Get started with Reactors

Learn how to use reactors to automate loyalty logic in response to user actions. Covers triggers, conditions, and reactions with practical examples and implementation tips.

What are reactors?

Reactors are a core component of the Loyalty Engine. They automate what happens when a customer performs a specific action—like making a purchase, referring a friend, or reaching a milestone.

Each reactor is made up of three key parts:

Trigger

The event type that activates the reactor. This could be a purchase, referral, account creation, or any other event you define.

Conditions

Logic that decides whether the reactor should respond to the event – such as if a specific product was purchased, or if the user is in a particular audience.

Reactions

What happens when a trigger fires and conditions are met – such as adjusting points, issuing a reward or calling a webhook.
