沙盒中的Paypal付款数据传输未正确重定向

Question

I implemented a chained payment which is working perfectly well in the sandbox. However, I wanted to use Payment Data Transfer https://developer.paypal.com/docs/classic/products/payment-data-transfer/ instead of IPN since the user should be redirected directly and see the status of his payment. IPN is working fine, however, the redirect url is called without the needed parameter.

I've done the following to activate PDT

• activated automated redirect
• set my redirect url
• activated payment data transfer

The credentials I use are maintained in the developer area > sandbox accounts

For my payment I have to pass a redirect url as parameter since it cannot be null. This is the url which is called after my payment. However, it's not called directly and it's missing the parameter for the payment key.
