# Replace the set of annotation configurations assigned to a project

`PUT /v1/projects/{project_identifier}/annotation_configs`

Replace the project's entire set of assigned annotation configurations with the provided set. The server diffs the desired set against the current set: configs in the body but not assigned are added, and configs assigned but not in the body are removed. An empty array clears all assignments.

## Path parameters

- `project_identifier` string, required — The project identifier: either project ID or project name.

## Request body

- SetProjectAnnotationConfigsRequestBody
  - `annotation_config_ids` string[], required — The complete set of annotation configuration GlobalIDs that should be assigned to the project. Configs not in this list are unassigned; an empty list clears all assignments.

## Response `200`
