You just need to load json and dump it to string and send it.

import json
valuetarget = "123"
payload = {
     'apikey': 'zbyc88srdi333d3dpq5lye48pgg1tfo1pnjvj65ld',
     'customfields': 
          json.dumps([{"code": "orderno", "value":valuetarget}])
}

You should escape the curly braces in the formatted string, like so:

f'[{{"code": "orderno", "value":"{valuetarget}"}}]'

But why not let requests format the string for you?

import requests

url = "https://www.stie.com/api/conversations/KJQ-CZHNR-985/fields"
valuetarget = "123"

# 'customfields' is now a list of dictionaries
payload = {'apikey': 'zbyc88srdi333d3dpq5lye48pgg1tfo1pnjvj65ld',
           'customfields': [{"code": "orderno", "value": valuetarget}]}
files = [

]
headers = {}

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

print(response.text)
