DBXML import endpoint to update data in OTM

Summary:

Dear All,

I am attempting to send a payload to OTM in order to update a few values on a shipment. However, I am encountering an "undefined error" in Postman.

Could someone kindly review the payload below and confirm whether it is correctly structured? Please note that I do not intend to use the Transmission Service URL for this request.

Thank you in advance for your support.

<?xml version="1.0" encoding="UTF-8"?><dbxml:xml2sql xmlns:dbxml="http://xmlns.oracle.com/apps/otm/DBXML">
