KISS API

Public API for Keep It Simple Storage (KISS). Integrate smart storage access into your platform.

White-label app operators — authenticate tenants via phone + OTP, retrieve unit access and lock keys, report lock activity.

PMS push integrators — two integration patterns depending on how your source produces data:

• Event-driven (email scrapers, webhook relays, MCP agents, any source producing sparse events): use POST /pms/events/move-in, POST /pms/events/move-out, and PATCH /pms/units/{crm_unit_id}.
• State-oriented (traditional PMS with an API that can produce full state on demand): use POST /pms/units/sync.

All PMS write endpoints (/pms/events/*, PATCH /pms/units/{crm_unit_id}, POST /pms/units/sync) accept an optional Idempotency-Key header for safe retries. The header is not used by authentication or log-reporting endpoints.
