Edwin,
What is the xml you are sending and how the headers are configured?
Are you sending a get or post with postman?
After setting the SOAP Action in the headers and sending the post, i am receiving this
<?xml version="1.0" encoding="utf-8"?>
<dbCentral_response xmlns="Database">
<ServiceResults>
<Result>
<ResultAction>insert</ResultAction>
<ResultTable>central</ResultTable>
<ResultRecordId>CEN_REFNUM=335292</ResultRecordId>
<ResultDescription>success</ResultDescription>
</Result>
</ServiceResults>
</dbCentral_response>
If i do a get i receive this
<?xml version="1.0" encoding="utf-8"?>
<dbCentral_response xmlns="Database">
<MainLeadID>0</MainLeadID>
</dbCentral_response>
