One request fails, but others don't; it also succeeds in terminal

[ErikDB87]

I checked a lot of trouble-shoot topics, but didn't find what might be wrong here...

I'm going off this API documentation: https://kritsel.github.io/tado-openapispec-v2/swagger

This code:

import requests
import json


url1 = "https://my.tado.com/api/v2/homes/[myzone]/zones/2/schedule/activeTimeTable"
url2 = "https://my.tado.com/api/v2/homes/[myzone]/zones/2/details"

token = "[mytoken]"

headers = {
    'Authorization': "Bearer "+token,
    'User-Agent': 'python/libtado',
}

data1 = {"id": 1}
data2 = {"name": "Eetkamer"}


timeout = 15

r1 = requests.put(url1, headers=headers, json=data1, timeout=timeout)
r2 = requests.put(url2, headers=headers, json=data2, timeout=timeout)

print("###################")

print(r1)
print("-------------------")
r1.status_code
print("-------------------")
print(r1)

print("###################")

print(r2)
print("-------------------")
r2.status_code
print("-------------------")
print(r2)

print("###################")

... results in this output:

PS C:\Git\requests-set-schedule-tado> python requests-test.py
###################
<Response [403]>
-------------------
-------------------
<Response [403]>
###################
<Response [200]>
-------------------
-------------------
<Response [200]>
###################

But when I make that HTTP request to https://my.tado.com/api/v2/homes/[myzone]/zones/2/schedule/activeTimeTable in PowerShell, the response is 200...:

PS C:\Git\requests-set-schedule-tado> Invoke-WebRequest -UseBasicParsing -Uri "https://my.tado.com/api/v2/homes/[myzone]/zones/2/schedule/activeTimetable" `

InputFields       : {}
Links             : {}
RawContentLength  : 27
RelationLink      : {}

Could someone guide me to a solution?

Thanks in advance!
