(PowerBuilder) PayPal - Create Order

Creates a PayPal order.

"Creating a PayPal order indicates that the buyer has consented to the purchase but does not place the funds on hold. After you create an order, you can capture the order directly without any additional authorization or you can make an authorization API call to place funds on hold until you are ready to capture. Because the order does not place funds on hold, create an authorization instead of capturing an order directly.

Merchants often use this technique to accept orders for items that are not available for shipment when the order is placed. For example, when a merchant ships items from multiple distribution centers and needs separate authorizations for each shipment. Another example would be delayed shipping on items that are not in stock."

See PayPal Order Process for more information.

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