React Native Midtrans is module for applicate Midtrans Payment Gateway, its use Midtrans Mobile SDK.

react-native-midtrans enable merchant to accept online payments in React Native apps. it use Midtrans Mobile user Interface SDK to make transactions on all the payment types supported by Midtrans. Watch the video for the default module example.

There are four parties involved in the payment process for making a payment.

1. Merchant Server : The merchant backand implementation
2. Customers
3. Midtrans Backend (Payment Procesor)
4. PaymentProject

Transaction Flow

1. Checkout: Customer clicks the Checkout button on the Host application and the app makes a request to the Merchant Server
2. Token request: Merchant Server makes a request to Veritrans server with Order Information.
3. Token response: Midtrans responds with a valid transaction token to Merchant server
4. Token response: Merchant server forwards the token to the Mobile SDK
5. Get transaction options: Mobile SDK requests payment/merchant information based on the token
6. Transaction options response: Mobile SDK renders the payment Options and payment information to make the payment
7. Pay: Customers selects the payment method and the payment details and clicks “Pay”
8. Charge: Mobile SDK sends the Charge request to the Veritrans Backend for payment Processing.
9. Charge response: Mobile SDK receives the response from the Veritrans Backend and triggers the handler on Mobile App with success/failure/pending status
10. Charge notification: Midtrans Backend sends a notification to the Merchant backend confirming the completion of transaction.
