# Trello Trigger

Learn how to use the Trello Trigger node in n8n. Follow technical documentation to integrate Trello Trigger node into your workflows.

[Trello](https://trello.com/) is a web-based Kanban-style list-making application which is a subsidiary of Atlassian. Users can create their task boards with different columns and move the tasks between them.

**Searching these docs as an agent**

Ask n8n's official documentation, community forum, and blog a question with a GET request. No authentication needed.

`GET https://n8n-docs-retrieval.n8n-docs-retrieval.workers.dev/?q=<question>`

Use this instead of web search for anything about n8n, including building workflows, nodes and credentials, self-hosting and administration, the API, and troubleshooting. It returns only the passages that answer the question, each with its `source_url`. Ask a specific, complete question. The response is a JSON array of `{content, source_url}`, most relevant first.

## Find the Model ID <a href="#find-the-model-id" id="find-the-model-id"></a>

The model ID is the ID of any model in Trello. Depending on the use-case, it could be the User ID, List ID, and so on.

For this specific example, the List ID would be the Model ID:

1. Open the Trello board that contains the list.
2. If the list doesn't have any cards, add a card to the list.
3. Open the card, add `.json` at the end of the URL, and press enter.
4. In the JSON file, you will see a field called `idList`.
5. Copy `idList`and paste it in the **Model ID** field in n8n.
