# Update a card

`PATCH /api/v2/projects/{projectId}/cards/{cardId}`

## Request

- Base URL: `https://davinci-app.com`
- URL: `https://davinci-app.com/api/v2/projects/{projectId}/cards/{cardId}`
- Auth: HTTP bearer

Updates project-global card fields and appends field-history events.
Changing `isOpen` never changes any team workflow placement.

## Headers

- `If-Match` string

## Request body

- UpdateCardRequest
  - `name` string: Sanitized by the server to a resource name of at most 255 characters.
  - `description` string, nullable
  - `resolution` string, nullable
  - `isOpen` boolean
  - `deadline` string, date-time, nullable
  - `effort` integer, nullable
  - `expectedHistoryHeadId` string, uuid, nullable: Latest committed card-history row ID; null only before a card has history.

## Response `200`

Updated card.

## Other responses

- `400`: Malformed request parameters or body. Agile requests may return `INVALID_PAGINATION` or `INVALID_IDEMPOTENCY_KEY`.
- `401`: No credential was supplied, or the supplied credential is malformed, expired, or revoked. A credential that is present but unusable is never downgraded to an anonymous request.
- `403`: Authenticated but not authorized. Either the acting user lacks the required resource permission, the key's scope ceiling excludes it, or the endpoint rejects this credential type (`CREDENTIAL_NOT_PERMITTED`).
- `404`: The resource does not exist in the parent named by the path, or is hidden from the caller. Absence and privacy denial are deliberately indistinguishable so project, organization, and private-team existence cannot be probed.
- `409`: The supplied `If-Match`, `expectedHistoryHeadId`, or `expectedHistoryHeadIds` no longer matches committed card history. Error code is `CARD_HISTORY_CONFLICT`; `error.details` includes the expected head, current head and sequence, plus recent card activity. No part of the requested card mutation is applied.
- `429`: Request rate exceeded, either globally or for this key.
- `500`: Unexpected server error.
