I use Paypal Rest API and my question is:
How long is token from approval URL valid? I want to store this token (also with my token) to the database and generate link with my token. Later if I click to this link (replace my token with paypal token) I want to redirect to paypal.
If i tried some old token, paypal site get error with "This transaction has expired" and "Your session has ended".
Example of approval URL:
https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-2W069482J43318257
Thank you. Have a nice day :)
They say it expires after 3 hours, and you can extend it to 72 by contacting customer service. Used it, but never contacted them, so...
