Update a task column using API

I am trying to update a ticket column. I am getting a 200 response for the code below but it does not reflect on the ticket itself. What gives?

apiUrl = "https://api.monday.com/v2"
headers = {"Authorization" : apiKey}

query= 'mutation {change_simple_column_value(item_id: 	3601557877, board_id: 3543199429, column_id: "Triage Score", value: "99") }'
data = {'query' : query}

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

Hi @mhariri,

Welcome to the community! We hope you like it here.

It looks like you may have passed in a column name instead of an ID.

You can verify the column ID by turning on Developer Mode, which exposes column IDs and other useful IDs for your queries. This video explains how to turn on Developer Mode.

With Developer Mode on, column IDs will become visible when you click the three dot menu next to the column name.

I hope this helps! Please let me know if you have any more questions.
