We use the Invoicing REST API for online payments, integrated into our website (online webforms). After filling in the webform, users are immediately directed to PayPal, where an invoice has been created for them. After payment, we would like them to return to a return url. In the Developer page with the REST API settings for Sandbox and Live there is a setting called 'Live Return URL', but this setting is not working. Is it possible to have a Return URL in place with the Invoicing REST API? For I can't find documentation about it on https://developer.paypal.com/docs/api/invoicing/ Active App feature options are: Accept Payments, Invoicing and Payouts. All help is much appreciated.
