Monday.com sub item start and end date to be pulled to the parent Timeline

Hi All, I am completely new to make.com. I need your help please.
I have a board on monday.com with lots of groups, items and sub items.
In the sub items we have start date and end date for the tasks.
I have created a timeline for the sub items with a formula but I need these dates or the formula to be pulled to the parent item Timeline.

I tried to build “Update Column Value…” and “Get an item’s column value” scenarios, but even with the help of Chat GPT its not working. I got “API not supporting sub items” warning and the latest is just not pulling any date… I dont know where to go with this. Can someone please help?

Thanks a lot.

Thanks for sharing the details, this is a really common issue with Monday.com’s API, since it doesn’t fully support subitems in the standard “Get/Update Item” modules on Make.

Although, it can still be done! The solution is to use a custom API call (via GraphQL) to pull the subitem start and end dates, calculate the overall range, and then update the parent timeline automatically.

Hi, thank you for your response. Is the GraphQL is an integration on Monday, or Make?
How should I start. Your help is appreciated.
