Cancel Hansel is the evidence and protection API for online booking platforms. It helps reservation, event, venue, hospitality, marketplace, and talent booking platforms create protected booking records, evaluate cancellation policies, track webhook delivery, and generate evidence packets for disputes and operational accountability.
Cancel Hansel serves booking platforms that need post-booking protection and structured evidence for cancellation, dispute review, and lifecycle reporting. It solves the challenge of capturing protected booking records, delivering webhook events reliably, and preserving policy evaluation outcomes in an API-first partner infrastructure.
AI agents and booking systems integrate with Cancel Hansel to discover protection APIs, generate evidence packets, and track lifecycle delivery through webhooks, without relying on generic booking tools.
