Trello - Update Card

↩ Part of the Trello integration.

Description

Updates an existing Trello card (PUT /cards/{id}). This is also the node you use to move a card between lists and to archive it — Trello models both as an update, so there is no separate node for them.

The fields to change are given as a JSON object, which lets one node handle any editable card attribute without a form field per attribute.

Configuration

Field	Type	Required	Description
`credentials_id`	credentials	Yes	Trello credential
`card_id`	text	Yes	Card id
`fields`	JSON	Yes	Fields to update, e.g. `{"idList":"...","closed":true}`

card_id is resolved through dynamic variables ({{data.field}}). fields is not: it is parsed as JSON and sent as-is, so build any computed value in a previous node.

Credentials

This node requires a Trello credential (service type trello):

Field	Description
`api_key`	Trello API key
`token`	Token generated when authorizing that key

Commonly updated fields

Key	Effect
`idList`	Moves the card to that list (this is how you advance a board column)
`closed`	`true` archives the card, `false` restores it
`name`	Renames the card
`desc`	Replaces the description
`due`	Sets the due date (ISO)
`dueComplete`	`true` marks the due date as done
`idMembers`	Replaces the list of assigned members
`pos`	`top`, `bottom` or a number

Output

The updated card, as Trello returns it:

{
  "data": {
    "id": "66cd34ef56ab78cd90ef12ab",
    "name": "Order: ACME Inc.",
    "idList": "66ba98fe76dc54ba32fe10dc",
    "closed": false,
    "shortUrl": "https://trello.com/c/AbCdEfGh"
  },
  "_meta": {
    "moduleVersion": "1.0.0",
    "success": true,
    "id": "66cd34ef56ab78cd90ef12ab",
    "totalMs": 231
  }
}

Note the new idList: that is the confirmation the card actually moved.

Usage Example

Move the card to the “Done” list

{
  "credentials_id": "trello_ops",
  "card_id": "{{data.card_id}}",
  "fields": { "idList": "66ba98fe76dc54ba32fe10dc" }
}

Archive the card without deleting it

{
  "credentials_id": "trello_ops",
  "card_id": "{{data.card_id}}",
  "fields": { "closed": true }
}

Rename and set a due date

{
  "credentials_id": "trello_ops",
  "card_id": "{{data.card_id}}",
  "fields": {
    "name": "Order shipped",
    "due": "2026-08-20T09:00:00Z",
    "dueComplete": false
  }
}

Notes

If fields is not valid JSON, the node stops with a validation error before calling Trello.
Only the keys you send are changed; everything else keeps its current value.
idMembers replaces the assignee list, it does not add to it. Read the card first if you need to append.
Archiving (closed: true) is reversible; deleting is not.

Trello - Get Card — read the current values before updating.
Trello - Delete Card — permanent removal instead of archiving.
Trello - Create Card — create the card in the first place.
