# Create a card

Creates a card in a list, with an optional description, due date, members and labels, and returns the card.

Note: Needs the `idList` of the list to create the card in.

## Set up

Use the first option your agent supports.

### API (official)

- Base URL: https://api.trello.com/1
- Endpoint: `POST /cards`
- Auth: an OAuth access token, sent as `Authorization: Bearer <token>`
- Docs: https://developer.atlassian.com/cloud/trello/rest/

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

## Rules

- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
