Overview

Use the convertTrial method to convert a trial to a paid subscription. In the eventuality of a conversion failure, you can use convertTrial again for the same trial subscription only after you let 24 hours pass since the initial attempt. The 2Checkout system attempts to automatically convert trials before they expire to full subscriptions unless you made an attempt that failed less than 24 hours before the scheduled expiration deadline.

In case the trial conversion fails due to a transaction issue, the 2Checkout system sends unfinished payment follow-up emails to customers, provided that you set up lead management for your account.

Overview

Use this object to retrieve information about the cross-sell campaigns you configured for your account. 

Parameters

Overview

ConvertPlus offers support for multiple checkout options with/without a review page. As a merchant, you have the possibility to define your own purchase flows with/without review and offer your shoppers the optimal checkout experience. By including a review page before your shoppers finalize their purchase you give them the opportunity to review their order and go back to update their checkout details.

Availability

Available to merchants using the ConvertPlus shopping cart, only for default and one-column templates.

Benefits

• According to our research, the checkout with review is currently among the best converting shopping flows on the 2Checkout platform
• It can increase your conversion rate in some countries
• Shoppers can review all the information in their shopping cart on an all-in-one page (shopping cart, billing form, and credit card form)

Workflow

To implement the checkout with review follow these steps:

1. Log in to your 2Checkout Merchant Control Panel account.
2. Navigate to Setup → Generate links.
3. On the Checkout links page, click on the ConvertPlus tab.
4. In the ConvertPlus flows section, select the Checkout with review option.

5. Continue with the selection of one or more products from the drop-down list.

6. Scroll down to the Checkout link section and click on Generate link.

7. After you generate a buy-link in with the review flow enabled, the buy-link contains the review=1 parameter and the checkout page will look like in the image below. At this point, the shopper can click on Continue to review before they place the order.

8. On the Review page, before hitting the Place order button, the shopper can edit the order details, the billing details, and/or the card details by clicking on the Edit links, as shown below.

• When clicking on the Edit link in the Order summary section, the shopper is redirected to the Secure Checkout page to edit the order details
• When clicking on the Edit link in the Billing information section, the shopper is redirected to the Secure Checkout page to edit his details
• When clicking on the Edit link in the Payment information section (card no. and security code obfuscated), the shopper is prompted with the Payment details form to edit CC details
• When clicking on the Edit link in the Delivery information section, the shopper is redirected to the Secure Checkout page to edit the delivery details
• When selecting a different payment method from the review page, the shopper is redirected to the checkout page with the new payment method

Overview

Use the addPriceOptionGroup method to create price option groups for your subscription plans/products.

• Send options for each pricing group or 2Checkout throws an exception.
• When adding an interval with no min/max values or overlapping values, 2Checkout throws an exception.
