- How do I create a custom event to track actions in my product?
- Can a custom event include default properties?
Say it to your AI assistant
- Create custom event {label} with properties {propertyDefinitions}, default properties {includeDefaultProperties}.
- Define event {label} on object {primaryObject} with fields {propertyDefinitions} ({includeDefaultProperties}).
