Overview of the `subscription.activated` webhook

When a subscription.activated event is triggered, FastSpring sends a webhook payload containing details about a newly created subscription. This webhook only fires when a customer starts a new subscription, including new trials. It does not fire on rebills.

If webhook expansion is enabled, the payload includes full account and product objects. Otherwise, the payload includes only the corresponding IDs.

This page provides:

A full sample payload showing a populated subscription.activated webhook
A detailed table listing every payload property, including name, type, and description
Notes on field behavior, including how to detect trials and what's included when webhook expansion is enabled

Tip: Not all fields are always included. Refer to the Payload properties table to understand when a field appears.
