UpdateValue error 400 with Python

Hi guys,


I'm trying to insert values to a attribute with Python using PI Web API and requests.


def post_data_by_attribute(self, parent_web_id, data):

  url = self._piWebAPI + "streamsets/" + parent_web_id + "/value"
   return, json = data)


data = [{ "WebId": WebId, "Value": {"Timestamp": "2017-10-25T14:00:00Z", "Value": "137"}}]

p = piConnection.post_data_by_attribute(WebId, data)



And I get <Error 400> as a response. The get requests work fine, only when I'm trying to post data that I'm struggling.


Any thoughts on what I may be doing wrong here?
