# Making your first query

Now that you have obtained an `access_token` from the [Authentication](https://docs.butlr.io/getting-started/authentication) step, we are ready to make our first request. Here is an example of a request with authorization to our GraphQL API to obtain `sensors` data.

### Authorization in Header

```
{"Authorization": "Bearer [access_token]"}
```

### GraphQL Query

```graphql
query MyFirstQuery {
  sensors {
      data {
          client_id
          floor_id
          room_id
          hive_id
          hive_serial
          sensor_id
          name
          mac_address
          mode
          model
          sensitivity
          center
          height
          orientation
          field_of_view
      }
  }
}
```
