One click (1-click) subscription renewal

Overview

Avangate supports 1-click manual subscription renewals for returning customers who paid for their previous orders with Credit/Debit cards.

In this scenario, you can facilitate subscription renewals for subscribers who opted out of auto-renewal (recurring billing).

How does this work? 

1. Identify returning customers. 
2. Generate the manual renewal link.
3. Create a tokenized manual subscription renewal link and serve it to the returning customer.
4. Customers using the link land a hosted shopping cart, chose one of their credit cards they previously used for purchases from your account/store and place the order.

What do shoppers see in the cart?

  • Status needs to be Active or Past Due
  • Subscription cannot be evergreen​
• Email address must match that from the initial order. If shoppers change the email they need to re-enter the payment details.
