This endpoint requires authentication. Include your Bearer token in the Authorization header.

​
Description

This endpoint allows linking an existing Asset to a release as a new track. The Asset’s data will be used as defaults, which can be overridden with the overrides parameter. Only releases in ‘draft’ or ‘rejected’ status can have Assets linked.

​

  method: 'POST',
  headers: {
    'Authorization': `Bearer ${token}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    "ref": "#/components/schemas/LinkAssetRequest"
  })
});
