    Why it is in this group

    • The name "submit_listing" says "submit": a word for a change.
    Description, as the server wrote it
    Submit the user's own product to the marketplace. Requires the creator's API key (duk_..., from the Creator dashboard -> API keys; never guess one). Free. Every submission is screened and waits for human owner approval; nothing is published automatically. Only submit real products the user owns, with accurate claims.
