# Listing sold

> **We send this to your URL**, once we've set a webhook up for your key: contact us with its name and your URL, and we give you a signing secret once. Setup, checking the signature and retries: [Webhooks](/partner-api/webhooks). Someone bought one of your listings, wherever you listed the card. It doesn't say who bought it. Every webhook on the account gets it.

`order` is the same object List orders returns for a sale, with `type: "listing_sale"`.



## OpenAPI

````yaml /partner-api/openapi.yaml webhook listing.sold
openapi: 3.1.0
info:
  title: CatchBack Partner API
  version: 1.0.0
  summary: Open packs, trade cards, read card data and ship vaulted cards.
  description: >-
    The Partner API acts on one CatchBack account with its real CatchCoins
    balance. Several

    operations here move money or data, so read
    [Idempotency](/partner-api/idempotency) before

    you call them.


    Error bodies are JSON with a human-readable `error` and, where you might
    branch on it, a

    machine-readable `code`. Branch on the status and the `code`, because the
    `error` text can

    change. New fields can be added to any response.
