Puzzle Integrations API

openapi: 3.0.3
info:
  title: Puzzle Accounting Accounts Integrations API
  description: 'RESTful, JSON API for Puzzle''s real-time financial data hub and general ledger. Puzzle builds a continuously reconciled general ledger on top of a company''s connected Stripe, bank, card, and payroll data and exposes the resulting transactions, ledger accounts, journal entries, financial statements, and startup metrics over HTTPS.


    ACCURACY NOTE (API Evangelist, 2026-07-01): The Puzzle API is real, documented, and RESTful, but is in an active-development, partner-gated rollout. Full endpoint schemas are behind a partner login, so this specification models the confirmed base URL, security scheme, and resource surfaces. The confirmed endpoint pattern is `GET /rest/v0/company/{id}/transactions`; every resource is nested under `/rest/v0/company/{id}`. Paths marked with `x-puzzle-unverified: true` follow the documented resource sections and this confirmed pattern but the exact operation paths were not individually verified against the gated reference. Verify against https://puzzle-api.readme.io/reference before production use.'
