This article explain how to check that QMS API calls are sent correctly with Wireshark.
1. Install wireshark from www.wireshark.org. It is fine to just select all default settings for the install.
2. Launch wireshark and select the network interface that is used to communicate with the QlikView Server to start capturing traffic.
3. Send your API call. For example, in cURL to abort the task you would send something like this:curl --ntlm --user DOMAIN\Administrator:Password123! -H "Content-type:text/xml;charset=utf-8" -H "X-Service-Key:PmZzCHsUr58GBoLFDf2UHBmE4HYo+Obz" -H "SOAPACTION:http://ws.qliktech.com/QMS/11/IQMS/AbortTask" --user-agent "" --DATA @req2.xml http://QlikViewServer.domain.local:4799/QMS/Servicereq2.xml content:<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
</s:Envelope>4. In Wireshark, in the filter field write:
ip.addr == 172.16.16.100 && tcp.port == 4799
172.16.16.100 is the address of the QlikView Server. If you prefer to run Wireshark on the server side, input the IP address of the client from where you are sending the call instead.
5. Select the request going from the client to the server and check the request content to verify that all fields are filled in correctly.
