PUT request via postman works, but via python requests not

Question

When I send PUT request via postman everything is ok, but when I copy code from postman to python I get this:

{"code": 50035, "errors": {"_errors": [{"code": "CONTENT_TYPE_INVALID", "message": "Expected "Content-Type" header to be one of {'application/json'}."}]}, "message": "Invalid Form Body"}

the code:

url = "https://discord.com/api/v9/guilds/860859559908474900/premium/subscriptions"

payload={'user_premium_guild_subscription_slot_ids': '853228009795223572'}
files=[

]
headers = {
  'authorization': 'here token',
  'Cookie': '__dcfduid=c5cbabf10a8344558c8c4b90a6e306e2'
}

response = requests.request("PUT", url, headers=headers, data=payload, files=files)

print(response.text)

if I add ‘content-type’ : ‘application/json’ to headers, I get this:

{"message": "400: Bad Request", "code": 0}

Either use json= instead of data= or add the Content-Type header with value application/json as the server tells you.

Also check the Authorization header, mostly there’s a prefix which mentions what auth to use e.g.:

Authorization: Basic base64-encoded(user:pass)
Authorization: Bearer token
Authorization: Token token

and make sure the files parameter is actually allowed to be empty by the API and if not, try removing it.

Then there’s __dcfduid cookie you provide. Some cookies tend to be dynamic as in the value changes between requests. Try then establishing the session and do the login part within it:

import requests as r
ses = r.Session()
resp = ses.post(<login to the API>)
print(resp.text)
ses.put(
    url="https://discord.com/api/v9/guilds/860859559908474900/premium/subscriptions",
    headers={
        'Authorization': 'here token',
        # cookies are in the ses object
    },
    json={
        'user_premium_guild_subscription_slot_ids': '853228009795223572'
    },
    # if required
    files=[...]
