# Bulk acknowledge policy changes
URL: https://backworkhealth.com/docs/api/bulkAcknowledgeChanges

Acknowledge up to 200 policy changes at once.

**Endpoint:** `POST /api/v1/compliance/ack/bulk`

**Availability:** Live in production.

**Authentication:** API key in `Authorization: Bearer <key>` with the `write` scope.

Acknowledge up to 200 policy changes at once. Changes that are already acknowledged are counted, not duplicated. Returns 400 when none of the IDs exist. Requires a plan with the compliance dashboard and an API key with `write` scope.

**Parameters**

* `diff_ids` (body, required): Policy diff IDs to acknowledge; IDs that do not exist are counted in `invalid_ids`
* `notes` (body)

**Example request**

```bash
curl -X POST "https://backworkhealth.com/api/v1/compliance/ack/bulk" \
  -H "Authorization: Bearer $BACKWORK_API_KEY" \
  -H "Content-Type: application/json" \
