That One Firm

The Protocols

CRM & API integrations

Connecting HubSpot, Salesforce, scheduling, and custom mobile surfaces without turning your stack into glue code forever.

Updated 2026-04-20 Machine doc: /ai-docs/crm-integrations.md

Principle

Your CRM should stay the system of record. Integrations should be documented, reversible, and least-privilege.

Patterns

  • Webhooks and batch sync where real-time is not required
  • Idempotent jobs so retries do not duplicate people or deals
  • Field mapping that survives vendor UI changes (versioned configs)

Handoffs

We deliver runbooks: what syncs, how often, how to pause, and who owns API keys.
