I would like to share a survey via an API call (as documented here: https://api.qualtrics.com/reference#share-survey) , but I'm having trouble getting the userid of the user to share with. When I do this manually via the web interface I search for the user by email, so I thought I could use the directory contacts search (https://api.qualtrics.com/reference#directory-contacts-search), but can't get it to work at all. (Python) code is: headers = { "x-api-token": self.apiToken, "content-type": "application/json", "Accept": "application/json" } tmp = requests.get("https://{0}.qualtrics.com/API/v3/directories".format(self.dataCenter),headers=headers) directoryId = tmp.json()['result']['elements'][0]['directoryId'] sharewith='XXXX@XXXX.com' filterstr = """ { "filterType": "email", "comparison": "eq", "value": "%s" }"""%sharewith filterjson = json.loads(filterstr) data = {"filter":filterjson} tmp = requests.post("https://{0}.qualtrics.com/API/v3/directories/{1}/contacts/search".format(self.dataCenter,directoryId),headers=headers,data=data) I get back error: "Error decoding json body: com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'filter': was expecting 'null', 'true', 'false' or NaN\\n at [Source: akka.util.ByteIterator$ByteArrayIterator$$anon$1@5720ef32; line: 1, column: 8]"
