AppFolio Reference Architecture

Overview

Production architecture for property management integrations with the AppFolio Stack API. Designed for multi-property portfolios requiring real-time vacancy tracking, tenant lifecycle management, work order routing, and accounting reconciliation. Key design drivers: data freshness for leasing decisions, idempotent sync for financial accuracy, and tenant-facing portal responsiveness.

Prerequisites

• A provider-verified contract for endpoints, authentication, events (if any), rate limits, data residency, and permitted downstream accounting/CRM effects.
• Separate staging and production environments with managed secrets, synthetic fixtures, durable queues/idempotency stores, and named reconciliation owners.
• Data classification that limits dashboard and cache models to the smallest permitted fields; tenant contact, payment, and balance data require separate encrypted stores and access controls.
