The Subscription End of Trial event triggers actions in your connected systems when a trial ends and converts into a paid subscription.
This event is often used to apply/remove tags in your CRM. This can be used for internal tasks, or to trigger automation in your CRM to deliver post-trial emails to your customer.
NOTE: If you have configured any Subscription Payment automation, it will fire around the same time, as the first payment is collected at the end of a trial.
This event is designed for triggering automation surrounding the trial ending (EX: Removing trial tags in CRM)
