Step 2. Handle the redirect
To complete the payment, you need to redirect the customer to the correct URL in the response.
Response
transactionid=213592364&transid=213592364&status=2000&errormessage=pending&errmsg=pending&
amount=1.22&price=1.22¤cy=USD&orderid=Powercash21-Test&payment_method=117&
redirect_url=https%3A%2F%2Fwww.sandbox.paypal.com%2Fcheckoutnow%3Ftoken%3D8HB89670NU291814W&user_id=46930
When the customer finished or canceled the payment, he will be redirected back to url_return
, provided by you in the initial request to payment_preauthorize. After that, you will receive a notification, posted to notification_url
, with the final transaction status, which you suppose to use to update your system.
Notification URL can be configured by our tech support team in your account on our side,
or you can send it as a parameter notification_url
in the initial request to payment_preauthorize
.
url_return
andnotification_url

Refunds
PayPal supports refunds and can be initiated only on a successful captured transaction.
The request will send a credit note to the authorization system after the customer has already been charged. The refund amount will be credited to the customer, and the merchant’s account will be charged.
The refund can be done in two ways:
- Through API integration
- Through payabl. dashboard
If you have API integration, you can check more in our documentation Refund.
