# Get a return's cash-drawer pay-out

> Resolves the signed cash-drawer pay-out a processed return produced — a NEGATIVE integer-cent movement for a cash refund, or `null` for a non-cash / zero-valued one. This is the figure the back-office reconciles the register against. 404s when no return carries the given id.

  description: >-
    The Solya POS backend HTTP surface. Every documented operation is
    agent-ready: it carries an `operationId`, an agent-facing `description`, the
    `pos.*` scopes it enforces (`x-required-permissions`) and an `x-agent-tier`.
    Success responses return the payload as raw JSON; failures return the
    `ErrorResponse` envelope (`{ error: { code, message, statusCode } }`).
