Trello API: Managing Cards and Lists

This guide demonstrates how to manage Trello cards and lists using the Trello API. Follow the steps below to move cards, apply labels, and archive lists.

Step 1: Retrieve the Card ID

To update or move a card, you must first retrieve its unique ID. Use the following GET request:

GET https://api.trello.com/1/boards/{boardID}/cards?key=YOUR_API_KEY&token=YOUR_ACCESS_TOKEN
        

Step 2: Move a Card to Another List

Once you have the Card ID, move it to another list by making a PUT request:

PUT https://api.trello.com/1/cards/{cardID}
Content-Type: application/json

{
  "idList": "{newListID}"
}
        

Step 3: Add a Label to a Card

Retrieve available labels and apply one to a card using a POST request:

POST https://api.trello.com/1/cards/{cardID}/idLabels
Content-Type: application/json

{
  "value": "{labelID}"
}
        

Step 4: Archive a List

To archive a list, send a PUT request setting closed to true:

PUT https://api.trello.com/1/lists/{listID}
Content-Type: application/json

{
  "closed": true
}
