Subscription Swapped automation events are only available for Subscription Automation and are most commonly used to automate actions around a subscription upgrade or downgrade. You can setup these events to trigger an internal notification, apply/remove tags in your CRM or marketing automation tool, or any other integration action that you need.
There are two separate events available:
Subscription Swapped From
The Subscription Swapped From event will trigger when a customer’s subscription is changed FROM one plan/product to another. Use this event to run automation on a subscription to revoke access or remove tags when a customer is removed from that specific subscription plan/product.
Subscription Swapped To
The Subscription Swapped To event will trigger when a customer’s subscription is changed TO one plan/product from another. Use this event to run automation on a subscription to grant access or add tags when a customer is added to that specific subscription plan/product.
NOTE: If you need different actions to run on each Subscription Plan for Subscription Swapped From versus Subscription Swapped To, each Plan will need to be put into separate Subscription Groups.
