Hi
swetakumar,
The reason why it appears you can submit a payload in a GET request in Postman is cos theres no context relative to the method selected in Postman whereas there is in soapui/soapui pro/readyapi!
The RFCs that describe http methods are vague in places but are clear on this point that they dont expect payloads to be submitted using GET. If you want to retrieve data and pass a payload the RFCs suggest using POST instead.
However, if you have the licensed version of soapui pro or readyapi you can make a config update to enable a payload field to appear for the GET method. There was another post recently where someone else asked the same question and one of the SmartBear staff respondef with the config entry change (i think it goes in the vmoptions file).
The config change does NOT work for open source soapui but does work for pro/readyapi version according to what the SB staff memner stated in the post. If you have a search you should be able to find it.
