If you’re on a recent 8.0 version, you can use [system.net.httpClient()](https://docs.inductiveautomation.com/display/DOC80/system.net.httpClient):  
`system.net.httpClient().post(url=url, params=parameters, headers=header).json`

That said, using `system.net.httpPost` should still work, but you’ll have to encode your URL parameters manually; the `postData` parameter the function accepts indicates data to send _in the request body_, not as URL parameters, which it looks like you’re trying to do. You’ll need to manually append the parameters to the API URL you’re retrieving; something like:

```auto
import urllib

url = "http://192.168.1.598/api"
url += "?"
postParams = # some dictionary
header = #some dictionary

for k, v in postParams.items():
	url += urllib.quote(k) + "=" + urllib.quote(v)

system.net.httpPost(url, headerValues=header)

```

Yes i actually did not define the parameters for system.net.httpPost() as defined.  
Now its working fine.  
I ll also try system.net.httpClient().  
Thanks for the help
