Integrating with PayPal, the online payment provider will be extremely easy using the O4W APIs.
Using the PayPal "Buy Now" feature, your customer can immediately purchase a single product from your website. Once your customer has selected "Buy Now" (either via a link or a button on your web page), your O4W stored procedure will use the O4WPayPal call to redirect the browser to PayPal's on-line payment site, where the transaction can be completed.
Using the PayPal "Add To Cart" feature, your customer can one or more products to the PayPal "shopping cart". Once your customer has selected a product to "Add To Cart" (either via a link or button on your web page), your O4W stored procedure will use the O4WPayPal call to redirect the browser to PayPal's on-line payment site, where the shopping cart can be reviewed. At that point, the customer can choose to return to your site for additional items, or can proceed to "checkout" on the PayPal site so the transaction can be completed.
Using the PayPal "View Cart" feature, your customer can review which products they have placed in their PayPal "shopping cart", modify their selections, or begin the PayPal checkout process.
