# End Points

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`.
