# End Points

> Reference base URLs and authentication headers required to call the Cashfree Subscriptions APIs across the sandbox and production environments.

Cashfree uses API keys to control access to the API. After you sign up on the merchant site, you'll receive your `AppId` and `SecretKey`.

Include your API key in all requests to the server. Use the endpoint **`/api/v1/credentials/verify`** to verify your credentials.

All API responses are in JSON format. POST requests must include the header `Content-Type: application/json`.
