  title: Tink Account And Transactions Overview
  summary: List a user's accounts, read the balances of a chosen account, then list its transactions.
  description: >-
    A read-only financial overview built on a user access token. The workflow
    lists the bank accounts the user has consented to share, reads the booked
    and available balances of the first (or a supplied) account, and lists the
    transactions for that account within an optional booked-date range. Every
    step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
