Attio Reference Architecture

Overview

Production architecture for CRM integrations with the Attio REST API (https://api.attio.com/v2). Designed for contact enrichment pipelines, deal tracking across custom lists, bi-directional activity sync with external systems, and workspace isolation for multi-tenant deployments. Key design drivers: webhook-driven data freshness, idempotent upserts via PUT assertions, schema-aware caching, and layered separation between API client, business logic, and infrastructure.
