Comment on a card

Comment on a card

Adds a comment with the text you pass to a card and returns the comment action.

Set up

Use the first option your agent supports.

API (official)

• Base URL: https://api.trello.com/1
• Endpoint: POST /cards/{id}/actions/comments
• 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.
