How to edit/change subscription

Summary

Chargebee's checkout pages are available for creating a subscription with plans as well as one-time payment (non-recurring addons without a plan) checkout.

To know more about the one-time addon checkout process refer to this link.

Solution

To modify an existing subscription with an addon, a checkout page is not required because the customer's payment details are collected during the subscription creation, which is the purpose of a checkout. Instead, you can modify an existing subscription in the following ways:

1. Self-Service Portal - Customers can buy addons, apply coupons and make other subscription changes through their self-service portal accounts. They can also add/modify their billing and payment details here.

2. Via the Web Interface - Under the subscriptions tab, open the subscription to which you'd like to add the addon. Click on "Change Subscription" on the right and select the addons/coupons or make plan changes.

3. Using APIs -Use the Update Subscription API to add addons, apply coupons and make other subscription changes.
