Overview 

Avangate supports 1-click purchases for returning customers who paid for their previous orders with:

• Credit/Debit cards
• PayPal

How does this work? 

1. Identify returning customers. 
2. Access data on the previous purchases of returning customers.
3. Validate previous order references for 1-click purchase scenarios using the isValidOrderReference method.
4. Place a new order using a valid previous order reference as the payment method. 
5. Avangate charges returning customers using their payment-on-file information, either a card or their PayPal account. 

Requirements 

• Use only references of previous orders  with one of the following statuses AUTHRECEIVED or COMPLETE.
• The email address of the BillingDetails object is mandatory and it needs to match the email address used as a part of the billing details of the initial order whose reference you're now using to place a new order. Avangate checks whether the email addresses are identical, and throws an error if they're not, blocking the order placement process. Note: You need to provide only the email address of the shopper, and can ignore the rest of the required customer billing information. If you enter any billing details in addition to the email address, you'll have to provide all information required in the BillingDetails object.​

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?

Availability

Please contact Avangate to start using one click (1-click) subscription renewals.

Requirements 

• Make sure that the subscription is eligible:
  • 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.

Overview

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

In this scenario, you can facilitate subscription upgrades for subscribers by enabling them to use card on file information to pay for the upgrade.

How does this work? 

1. Identify returning customers. 
2. Identify valid upgrade options and costs.
3. Create a tokenized manual subscription upgrade 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?

Availability

Please contact Avangate to start using one click (1-click) subscription upgrades.

Requirements 

• Configure the upgrade product / subscription plan in your Control Panel. 
• Email address must match that from the initial order. If shoppers change the email they need to re-enter the payment details.

Flow comparison

You particularly need either the Avangate customer reference or the external customer reference you control.

Validate upgrade options and costs

Create the manual upgrade link

To build custom upgrade links you need the following two elements:

1. The main upgrade path: 

https://secure.avangate.com/order/upgrade.php? or https://YourStore.com/order/upgrade.php? if you use a custom domain with Avangate 

2. The unique subscription identifier from the Avangate system: LICENSE=1234567.

The simplest upgrade link you can build is 

https://secure.avangate.com/order/upgrade.php?LICENSE=1234567

Attach the payment token to the manual Upgrade link
