# API Settings

API settings can be found under your merchant account. This information is necessary for Monri WebPay service to work properly. API settings values reflect a configuration at the merchant site:

## Cryptographic keys

- **Key**: This is a unique, secret main key used for encryption. In Monri's system, it's used to calculate the digest value, which verifies the source of a request.
- **Authenticity token**: This is a public, secondary key found in your merchant settings.

## Monri Responses and Redirect

- **Success URL** is an URL at the merchant site where a buyer is redirected after approved authorization.
  - Redirect to success URL should be set to true if merchant parses the data carried in redirect to success URL, ie. a listener will wait for this request and update order status.
- **Cancel URL** is an URL at the merchant site where a buyer is redirected if cancel link is clicked at payment form
- **Callback URL** should be set under merchant profile if the merchant wants us to send POST request message for each approved authorization

`IMPORTANT` Parametrize these values for API settings, we strongly advice a merchant to have both, testing and production environments.
