The Recharge Subscription Frequency Changed event triggers a Listrak Custom Event when a customer updates the frequency of their subscription order. In the journey, you can message a customer to confirm their subscription changes, display their billing details, and display the items included in the subscription.
This guide will outline the personalization options to customize the journey and messages triggered by the Recharge integration.

The Custom Event called Recharge Subscription Frequency Changed [[Your Store Name]] is automatically created as part of the integration process. Recharge passes the following payload to Listrak customized with the specific product information for the subscription.
