#### Example

cURL

{% code overflow="wrap" %}

```sh
curl -X POST 'https://api.eu.navixy.com/v2/user/session/push_token/bind' \
    -H 'Content-Type: application/json' \
    -d '{"hash": "22eac1c27af4be7b9d04da2ce1af111b", "application": "navixy_android_viewer", "token": "f4be7b9d04da2ce1af111b"}'
```

{% endcode %}

#### Response

```json
{
  "success": true
}
```

Using `category_filter` you can filter out unwanted notifications categories.

If `category_filter` equals to `*` this means all categories allowed.

Delimited with comma list means that allowed only listed categories i.e. `chat_message,history_rule`.

Prepended with minus and delimited with comma list means that all categories allowed except given i.e. – `history_task,history_rule`.

**Possible categories:**

* `chat_message` – notification about new chat message.
* `history_rule` – notifications related to rule actuation.
* `history_task` – notifications related to tasks.
* `history_info` – service information.
* `history_service_task` – service task notifications.
* `history_work_status` – work status notifications.
