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.
