Paypal: Cancel or timeout a payment

Question

I'm using Adaptive Payments API in order to create a new parallel payment. I'm reading documentation but I still have some questions:

• Is there any API operation for cancel this payment (obviously, sending payKey)?

• When I create this payment, can I specify a timeout?

• What is the default timeout for a paypal operation?

Thanks.

Answer 1

Well, same question asked and answered in the PayPal X Developer Network:

At this time, there is not a way to cancel a paykey and a timeout value cannot be specified. The default timeout value for PayPal is 5 minutes (after being inactive) however a paykey is good for 3 hours. So if the user were to copy the redirect url (before logging in), that url (with paykey) would be good for 3 hours.
