Get report data from API (DAU/MAU/New Users)

I can get a result after post request this URL - https://dashboard.unity3d.com/app/analytics/graph_service/get_graph_data.json

But I do not know how I can update x_xsrf_token and cookie_token because I think they can be expired after time

Example code

 import requests
 
 url = "https://dashboard.unity3d.com/app/analytics/graph_service/get_graph_data.json"
 
 x_xsrf_token = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa="
 cookie_token = 'token=aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'
 
 payload = "{\"app_id\":\"11111111-1111-1111-1111-11111111\",\"cohort_metric_string\":[\"[{\\\"metric_name\\\":\\\"MAU\\\",\\\"metric\\\":\\\"\\\",\\\"cohort_id\\\":\\\"\\\",\\\"cohort_name\\\":\\\"All Current Users\\\",\\\"graph_id\\\":\\\"MAU\\\",\\\"checkSum\\\":0,\\\"unit\\\":\\\"\\\",\\\"color\\\":\\\"\\\",\\\"series\\\":[],\\\"type\\\":\\\"metric\\\",\\\"segment_name\\\":\\\"\\\",\\\"segment_type\\\":\\\"\\\"},{\\\"metric_name\\\":\\\"DAU\\\",\\\"metric\\\":\\\"\\\",\\\"cohort_id\\\":\\\"\\\",\\\"cohort_name\\\":\\\"All Current Users\\\",\\\"graph_id\\\":\\\"DAU\\\",\\\"checkSum\\\":0,\\\"unit\\\":\\\"\\\",\\\"color\\\":\\\"\\\",\\\"series\\\":[],\\\"type\\\":\\\"metric\\\",\\\"segment_name\\\":\\\"\\\",\\\"segment_type\\\":\\\"\\\"},{\\\"metric_name\\\":\\\"New Users\\\",\\\"metric\\\":\\\"\\\",\\\"cohort_id\\\":\\\"\\\",\\\"cohort_name\\\":\\\"All Current Users\\\",\\\"graph_id\\\":\\\"New Users\\\",\\\"checkSum\\\":0,\\\"unit\\\":\\\"\\\",\\\"color\\\":\\\"\\\",\\\"series\\\":[],\\\"type\\\":\\\"metric\\\",\\\"segment_name\\\":\\\"\\\",\\\"segment_type\\\":\\\"\\\"}]\"],\"datepicker_start\":\"04/01/2021\",\"datepicker_end\":\"05/20/2021\"}"
 headers = {
   'X-XSRF-TOKEN': f"{x_xsrf_token}",
   'Content-Type': 'application/json;charset=UTF-8',
   'Cookie': f"{cookie_token}"
 }
 
 response = requests.request("POST", url, headers=headers, data=payload)
 
 print(response.text)
