If you have several stores, you can link them all to one PayPal account. Online store takes care of proper values for each storefront and direct all sales to the PayPal account you select. All you need to do is enable the Auto return option:
- Log in to your merchant account in the PayPal backend.
- Go to Profile → My selling tools → Website Payment Preferences.
- Set the Auto return option to Enabled.
- Enter https://app.shopsettings.com to the Return URL field.
Online store will provide a URL with each payment request that overrides the Return URL field so your customers return to the site where they began the checkout process.
