我们如何从贝宝获得交易费用金额？

Question

I am using PayPal iOS sdk to accept payment from user in my iOS app. I am using sandbox for testing. The payment is working fine, I am getting successful payment response along with Payment_ID. I am passing that Payment_ID to my server and from there using REST API (Show payment details), I am trying to retrieve all the information related to that payment but it is not consistent response.

Sometimes I am getting transaction_fee while sometimes it does not return in API response.

I see there is another NVP/SOAP method to get details but that requires transaction_id while i am only having Payment_ID.

does anyone have solution on how to get transaction fee from paypal?

Answer 1

I got the solution now!

I was receiving Payment_ID in response from from Paypal iOS SDk after payment successfully done. I am passing that to my server and the server is calling Show payment details REST API to get all payment details

GET /v1/payments/payment/payment_id

In above API response for some cases when transaction state is completed , paypal does not returning transaction_fee_amount . but it returns sale-->id (transactionId) .

Using Paypal PHP Library, I used that transactionId and made NVP call for below API, https://developer.paypal.com/docs/classic/api/merchant/GetTransactionDetails_API_Operation_NVP/

Voila!! In successfull response of that I am getting all the details for that transaction.
