or Server-to-Server OAuth tokens for cloud recording downloads. This is actually expected behavior and there’s been a request to change the documentation to correct the misguidance.
It is recommended that if you want to download cloud recordings after the webhook download_token has expired, use Zoom Meeting API .
I will submit a feature request to the platform PM to support S2S and OAuth tokens for webhook download_url.
FYI @elisa.zoom
Feature request ticket: Allow OAuth Tokens to Download Cloud Recordings from Cloud Recording Webhooks (ZSEE-92020), (DEVELOPERS-3922).
