Handle the redirect
-
To complete the payment, redirect the shopper to the
action.urlreturned in the /payments response, taking into account the following recommendations:-
When using the HTTP GET method:
For security reasons, when showing the redirect in the app, we recommend that you use SFSafariViewController for iOS or Chrome Custom Tabs for Android, instead of WebView objects. Also refer to the security best practices for WebView. -
Redirection for mobile integrations:
For mobile integrations, we strongly recommended that you redirect the shopper to the default browser of their device. Redirecting to the default browser ensures the best compatibility, handling of multi-factor authentication, app-to-app redirection, and error handling.
-
-
After the shopper is redirected back to your website, check the payment result by making a POST /payments/details request, specifying:
details: object that contains the URL-decodedredirectResultreturned when the shopper was redirected back to your site.
