JB360 Docs

Handover documentation for the ServiceTitan integration — codebase, live AWS environment, and database. July 2026.

The Three Codebases

extraction (Java sync worker), jbw-sam (serverless backend), and jbwui (React portal) — with per-class, per-Lambda, and per-component code references.

Live AWS Environment

206 Lambdas, 20 sync schedules, queues, and network — and how far reality has drifted from the SAM template.

Database & Matching Logic

The jbwst schema — 44 tables, 12 views, and all 10 stored procedures explained, including the matching engine.

ServiceTitan Contract

App registration, scopes, per-tenant OAuth, endpoint inventory, and everything JB360 writes into ST.
