  version: '1.0'
  description: >-
    WISK's public sales-upload API lets POS providers and integration partners
    push sales line items into a customer's WISK account so that sales can be
    reconciled against inventory. A partner submits an array of sales lines via
    a single POST operation. WISK provisions each partner with a venue unique
    identifier that is supplied in the request header to route the data to the
    correct venue/account.


    This specification was generated from WISK's public documentation. The
    request path, JSON body structure, and field definitions are taken
    verbatim from the public "Public Sales upload" guide; the exact request
    header name is provisioned per-partner by WISK and is therefore modeled
    generically.

        Push an array of point-of-sale sales line items into a WISK venue
        account. Each element of the array represents a single sales line from
        a receipt; a receipt that contains multiple distinct items produces one
        array element per item. The destination venue is identified by the
        venue unique identifier header that WISK provisions for the partner.

        Venue unique identifier provisioned by WISK for the partner. The public
