Integrating Paypal payments in Flutter app

Question

I just started on my Flutter journey and need to integrate Paypal payments into my app. However, there seems to be no standard Flutter API provided by Paypal and I couldn't find an acceptable answer anywhere.

Solution 1

You can achieve this using WebView. PayPal provides some APIs to do transaction. Using those APIs you can achieve this.

Solution 2

Braintree is the payment processor provided by Paypal to accept safe and secure payments with feature Drop-in UI and custom UI design. It also provides the Apple Pay, Google Pay feature to accept the payments.

1. Open Braintree Sandbox Account

2. Get the tokenization key from Braintree account

3. Add the flutter_braintree dependencies in your pubspec.yaml file

   dependencies:
   flutter_braintree: ^0.5.3+1

4. Create custom UI

Paypal Credit card: accept the followings from user

a. Card Number

b. Expiration Month

c. Expiration Year

Create a Braintree Request

final request = BraintreeCreditCardRequest(

  card number: '4115511771161116',

  expiration month: '02',

  expiration year: '2020',

);

Ask Braintree to tokenization it

BraintreePaymentMethodNonce result = await Braintree.tokenizeCreditCard(

   '<Insert your tokenization key>',

   request,

);

For PayPal

create Paypal request

final request = BraintreePayPalRequest(amount: '50.00');

then launch Paypal Request

BraintreePaymentMethodNonce result = await Braintree.requestPaypalNonce(

   "Insert your tokenization key or client token here",

   request,

);

5. Get the NONCE from Braintree after successful payment and get the failure message on cancel the Paypal Payment by the user.

6. Save this NONCE for future reference in your database
