The Integration Problem in Real Estate
Most organizations run on a patchwork of 5–10 tools: CRM, ERP, accounting, ad platforms, and portals — each with its own data model.
When integration is missing, every team builds shadow processes: copy-paste operations, CSV exports, duplicate records, and late-stage reconciliation. That hidden workload can consume 20–30% of operations time.
What API-First Actually Means
Open platforms compound in value over time: each integration makes the next one faster, each webhook reduces manual dependency, and each API contract protects your ability to evolve without rewriting your stack.

Event Occurs
A domain action happens: new lead, unit reservation, or payment confirmation. The platform records a typed event.
Payload Constructed
Canonical JSON payload with event metadata, object identifiers, and a stable schema version.
HTTP POST to Your Endpoint
Delivered over HTTPS with signature headers for authenticity verification before processing.
Acknowledgment and Retry
Return 2xx to acknowledge. On timeout or non-2xx, QubeHub retries with exponential backoff for guaranteed delivery.
