Simple update of column value for an item doesn't work


I try to update a column value for an item but I have a strange error. My column type is numeric, here the code I use (python) :

import requests
token = "xxx"

headers = {
        'Content-Type': 'application/json',
        'Accept': 'application/json',
        'Authorization': token

url = ""

mutation_query = """
mutation {
        board_id: 123, 
        item_id: 123, 
        column_id: "numbers53", 
        value:"\"3\"") {
response =
        json={"query": mutation_query}, 

And here the response I get :

{'errors': [{'message': 'Parse error on "3" (INT) at [7, 16]', 'locations': [{'line': 7, 'column': 16}]}], 'account_id': xxx}

Is the value I send to the API correctly formatted ?

Hi @alexmat,

I do not have experience with python, but the values you supply in the mutation for board_id and item_id do not look like real id’s. Is that on purpose, just to show here? The board_id can we derived from the address bar of your browser and the item_id can be found in a column named PulseID

Have fun,

Yes of course I put fake ids on purpose for the example

Hi Alex,

The Phyton code generated from a working Postman request is:

import requests

url = “

payload = {‘query’: ‘mutation {change_column_value(board_id: 524382854, item_id: 524382857, column_id: numbers, value:"\“3\”") {id}}’}
files = [

headers = {
‘Authorization’: ‘my_secret_monday_token’


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

Hope this helps a bit. Postman is wonderful for testing :slight_smile:
