API triggered properties are useful for sending campaigns based on:

API triggered properties are particularly valuable for sending campaigns based on events occurring outside of Braze. This functionality allows marketers to utilize real-time data generated from various external systems or applications. For instance, if a user makes a purchase on an e-commerce platform or interacts with a third-party service that isn’t directly logged in Braze, an API call can be made to Braze to update the user’s profile with this information. This enables the creation of highly relevant and timely messaging based on the most current user behaviors and events, fostering a more personalized and engaging user experience.

The other options involve aspects that might be important for audience targeting or segmentation within a marketing strategy, but they do not capitalize on the dynamic nature of data flow that API triggered properties offer. User demographic information and subscription status changes refer to relatively static attributes that can be incorporated when a user is initially created or updated. User interaction with emails is typically tracked through Braze’s built-in analytics rather than needing an API to trigger responses. Thus, API triggered properties uniquely serve the purpose of integrating external event-driven interactions into the Braze ecosystem, allowing for more dynamic and responsive campaign management.
