Python request returning IN-QUEUE status after posting

I've been trying to learn and understand how http requests are being made between the clients and server, so I've decided to test out by sending a simple post request to geeksforgeeks' online IDE. Using requests, I am able to get a response of the following, {'status': 'SUCCESS', 'sid': 'df1acaffefacb25dfef2c7cf66022925'} using the following code,

import requests
import time
url = "https://ide.geeksforgeeks.org/main.php"
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20100101 Firefox/20.0'}

code = """
print("hello")
"""

data = {
    'lang':'Python3',
    'code': code,
    'input':'0',
    'save':'false'
}

r = requests.post(url, data = data, headers = headers)
print(r.json())

Next, I know that i have to resend back the sid parameter to https://ide.geeksforgeeks.org/submissionResult.php in order to get a successful response. However, when i entered the following code,

requesttype = {
    'sid': r.json()['sid'] ,
    'requestType': 'fetchResults'
}

headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20100101 Firefox/20.0'}

url2 = "https://ide.geeksforgeeks.org/submissionResult.php"

session = requests.Session()
outcome = session.post(url2, data = requesttype, headers = headers)

It returns {'status': 'IN-QUEUE'}. Upon analyzing the networks tab in my browser, it seems as though the online IDE has a queue system that will only parse your incoming request server sided through a queue-like system. Hence I would like to know how to obtain a success response by "communicating" with their queue system.

A successful response looks like this,

{"valid":"1","output":"testing\n","time":"0.02","compResult":"S","memory":"0.125","hash":"79c7a40c6f6b36f1dfc23119f27ba66e_Tester_U16","status":"SUCCESS"}

My hunch is telling me that the website is detecting me as a bot and I should use something else like selenium perhaps.
