## Zoom SDK JWT Token Generation Script
## This is for generating JWT token for Zoom SDK integration. 
## SDK JWT token is different from the JWT token use for API integration.
## We will include API JWT token generation soon. 

## Require: Python 3, pyjwt

## Prepare: 
## 1. Install Python 3, https://www.python.org/downloads/.
## 2. Add pyjwt lib, pip3 install pyjwt
## 3. Update the variables below with your keys & secrets. 
## 4. python3 zoom_jwtgen.py
