I am working on a project where I need to open the QuickBooks Online invoice payment page for customers.
I want to generate a direct payment link using the invoice ID so that customers can pay their invoices without logging into QuickBooks manually. I tried constructing a direct payment link like:={invoice.Id}. But this redirects to the QuickBooks login page, which is not ideal for customers. I checked QuickBooks API documentation but could not find a consistent way to retrieve a customer-facing payment link. Is there a way to get a QuickBooks Online payment URL using Invoice ID without logging in. Any help would be greatly appreciated!
