问题
When I create an agreement for paypal payment, it return the REDIRECT link with a token.
The user must connect to paypal via this link and accept agreement, then I can execute agreement.
I want to know, how long the REDIRECT link (and its assoicated token) is valid ? I ask because I want top precompute agreement and put them in cache, so If user want to subscribe I use a cached REDIRECT link and it's fast. Create agreement call take 2 seconds, it's too long, speed is critical at checkout stage.
I use the REST API + Java.
回答1:
Express Checkout tokens (which is what REST API returns for the Billing Agreement calls) expire after 3 hours.
