Steps
Have the client post the custom event first (e.g., via WritePlayerEvent) since Game Manager only offers an event as a Rule trigger after it has been seen at least once
In Game Manager, go to Automation > Rules > New Rule and select the event as the Trigger
Add an optional Condition to filter out events that don't meet criteria, such as a specific field value
Attach a built-in Action (e.g., increment a statistic already defined under Leaderboards) or replace it with a Cloud Script Action for custom logic
Use the PlayStream Debugger in Game Manager to watch the trigger fire and confirm the configured action executes
Known gotchas
A Rule can only be created against an event name the title has already posted at least once — you can't pre-create a Rule for an event type that hasn't fired yet
The built-in statistic-increment action requires the target statistic already be defined under Leaderboards in Game Manager before the Rule can reference it
Rules are limited to exactly one Trigger each; more complex branching logic has to move into the Cloud Script Action rather than being expressed as multiple triggers on one Rule
