Looking at the documentation found here: [https://support.inductiveautomation.com/usermanuals/ignition/index.html?system\_net\_httppost.htm](https://support.inductiveautomation.com/usermanuals/ignition/index.html?system_net_httppost.htm), I don’t understand the postData parameter.  
Is it expecting a certain string format?

I need to pass data to the server via JSON.  
Something like “{‘Id’: 2, ‘Desc’:‘Testing’}”

[code]dict = {‘Id’: 2, ‘Desc’:‘Testing’}

postData = system.util.jsonEncode(dict)[/code]

Thank you. ![:thumb_left:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/e26afb081ddde6df016df6ee49159cf56aaca688.gif ":thumb\_left:")  
It turns out jsonEncode does a better job encoding json than what I had.  
The single quote in json was my problem. Needs to be double quote otherwise not valid.

So jsonEncode does all that behind the scene and encodes the dictionary object to:  
{“Id”: 2, “Desc”:“Testing”}
