反应原生 - 使用 PayPal v2/orders 付款

Question

I am implementing PayPal in React Native, following the documentation for PayPal Payments v2 API

Here is the step by step of my checkout:

1. Use https://api.sandbox.paypal.com/v1/oauth2/token to get token.
2. Use https://api.sandbox.paypal.com/v2/checkout/orders to create an order
3. Use approve link for clients to accept payment
4. I set the return_url to be https://www.google.com/ . After clients accept the payment, I receive the return_url https://www.google.com/?token=<order_id>&PayerID=<payer_id>

At this point I'm stuck: how can I use the information order_id and payer_id ?

Answer 1

The next step is to do av2/orders capture of that order_id

Assuming success, the response's payments -> capture -> id value is what you should persist in your database for accounting purposes, as this is what will be searchable as the Transaction ID in the paypal.com account.

(The order_id has no accounting value, and should only be kept around ~1 month for debug purposes.)
