Zoom SDK Error: Invalid Signature Despite No Code Changes

Hi everyone,

I was encountering an issue with the Zoom SDK and was hoping someone here could help. Here’s the situation:

I keep receiving the following error when trying to join a meeting via the Zoom SDK:
Sub-code: zoom_invalid_signature
Message: The Zoom SDK was not able to generate a valid meeting-join signature. This could mean that the meeting link is malformed, or the Zoom SDK credentials provided are invalid.

The strange thing is that the code hasn’t changed at all—it was working fine before, but now it suddenly throws this error. No modifications were made, and I’m using the same credentials, so I’m unsure what could be causing this.

Has anyone encountered a similar issue, or does anyone have insights into why this might happen?

Here’s what I’ve already tried:

  • Double-checked the credentials (API key, secret, etc.)
  • Regenerated the SDK keys
  • Verified the meeting link structure

Any help or suggestions would be appreciated!

Thanks in advance!
Itay
