Digits Transactions API

openapi: 3.1.0

  title: Digits Connect API
  version: 1.0.0
  description: >-
    The Digits Connect API provides programmatic access to the Autonomous
    General Ledger (AGL), Digits' AI-native general ledger. Partners send raw
    transaction, party, and dimension data via source sync endpoints, where the
    AGL researches vendors, enriches profiles, and posts fully categorized
    entries. Read endpoints return ledger transactions, parties, categories
    (chart of accounts), dimensions, and standard financial statements.


    Authentication is OAuth 2.0 (authorization code grant). List endpoints use
    cursor-based pagination. Source sync endpoints are idempotent and
    deduplicated via the external_id field.


    NOTE (API Evangelist honesty note): Digits does expose a real, documented
    public first-party API (the Digits Connect API) at
    https://connect.digits.com/v1 with OAuth 2.0 and an interactive reference at
    https://developer.digits.com. This document is a hand-authored, honest
    representation of the documented service methods; it is NOT the vendor's
    machine-generated OpenAPI. The public https://digits.com/openapi.json file
    describes only marketing-site/MCP-discovery metadata, not the Connect API.
    Request/response schemas below are summarized, not exhaustive. Verify exact
    paths, parameters, and payloads against developer.digits.com.
