title: "Dismiss Merge Suggestion"
description: "Drops a suggestion that an Incident Management incident is the same as an open incident from another source."

`POST /api/im/incidents/:id/dismiss-merge-suggestion`

When an incident is created, Incident Management looks for open incidents from other alert sources of your organization that are probably the same (same service or same host, triggered within 15 minutes) and lists them in `mergeSuggestions` of [Get Incident](/api/incident-management/get-incident). Nothing is merged automatically. This endpoint drops one suggestion when it is wrong; to accept it, use [Merge Incidents](/api/incident-management/merge-incidents) instead.

The dismissal is written to the incident timeline (`merge_suggestion_dismissed`, payload `{ targetIncidentId }`) and to the organization audit log. Neither incident is changed otherwise, nobody is notified.

## Authentication

Any IM-eligible role or an organization-wide API token, see [Authentication](/api/incident-management#authentication). Same rights as merging: you must be a member of the team of incident `:id` or an organization `admin`.

## Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `targetIncidentId` | integer | Yes | The `incidentId` of the suggestion in `mergeSuggestions`. |

```bash
curl -X POST "$BASE_URL/api/im/incidents/43/dismiss-merge-suggestion" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "targetIncidentId": 41 }'
```

## Response

`200 OK`:

```json
{ "ok": true }
```

## Common errors

- `401 Unauthorized` when not authenticated
- `403 Forbidden` (`imTeamMembershipRequired`) when you are not a member of the incident's team and not an organization `admin`
- `400 Bad Request` (`invalidRequestBody`) when `targetIncidentId` is missing, not a positive integer, or the body has other fields
- `404 Not Found` (`imIncidentNotFound`) when the incident does not exist or belongs to another organization
- `404 Not Found` (`imMergeSuggestionNotFound`) when the incident has no open suggestion for `targetIncidentId` (never suggested, or already dismissed)
