API connection Noobie

Im using python and i wanted to know why this is not correct?

i think my parameters are wrong but could someone point me to the right direction?

import requests

params = {
'start': '{2019-07-01T00:00:00.000Z}',
'end': '{2019-07-02T00:00:00.000Z}'
}

Organizations = 'asdad'
Organization_ID='asdasdasdas'
APIkey='asdasdadasdasda'



request_url = 'https://stats.unityads.unity3d.com/{}/:{}/reports/acquisitions?splitBy=campaignSet,country&fields=timestamp,campaignSet,country,clicks,installs,spend&apikey={}'.format(Organizations,Organization_ID,APIkey)

res = requests.request('GET', request_url, params=params)

res.status_code
