# End Points

> Get the production and test base URLs for the legacy Subscriptions v1 APIs, plus the API key authentication details you need to send requests.

Cashfree uses API keys to allow access to the API. Once you have signed up at our merchant site, you will see your AppId and SecretKey.

Cashfree expects the API key to be included in all API requests to the server. Use the endpoint **/api/v1/credentials/verify** to verify your credentials.

All API responses are in JSON format. POST requests should include ContentType: application/json
