# Aircraft filtering

By default, flight webhooks deliver events for all tracked aircraft. To receive notifications for specific aircraft only, register their tail numbers:

### Register Aircraft

```bash
curl -X POST "https://api.aviowiki.com/webhooks/WSAxxxxxxxx/flight/aircraft?registration=DABCD&registration=GABXY" \
  -H "Authorization: Bearer YOUR_API_TOKEN"
```

{% hint style="info" %}
Once you register at least one aircraft, you will only receive flight events for registered aircraft.
{% endhint %}

### Remove Aircraft

```bash
curl -X DELETE "https://api.aviowiki.com/webhooks/WSAxxxxxxxx/flight/aircraft?registration=DABCD" \
  -H "Authorization: Bearer YOUR_API_TOKEN"
```

### Remove All Aircraft

```bash
curl -X DELETE "https://api.aviowiki.com/webhooks/WSAxxxxxxxx/flight/aircraft/all" \
  -H "Authorization: Bearer YOUR_API_TOKEN"
```

Removing all registered aircraft returns the subscription to receiving all flight events.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.aviowiki.com/webhooks/aircraft-filtering.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
