It is legal (in some cases) to send a receive request with the json data contained in the body. But it soapuihides the "body" subwindow, where I can insert the json string, so only the key-value pair menu is available. Is there a workaround to send a request with the body to soapui?
soapui
You can add json, select application / json as the type of Media, as shown below. I am using soapui release 4.5.1, the free version on Linux.
Is this what you are looking for?
