description: 'Ally Financial (NYSE: ALLY) is a US super-regional, all-digital bank holding company and one of the country''s
  largest auto finance providers, offering online deposit accounts, auto and personal lending, mortgages, credit cards, and
  self-directed and robo brokerage through Ally Invest. Ally does not operate a live, self-serve first-party public developer
  portal for its consumer banking products. Programmatic access to Ally Bank account and transaction data is delivered through
  third-party open-finance aggregators (Plaid and Flinks are documented), and the legacy Ally Invest brokerage REST API (inherited
  from the 2016 TradeKing acquisition) has effectively been retired as Ally Invest shifted toward managed and robo portfolios.'

apis:
- name: Ally Financial Platform (Conceptual Model)
  description: A conceptual, API-Evangelist-derived domain model of Ally Financial's consumer platform spanning deposit accounts
    (checking, savings, money market, CDs, IRAs), lending (auto, personal, mortgage, home equity), self-directed and managed
    investing, and dealer/auto-finance services. This is NOT a live, published public API - Ally exposes no self-serve first-party
    developer portal for these products. The model is provided for API design discussion, gateway/GraphQL modeling, and catalog
    discoverability only; consumer data access in production is via open-finance aggregators.

- name: Ally Invest API (Legacy / Retired)
  description: The legacy Ally Invest brokerage REST API, inherited from Ally's 2016 acquisition of TradeKing. It offered
    OAuth 1.0a authenticated access (consumer key/secret plus OAuth token/secret) over documented resource groups - Accounts
    (balances, history, holdings), Orders/Trading (preview and submit via FIXML), Market data (quotes, clock, timesales, toplists,
    options chains, news), Member profile, Watchlists, and Utility status - returning JSON or XML. Ally Invest has since pivoted
    to managed and robo portfolios; the developer registration and documentation pages now resolve to marketing content, so
    this API is treated as retired and is listed humanURL-only. No downloadable OpenAPI/Swagger is published by Ally.
