PayPal - Authorize a Payment

See more PayPal Examples

Creates an authorization for a payment. This is for the case where the payment will first be authorized, and then captured at a later date. (In other words, the buyer is providing his/her credit card information now, and the actual charge (capture) will take place at a later time.)

Creating the authorization is the same as creating "sale" payment, except the intent is set to "authorize" instead of "sale".

This example requests an authorization for a credit card payment (using a credit card ID previoulsy stored in the PayPal vault).

Note: This example requires Chilkat v9.5.0.65 or greater.
