Python 3.x - Web Server - extract json body from POST request - json

Question

I am sending a Post request with a json body to a server but can not extract the json file when it arrives. I have does exhaustive searches but to no avail. I have provided both client and server scripts to illustrate what is happening.
All I need is to extract the json portion at the end of the received string so I can analyze the request and return the appropriate data.
I'm sure it's simple but I can't seem to find the answer. Any direction would be appreciated
***
CLIENT: script to test Server
import json
import requests
def info_send():
url = 'http:1234abcd.ngrok.io'
payload = {
'command': '["command", "status", "off", None]',
'userID': 'userID string',
'status': 'current status',
}
requests.post(url, data=json.dumps(payload))
info_send()
***
SERVER: receives json POST request
HOST, PORT = '', 5000
listen_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
listen_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
listen_socket.bind((HOST, PORT))
listen_socket.listen(1)
print('Listening on port %s' % PORT)
while True:
client_connection, client_address = listen_socket.accept()
request = client_connection.recv(1024).decode('utf-8')
print(request)

This is what is printed at the server
