Using in a case result in another case as a parameter

[m_essaid]

Hi,

I'm a TestComplete user and don't know anything about REST API testing, so I'm sorry if my question does not make sense,

I have 2 resources, each return JSON datas. But I need to use part of the result of the first resource (a guid) to use it as a parameter in the second resource.

Is this possible with SoapUI ?

Please note that I have TestComplete, so I could use script and automate whatever I want (for example I could browse the JSON with some script).

Thank you,

Mehdi
