Meeting SDK sample for React.js app working fine with [node.js signature app](https://github.com/zoom/meetingsdk-sample-signature-node.js). But I am trying to generate it using python as mention in the [documentation](https://marketplace.zoom.us/docs/sdk/native-sdks/web/signature/). Python 3 code generates an invalid signature due to which I am getting the error of Invalid signature while joining meeting. Moreover, There should be a python app for generating the signature as someone has already suggested on the Forum. Thanks for looking into it and let me know if I am missing something. Thanks in advance.

the python 3 script in the documention creates a **JWT Signature**  
the node.js signature app creates a **SDK JWT Signature**

they are not compatible

you can easily distinguish the signature routines:

- JWT Signature (deprecated) → time in **Milliseconds**
- SDK JWT Signature → time in **Seconds**

there is no example implementation for SDK JWT Signature in python until now
