Throughout the entire subscription lifecycle, the Purchasely Platform generates detailed Subscription Events.

These events enrich the foundational Transactional Events, which primarily focus on entitlement management.

By offering additional, real-time insights, the subscription events provide a comprehensive view of a subscriber's current status and progression within their lifecycle, enabling more targeted and effective engagement strategies.
