​
Base URL

All API endpoints use the following base URL: 
https://transaction-tax.api.in.commenda.io/api/v1
All endpoint paths documented in this reference are relative to this base URL. For example, the tax calculation endpoint POST /calculate should be called as: 
POST https://transaction-tax.api.in.commenda.io/api/v1/calculate

​
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.
