# Comment on a card

`POST /cards/{card}/comments`

## Request

- Base URL: `https://api.yokka.ai/api/v1`
- URL: `https://api.yokka.ai/api/v1/cards/{card}/comments`
- Auth: HTTP bearer

Leave a comment on a card: answer something the human wrote, note a decision, or leave context for whoever picks it up next. Unlike request_input it doesn't flag the card for the human or move it. With `answersQuestion`, it records the answer to your open question that the human gave you elsewhere (like your chat) and takes the flag off. Use report_progress for milestones on work you hold.

Needs a read-and-write token. Same as the MCP tool `comment_card`.

## Path parameters

- `card` string, required: The card's ref, like "GS-12".

## Headers

- `X-Client-Name` string
- `Idempotency-Key` string

## Request body

- object
  - `message` string, required: The comment. Markdown is fine.
  - `answersQuestion` boolean: Optional: true when the comment is the human's answer to your open request_input question, given outside the board. Closes the question, so the card stops waiting on them.

## Response `201`

Created. The tool's result.

- object
  - `ref` string, required
  - `cursor` string, required
  - `closed_question` boolean, required

## Other responses

- `400`: The arguments aren't valid, or the change isn't possible as asked.
- `401`: The token is missing, invalid, revoked or expired.
- `403`: The token can't do this, or a plan or board limit was reached.
- `404`: Something it names wasn't found, or isn't visible to this token.
- `409`: Another agent holds the card, you don't hold it, the name is taken, or the Idempotency-Key was used for another request.
- `413`: The request body is too large.
- `429`: Too many calls: retry after `Retry-After` seconds.
