The Auto Return feature for PayPal Payments Standard redirects buyers back to your website after completing the payment. This feature replaces the PayPal-hosted Payment Done page with a page hosted on your website.

Here's how to enable Auto Return from the PayPal website:

1. Go to your Account Settings.
2. Click Website payments.
3. Click Update across from "Website preferences."
4. Click On under "Auto Return."
5. In the Return URL field, enter the URL where you want to send your buyer after the payment.
6. The Return URL is applied to all Auto Return payments unless otherwise specified within the payment button or link.
7. Click Save.

After you've set up Auto Return, you can use Payment Data Transfer to display the payment details to your buyer.

If you've enabled Auto Return and have also enabled PayPal Account Optional for new users, a new user won't automatically be redirected to your website but will have the option to return.
