How to find out List IDs? The JSON trick isn't working anymore

Stamina Overlook

When adding .json to the end of the URL, I just get the 404 page. How do I find out the list IDs?

It can happen when you do not have access to the card/board.

Update : self correction - you get a 401 instead.

Hi @Stamina Overlook 👋

Welcome to the Community! You should be able to get it via JSON:

Go to your Trello Board
Add ".json" to end of the URL
Format the JSON so it's readable (you can find a JSON viewer online)
Search for idBoard - this will list your full Board ID

URL should look like this:

https://trello.com/b/BaDyGlxp/<name of board>.json

You'll also find the list IDs in there under idList.

Option 2:

I dropped ".json" at the end of address in firefox and a pretty nice looking json display was rendered and the first item was "id", which worked for me.

I filtered "idBoard" and the only result was a "idBoardSouce" which was null. Maybe the "idBoard" has since changed to "id".

I hope this helps but if you have any other questions just ask away 😃

All the best,

Laura

Hello! Yes, I tried these methods, but like I said, adding .json to the end of the URL just sends me to the error 404 page. There's no JSON there - and nothing in the source, either. The source of the resulting page is just the source of the 404 page, with no hidden list IDs or anything.

Here, a screenshot that proves it:

An easier way, if you have generated a key and token for using the REST API, is to query the Get Lists on a Board endpoint:

https://api.trello.com/1/boards/{board_id}/lists?key={your_key}&token={your_token}

Example JSON response:

[
{
"id": "602786e91c69d30e45a9ccdb",
"name": "Backlog",
"closed": false,
"pos": 512,
"softLimit": null,
"idBoard": "602786e91c69d30e45a9ccd8",
"subscribed": false
},
{
"id": "60541af09b1c4353c8a3b29b",
"name": "Due in 4 days",
"closed": false,
"pos": 1024,
"softLimit": null,
"idBoard": "602786e91c69d30e45a9ccd8",
"subscribed": false
}
]

@Stamina Overlook No issue get the board. Looks like it is a Public board

You are correct that with the full url and a .json it gets a 404

Ahhhh, so I needed to take the name of the board out of the URL! Now it's all working, thank you so much
