Actions performed using custom codes

Restrict specific addons on selected plans based on the business use case

Solution

Custom Code is an additional feature that Chargebee provides to perform specific actions which are restricted via the API such as performing the subscription change either immediately or at the end of the term using the fetchChangeSubscriptionOptions.

Or actions related to the addons that can be performed using the fetchAllowedPlanConfig that would allow you to:

• Specify allowed addons

• Specify allowed addons for a particular plan

• Specify add-ons to be automatically attached to a plan when selected

• Specify quantity meta for a plan/addon

Note: It would not be feasible to restrict the downgrade of addon or remove the “-” button on the portal for changing quantity.
