Trello - Create Card

↩ Part of the Trello integration.

Description

Creates a card in a Trello list (POST /cards). It is the entry point of most Trello automations: a form is submitted, an order arrives or a ticket is opened, and a card appears in the right column of your board.

The destination list is identified by its id (id_list), never by its name. The title, description, due date and members accept dynamic variables from previous nodes.

Configuration

Field	Type	Required	Description
`credentials_id`	credentials	Yes	Trello credential
`id_list`	text	Yes	id of the list to create the card in
`name`	text	Yes	Card title
`desc`	textarea	No	Card description
`due`	text	No	Due date in ISO format (e.g. `2026-08-15T10:00:00Z`)
`id_members`	text	No	Member ids to assign, comma-separated
`pos`	text	No	Position: `top`, `bottom` or a number

id_list, name, desc, due and id_members are resolved through dynamic variables ({{data.field}}). pos is sent literally.

Credentials

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

Field	Description
`api_key`	Trello API key, from trello.com/app-key
`token`	Token generated when authorizing that key

Output

The node returns the card created by Trello, exactly as the API sends it:

{
  "data": {
    "id": "66cd34ef56ab78cd90ef12ab",
    "name": "Order: ACME Inc.",
    "desc": "3 units of SKU CAM-001",
    "due": "2026-08-15T10:00:00.000Z",
    "idList": "66ab12cd34ef56ab78cd90ef",
    "idBoard": "66aa11bb22cc33dd44ee55ff",
    "closed": false,
    "shortUrl": "https://trello.com/c/AbCdEfGh",
    "url": "https://trello.com/c/AbCdEfGh/12-order-acme-inc"
  },
  "_meta": {
    "moduleVersion": "1.0.0",
    "success": true,
    "id": "66cd34ef56ab78cd90ef12ab",
    "url": "https://trello.com/c/AbCdEfGh",
    "totalMs": 412
  }
}

The id is what you keep to comment on, update or move the card later.

Usage Example

Card from a form

{
  "credentials_id": "trello_ops",
  "id_list": "66ab12cd34ef56ab78cd90ef",
  "name": "Order: {{data.customer}}",
  "desc": "{{data.details}}"
}

Card with a due date, an assignee and top position

{
  "credentials_id": "trello_ops",
  "id_list": "66ab12cd34ef56ab78cd90ef",
  "name": "Incident #{{data.ticket_id}}",
  "desc": "Reported by {{data.email}}",
  "due": "{{data.deadline}}",
  "id_members": "5f8a1b2c3d4e5f6a7b8c9d0e",
  "pos": "top"
}

Notes

If id_list or name is empty, the node stops with a validation error and does not call Trello.
due must be an ISO date. Trello stores it in UTC and returns it as 2026-08-15T10:00:00.000Z.
id_members takes member ids, not usernames or emails.
A card whose list id belongs to a board your token cannot access fails with a 401/403 authentication error.

Trello - Update Card — move the card to another list or archive it.
Trello - Add Comment — post progress on the card you just created.
Trello - List Cards — check what is already in the list.
