I am trying to use the toggl api.
I use Requests instead of Urllib2 for doing my GETs en POSTS. But i am stuck. 
payload = {
    "project":{
        "name":"Another Project",
        "billable":False,
        "workspace":{
            "Name":"jorrebor's workspace",
            "id":213272
        },
        "automatically_calculate_estimated_workhours":False
    }
}
url = "https://www.toggl.com/api/v6/projects.json"
r = requests.post(url, data=json.dumps(payload), auth=HTTPBasicAuth('
[email protected]', 'mypassword'))
Authentication seems to be fine, but the payload format probably isn't.
a curl command with the same parameters:
curl -v -u heremytoken:api_token -H "Content-type: application/json" -d "{\"project\":{\"billable\":true,\"workspace\":{\"id\":213272},\"name\":\"Another project\",\"automatically_calculate_estimated_workhours\":false}}" -X POST https://www.toggl.com/api/v6/projects.json
does work fine. 
What wrong with my payload? The response is get is: 
    ["Name can't be blank","Workspace can't be blank"]
which leads me to conclude that the authentication works but toggl cannot read my json object.
