Tattle Open API
Tattle describes an open, REST-based API and an API-first design ("Modern REST APIs with comprehensive documentation for custom integrations") enabling two-way data synchronization with restaurant POS, online ordering, loyalty/CRM, and kiosk systems so brands can incorporate Tattle into their tech stack. The company also builds custom integrations on request. No public API reference, base URL, authentication, or webhook documentation is published; access is coordinated through Tattle's integrations team.
