What type of event denotes a purchase made by a user in Braze?

In Braze, a purchase made by a user is denoted by a custom event. This is because custom events are specifically designed to track unique interactions or behaviors that aren't covered by the standard data types. When a user makes a purchase, it is a distinct action that can trigger various marketing responses or analytics tracking.

Custom events allow businesses to capture specific user activities—like purchases—and use that data for targeted messaging, segmentation, and insights. This capability enables marketers to tailor their engagement strategies based on users’ behaviors, ensuring that communications are relevant and timely.

On the other hand, custom attributes are used to store additional information about users, while standard attributes typically cover basic user data provided by Braze. Out of the box data refers to predefined attributes and events that Braze provides without customization, which would not capture the specificity of a purchase event. Thus, recognizing purchases as custom events is crucial for effectively leveraging user behavior data in marketing strategies.
