Post request payload in python

I'm trying to write a python script to get the tracking info from this page: https://www.purolator.com/en/app-tracker.page. Using F12 in Chrome, I got the header and the request payload, no form data just request payload. The tracking number I'm trying is: GRH000241377

Here's my code:

 header = {
        'authority': 'api.purolator.com',
        'method': 'POST',
        'path': '/tracker/puro/json/shipment/search',
        'scheme': 'https',
        'accept': 'application/vnd.puro.shipment.trackingevent+json',
        'accept-encoding': 'gzip, deflate, br',
        'accept-language': 'en-CA',
        'content-length': '90',
        'content-type': 'application/vnd.puro.shipment.trackingevent+json',
        'origin': 'https://www.purolator.com',
        'referer': 'https://www.purolator.com/en/app-tracker.page?pin=GRH000241377&sdate=2019-12-09',
        'sec-fetch-mode': 'cors',
        'sec-fetch-site': 'same-site',
        'user-agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) '
                      'Chrome/79.0.3945.117 Safari/537.36'
    }

    data = {
        'pins':'[{"pin":"GRH000241377","sequenceID":1}]',
        'searchOptions':'{"includeReference":true}'
    }


    url = "https://www.purolator.com/en/app-tracker.page"
    response = requests.post(url, headers=header, json=data)
    res_json = response.json()

Response code is 200 but when i print the response.text i get the same page without any result, and if try to get response.json() i got next error, I'm assuming that error is because i have no json in the response

'Error occurred : \n Error Message: Expecting value: line 1 column 1 (char 0)'

Presumably error is on data or header construction but can't figure out the problem. Any idea? Thanks

Here are the response headers:

I hope this helps.

Python code:

import requests

header = {
  'authority': 'api.purolator.com',
  'method': 'POST',
  'path': '/tracker/puro/json/shipment/search',
  'scheme': 'https',
  'accept': 'application/vnd.puro.shipment.trackingevent+json',
  'accept-encoding': 'gzip, deflate, br',
  'accept-language': 'en-CA',
  'content-length': '90',
  'content-type': 'application/vnd.puro.shipment.trackingevent+json',
  'origin': 'https://www.purolator.com',
  'referer': 'https://www.purolator.com/en/app-tracker.page?pin=GRH000241377&sdate=2019-12-09',
  'sec-fetch-mode': 'cors',
  'sec-fetch-site': 'same-site',
  'user-agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.117 Safari/537.36'
}

data = {"trackingNumbers":[{"trackingNumber":"GRH000241377", "type":"Unspecified","sequenceID":1}]}

url = "https://api.purolator.com/tracker/puro/json/shipment/trackingEvent/summary/search"
response = requests.post(url, headers=header, json=data)
res_json = response.json()

print (res_json)

Output:

{"trackingResults": [{"searchStatus": "Found", "foundBy": "Pin", "searchCriteria": {"trackingNumber": "GRH000241377", "type": "Unspecified", "sequenceID": 1}, ..., "isStateBehind": False}
