There are aMember invoice links that look like this: https://mysite.com/amember/pay/212S3-8fj39fj4sl. I can see them for users who have pending invoices, but I'd like to know how I can generate these links myself. So for instance I have a user with username MemberY and I'd like him to purchase product #2. Is there a simple way I can generate an invoice link without the user doing anything? This would be very useful, I'd like to use the links similarly to PayPal's new https://www.paypal.me/accountnamehere/60 links that take you directly to an invoice.
