What if the user doesn't get redirected after PayPal payment?

After adding stuff in shopping cart, clicking some Pay Now with PayPal button, and successful PayPal payment (PP or CC), it is logically possible that a user stays on PayPal website, if for example the Auto Return option isn't activated (or it is but it doesn't work because the user is a guest user without PP account)

The user can return to the site by clicking a link, but doesn't have to. My question is: if he doesn't, how will the site owner be aware that the user paid so that he can now send the items by post? That the site owner gets informed of being paid seems elemental to me, so I find incomprehensible that such elemental thing be left to some obscure Auto-Return option.

Please can somebody explain this to me?

I think the point may have been missed here. Or a problem does exist. If the purchaser uses CC, even if you have IPN set up and it works, but if the purchaser uses CC and does not click a button on the last page, which is not presented when using PP account, it is possible for the funds to go through, but no IPN, and so your website is unaware of the purchase. This last page, is an extra page that CC user gets after the page with the Pay button on it.

In this state, you can even go into IPN history, and the IPN is there, says it is sent, but it hasn't been. It does not get sent until after the purchaser clicks the button on the extra page and then they are taken to the auto return page.

This is a common challenge with any redirected payment gateway, and it's the reason most (if not all) of them implement some sort of asynchronous notification that a payment has been completed. In PayPal, this is the Instant Payment Notification (IPN). You must setup on your site either a generic IPN listener that you link to from your PayPal account profile settings or you can create a more targeted IPN listener specifically for your transactions and use the NOTIFYURL (or related) parameter in the form or API request you use to redirect to PayPal to send IPNs to that listener.

In my integrations, I never perform any order update or transaction logging when the customer returns from the site, preferring instead to wait for the IPN that I can validate and ensure came from PayPal as opposed to a spoofed return from someone trying to hack my checkout process.

For more information, see the IPN documentation: https://www.x.com/developers/paypal/documentation-tools/ipn/integration-guide/IPNIntro
