Zoom App returning "invalid signature" errors after reactivation - Need manual platform fix

Meeting SDK
1

Hello,

We have a published Zoom marketplace app that uses recall.ai to join meetings hosted by external customers. We’re experiencing persistent “invalid signature” errors that appear to require manual intervention on the Zoom platform side.

Timeline:

  1. The original app owner account was deleted, causing the app to become invalid

  2. During this period, “invalid signature” errors occurred as expected

  3. We assigned a new owner to reactivate the app

  4. We waited about 2 weeks before resuming use of the app

  5. We resumed using the reactivated app, expecting it to work properly

  6. However, “invalid signature” errors persisted for approximately 65% of all meetings

  7. We have now stopped using this app again due to these errors

Current Situation:

  • The app credentials appear to be configured correctly

  • The errors affect both internal and external meetings

  • recall.ai has confirmed this appears to be an internal Zoom platform issue requiring manual intervention

App Information:

@yoon.conner Would you be able to help us resolve this urgently? This is impacting our production service and customer experience.

Thank you for your assistance.

Hi @yamaryokw
Thanks for reaching out to us and welcome to the Zoom Developer forum!
Have you made sure that the client ID and client secret of the app when you assigned it to the new owner, remain the same ?
