  title: Stitch GraphQL API
  description: >-
    OpenAPI description of the single GraphQL endpoint exposed by the Stitch
    (stitch.money) payments and open-banking platform. All operations - Pay By
    Bank / LinkPay payment initiation, bank account verification, financial data,
    disbursements, refunds, and webhooks - are sent as GraphQL queries and
    mutations to POST /graphql. This document models the GraphQL transport; the
    GraphQL operations themselves are described in graphql/stitch-money-graphql.md
    and graphql/stitch-money-schema.graphql. Covers Stitch.money the fintech,
    distinct from any unrelated "Stitch" ETL product.
