# Trello

> A Trello app for boards, lists, cards, labels, checklists, and member assignments via your connected account.

Use this app when you want to create or update Trello work items from a workflow. You can also look up boards, lists, cards, and checklist details before making changes.

## Configuration

| Option | Required | Description |
| - | - | - |
| Name | No | Label for the step in the workflow canvas. |
| Authentication | Yes | The connected Trello account to use for this step. |
| Action | Yes | The Trello action to perform (for example Create board, Get board, Create list, List board lists). |
| Arguments | Yes | Per-action form fields generated from the action's schema. Each text field has an **Insert Variable** button for injecting `{{placeholder}}` values. A **Raw JSON** tab is available for advanced usage. |
| When the step fails | No | Controls whether the workflow should **Terminate Workflow** or **Continue** if this step fails. |

Before you configure this step, connect Trello in **Integrations** for your workspace using the sign-in flow. If no active connection is available, the step shows a warning with a link to **Integrations** instead of the account selector.

## Arguments form

When you select an action, the **Arguments** section renders a form driven by the action's input schema. Fields that refer to existing records include dropdown pickers.

Switch to the **Raw JSON** tab when you prefer to write the full arguments object by hand. Changes in either tab stay in sync.

## Common actions

| Action | Description |
| - | - |
| **Create board** | Creates a new Trello board. |
| **Get board** | Fetches details for a board by ID. |
| **Create list** | Creates a new list on a board. |
| **List board lists** | Lists the lists on a board. |
| **Rename list** | Updates the name of a list. |
| **Create card** | Creates a new card in a list. |
| **Get card** | Fetches a card by ID. |
| **List cards** | Lists the cards in a list. |
| **Add comment** | Adds a comment to a card. |
| **Create checklist** | Creates a new checklist on a card or board. |
| **List checklists** | Lists the checklists on a card. |
| **Add check item** | Adds a new check item to a checklist. |
| **Update check item state** | Updates a check item's completion state. |
| **Create label** | Creates a new label on a board. |
| **Add label** | Adds an existing label to a card. |

Destructive actions, such as deleting records, are not available in the workflow action picker.

## Output

This step stores the Trello response as the step output. The shape of the response depends on the action.

Use the full output reference in later steps:

```text theme={null}
{{STEP_IDENTIFIER.output}}
```

## Example

1. Open **Integrations** and connect Trello if you have not already done that.
2. Add a **Trello** step to your workflow.
3. Select a connected account in **Authentication**.
4. Choose **Create board** in **Action**.
5. Fill in the required fields. Use **Insert Variable** to reference an earlier step's output for any field value.
6. Click **Run** in the step header to test the action, then review the returned payload in **Output**.

## Use cases

### Create a task card

1. Create list
2. Create card
3. Add label

2. Add check item
3. Update check item state

## Notes

* This step depends on a connected Trello integration in your workspace.
* The workflow action picker shows a curated set of actions. Agents with the Trello tool can use more of them.
* The sign-in screen may show third-party authorization branding.

## Using Trello as an Agent Tool

You can also add Trello as a tool in the **Agent Editor**. Open the agent, click **Add tool**, and select **Trello**. In the tool settings panel, choose the connected account the agent should use. The agent calls Trello actions when they are relevant to the conversation.
