Authorization & Capture API

DoReauthorization

To use DoReauthorization you must have previously authorized a transaction. You can

authorize a transaction in several ways:

–From the Merchant Services tab of your PayPal merchant account.

– With the DoExpressCheckoutPaymentRequest PaymentAction element set to

Authorization.

– With a shopping cart transaction (such as one that uses PayPal Website Payments) with

the paymentaction HTML variable set to authorization.

You can invoke DoReauthorizationRequest as many times as necessary to obtain one

successful reauthorization. When DoReauthorizationResponse returns success, the

settlement period restarts, you can capture funds, but you can no longer reauthorize.

NOTE: DoReauthorizationRequest is for use only with basic authorizations, not order

authorizations.
