# Remove a design-object link

`DELETE /api/v2/projects/{projectId}/cards/{cardId}/object-links/{linkId}`

## Request

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

Removes the reference and records it in card history.

## Headers

- `If-Match` string

## Response `204`

Object link removed.

## Other responses

- `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.

## Changes

- **2026-09-15** (v2) `67c8b8616dbb`: 1 info
  - endpoint added
