What Credentials Are Used For cXML Invoice Transmission?

cXML invoices match the credentials used during cXML PO transmission. During PO transmission suppliers provide a Sender Credential and Shared Secret. The PO Sender Credential and Shared Secret will be used to verify the suppliers identity during cXML invoice transmission.

Please see the PO example below:

 <Sender>
      <Credential domain="DUNS">
          <Identity>123456</Identity>
          <SharedSecret>SUPPSHARED123</SharedSecret>
      </Credential>
      <UserAgent>BuyerQuest</UserAgent>
  </Sender>

Thus the invoice credentials would match the below: 

<Header>
    <From>
        <Credential domain="DUNS">
            <Identity>123456</Identity>
            <SharedSecret>SUPPSHARED123</SharedSecret>
        </Credential>
    </From>
    <To>
       <Credential domain="DUNS">
           <Identity>SENDER123</Identity>
       </Credential>
     </To>
   <Sender>
      <Credential domain="DUNS">
          <Identity>123456</Identity>
          <SharedSecret>SUPPSHARED123</SharedSecret>
      </Credential>
      <UserAgent>BuyerQuest</UserAgent>
  </Sender>
</Header>
