  title: Spinwheel Embedded Debt Solutions API
  description: >-
    Spinwheel's embedded credit and debt API. Connect a consumer, pull an
    Equifax-backed debt profile, refresh real-time liability balances and payoff
    quotes across credit cards and loans, originate bank-account-funded payments,
    and subscribe to webhook events. Most resources are scoped to a connected
    user identified by userId, the unique key used for accessing most Spinwheel
    APIs. Authentication uses a Spinwheel secret API key issued from the developer
    portal; the exact header scheme is gated behind the developer login and is
    not reconciled here - it is modeled as an HTTP bearer secret key.
