Intro

What are the digital wallets supported by Topper?

Topper currently supports Apple Pay, Google Pay, PayPal and Venmo on crypto_onramp flow only.

What are the benefits of using digital wallets as payment options?

These payment options offer a seamless and convenient way for your customers to complete transactions. Generally, users tend to prefer these over other payment methods when presented with the choice.

Mobile integration:​

  • If you are redirecting to Topper through the user's browser, no extra configuration is necessary.
  • When Topper is embed with a WebView, ensure setting is_android_webview=1 or is_ios_webview=1 as a query parameter in the URL.
  • When Topper is opened using a Safari View Controller, ensure setting is_safari_view_controller=1 as a query parameter in the URL.
