Error 424 when trying to add an IP address via REST API

[PurpleShirt]

Hi everyone

I am trying to use the REST API to add IP addresses on our Firewall. 

I have this python code: 

import os
import requests
import urllib3
import getpass

urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

baseURL = "REDACTED URL"
apiURL = "/api/v2/cmdb/firewall/address"
token = "REDACTED TOKEN"

headers = {'Authorization':'Bearer ' + token,}

params = {
   "datasource":1,
   "vdom": "root"
   }

def createNewIpAddressData(ipAddress):
   data = {
      "name":"ext-" + ipAddress,
      "subnet":ipAddress + "/32",
      "comment": "New IP",
      "color":"0"
   }
   return data

def addNewIpAddress(postData):
    try:
      r = requests.post(baseURL + apiURL, headers=headers, params=params, verify=False, data=postData, timeout=5)
    except requests.exceptions.Timeout:
      print("Timeout!")
      return None
    
    if r.status_code != 200:
       print("Error code:{}".format(r.status_code))
       print(r.content)
       return None
    
    return r.json

result = addNewIpAddress(createNewIpAddressData("5.153.183.99"))
print (str(result))

When I execute this, I receive this error with the htpp_status 424: 

 "http_method":"POST",\n  "revision":"REDACTED",\n  "revision_changed":false,\n  "status":"error",\n  "http_status":424,\n  "vdom":"root",\n  "path":"firewall",\n  "name":"address",\n  "serial":"REDACTED",\n  "version":"v7.0.12",\n  "build":523\n

 I've used the API code from my FortiGate and according to the documentation, it says that it misses some dependencies, but I can't figure out what it misses. 

Can someone point me in the right direction? 

Thanks.

Ok I found the issue. I had to encode it to json before passing it to the post request. 

Here the updated code, if someone needs it. 

import os
import requests
import urllib3
import getpass
import json

urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

baseURL = "REDACTED"
apiURL = "/api/v2/cmdb/firewall/address"
token = "REDACTED"

headers = {'Authorization':'Bearer ' + token,}

params = {
   "datasource":1,
   "vdom": "root"
   }

def createNewIpAddressData(ipAddress):
   data = [{
      "name":"ext-" + ipAddress,
      "subnet":ipAddress + "/32",
      "comment": "New IP",
      "color":"0"
   }]
   jsondata = json.dumps(data)
   return jsondata

def addNewIpAddress(postData):
    try:
      r = requests.post(baseURL + apiURL, headers=headers, params=params, verify=False, data=postData, timeout=5)
    except requests.exceptions.Timeout:
      print("Timeout!")
      return None
    
    if r.status_code != 200:
       print("Error code:{}".format(r.status_code))
       print(r.content)
       return None
    
    return r.json

result = addNewIpAddress(createNewIpAddressData("5.153.183.99"))
print (str(result))
