You aren't limited to this exact flow, but it can be a helpful jumping off point as you plan your Payment Settings integration. ## Retrieve Payment Settings 1. A site visitor clicks on the "Place Order" button in their Wix checkout, and an online payment is required. 2. Wix sends a [Get Payment Settings service plugin](https://dev.wix.com/docs/rest/business-solutions/e-commerce/service-plugins/payment-settings-integration-service-plugin/get-payment-settings.md) request to your app. 3. Your server handles the request and returns the payment settings. Example of a payment settings response from your app: ```json { "paymentSettings": { "requires3dSecure": true } } ``` 4. Wix passes the payment settings to the payment provider to continue the payment process.
