阅读更多关于 Disable shipping address option in PayPal Express Checkout

问题 Working with the PayPal API and using the Name-Value Pair Interface PHP source codes from SDKs and Downloads: Simplify Integrations with Downloads and SDKs. My question is similar to "Removing (or prefilling) the address details for PayPal Express Checkout" but I don't want shipping cost/address or anything related about shipping at all. I keep all shipping details on my system (even sometimes shipping doesn't even apply and there is no charge for it) and I just want user to pay through

Testing Paypal subscription IPN

阅读更多关于 Testing Paypal subscription IPN

问题 I'd like to test paypal subscription IPNs, both the ones received when a subscription is created, and the ones sent later with the next payment (such as monthly if the subscription is $x per month). However I'd prefer not to wait a month or a day to receive the second IPN. Is there a way to have an IPN sent quicker, such as hourly, using paypal or their sandbox? On the documentation it says you can only specify years, months, days, and weeks as the subscription period. 回答1: It used to be that

Why is DoExpressCheckoutPayment required for Paypal?

阅读更多关于 Why is DoExpressCheckoutPayment required for Paypal?

问题 I am trying to build a very simple paypal-backed shopping cart so users can purchase multiple items. I want paypal to handle all the payment details. I don't even want an order confirmation. I will manually check for order confirmation on paypal. At first I wanted to use "Website Payments Standard" because it seemed easy to create a form that will post to paypal and let paypal handle it from there.

阅读更多关于 Paypal REST API Adaptive / Multiple Payments (change payee)

问题 I\'ve just started looking at Paypal\'s REST api. One thing I can\'t seem to see is a feature paypal call Adaptive Payments. This allows me to register my app with my developer account, but not be involved in the actual payments. e.g. my app allows my users to accept payment for their services, which they sell through my app. I have been through Paypals REST API documents. I have worked out how to complete a payment, but all the transactions get sent through to my developer paypal account. I
