cXML PunchOut Carts

PunchOutOrderMessage

The cXML PunchOutOrderMessage document contains the shopping cart items the shopper checked out from the eCommerce site. It is possible that the document will not contain any items if the shopper is returning from the eCommerce site with an empty cart.

Cart Transmission

The PunchOutOrderMessage must be sent back to the eProcurement system from the shoppers web browser. Upon submitting the cart via an HTML form, the user will return to the eProcurement system and no longer be on the suppliers site.

The HTML below consists of a form that is automatically submitted via JavaScript. Typically when clicking the "Checkout" button on the eCommerce site, users are redirected to a page with a loading message and the HTML <form>.

The example HTML below contains 2 variables that must be replaced with HTML escaped values:
buyer_form_post_url - the BuyerFormPost/URL from the PunchOutSetupRequest
xml - the cXML PunchOutOrderMessage document

<form id="cxml_form" method="POST" action="{{buyer_form_post_url}}" enctype="application/x-www-form-urlencoded">
  <input type="hidden" name="cXML-urlencoded" value="{{xml}}">
</form>
<script type="text/javascript">document.getElementById('cxml_form').submit()</script>

Credentials

The Header element is typically ignored by eProcurement applications when processing PunchOutOrderMessage documents. Instead, the BuyerCookie can be used to identify the user/session that was used to PunchOut.

BuyerCookie

The BuyerCookie element should contain the same value that was in the BuyerCookie element in the PunchOutSetupRequest for the current user.

PunchOutOrderMessageHeader

The PunchOutOrderMessageHeader element contains an operationAllowed attribute that should be set to "create" unless Edit/Inspect functionality is supported by the ecommerce site. The element should also contain a Total element with the sum of the cart items, shipping, and tax. Tax and Shipping elements can optionally be included if these amounts are known at the time the cart is sent back to the e-procurement system.

<PunchOutOrderMessageHeader operationAllowed="create">
  <Total>
    <Money currency="USD">33.43</Money>
  </Total>
  <Shipping>
    <Money currency="USD">4.50</Money>
    <Description xml:lang="en-US">USPS</Description>
  </Shipping>
  <Tax>
    <Money currency="USD">1.34</Money>
    <Description xml:lang="en-US">Sales Tax</Description>
  </Tax>
</PunchOutOrderMessageHeader>

ItemDetail/UnitOfMeasure

The Unit of Measure (UOM) is the marketed units by which an item will be delivered when purchased and to which the unit price refers. Unit prices should be in reference to 1 UOM. Some e-procurement systems require the code to be one of a pre-defined list of UOM’s.
