Authentication

We implement Bearer token authentication to secure our APIs. This method requires you to include a valid token in the Authorization header of each request. The format is as follows: 
"Authorization": "Bearer <your_token>"
Replace <your_token> with the actual token provided to you by Commenda. Request API keys from the Commenda team for both testing and production.
