authorization - Paypal: Is there a way to check a cart right before a user pays? -

is there way paypal's api send site authorization request before completing user's payment?

i think reply here there no way this, 1 can set "authorization" cart parameter instead of "sale". still leaves question of how finish authorization in callback.

may clarify uncertainty extent.

authorization & capture starts when buyer authorizes payment amount during checkout.

for example, can utilize paypal express checkout api paymentaction element set authorization or order.

after buyer completes checkout, can utilize payment’s transaction id authorization & capture apis. can:

capture either partial amount or total authorization amount.

authorize higher amount, 115% of authorized amount (not exceed increment of $75 usd).

void previous authorization.
