Showing a PayPal button

Using our Payment Buttons

You can add PayPal payment buttons in your app through the Braintree SDK. The SDK will handle the loading and disable state of the button, call the `tokenize` methods with your request, and allow you a seamless branded experience in your mobile apps.

The SDK handles the complete payment flow internally, from launching the PayPal authentication to tokenizing the result, so you only need to provide your request configuration and handle the final nonce.

Here's how to integrate using SwiftUI:

let payPalRequest = BTPayPalCheckoutRequest(amount: "10.00")

let payPalButtonView = PayPalButton(
    authorization: authorization,
    request: payPalRequest,
    color: .blue, // choose between `.blue`, `.black`, `.white`
    width: 300
) { nonce, error in
    if let nonce {
        // handle successful PayPal payment
    } else if let error {
        // handle PayPal payment error
    }
}

Here's how to integrate using UIKit (wrapped SwiftUI):

let payPalRequest = BTPayPalCheckoutRequest(amount: "10.00")

let payPalButtonView = PayPalButton(
    authorization: authorization,
    request: payPalRequest,
    color: .blue,
    width: 300
) { nonce, error in
    if let nonce {
        // handle successful PayPal payment
    } else if let error {
        // handle PayPal payment error
    }
}

let hostingController = UIHostingController(rootView: payPalbuttonView)
addChild(hostingController)
