# NegativeKeyword.MatchType

The matching behavior used to compare this negative keyword against user search queries.

```
string NegativeKeyword.MatchType
```

## Discussion

Unlike positive keywords, negative keywords can use `EXACT`, `BROAD`, or `PHRASE`, but not `CATEGORY` matching.

### Example

```json
{
  "matchType": "BROAD"
}
```

See [`KeywordMatchType`](/documentation/Apple-Ads-Platform-API/KeywordMatchType) for additional context.
