Guidelines for mobile integrations

SDK availability

Unzer currently does not provide dedicated device-specific SDKs for iOS or Android. To integrate payment solutions into mobile applications, use our provided UI components in combination with either the PHP SDK or Java SDK, both of which are actively maintained and regularly updated.

Alternatively, you can also directly connect to the REST API without using any of our SDKs.

Framework limitations

Note that several payment methods, including:

Apple Pay
Google Pay
PayPal

do not work reliably within WebView environments. Using these payment methods inside a WebView can lead to inconsistent user experiences and potential payment issues. So, we recommend avoiding WebView implementations for these specific methods.

Recommended implementation

Instead of WebViews, you can implement native, system-level browser solutions:

For Android: Use Chrome Custom Tabs.
For iOS: Use ASWebAuthenticationSession.

Using these solutions is reliable, compliant and secure, and delivers a consistent user experience across all supported payment methods.
