# Wallets

Notifications on wallet addresses are `address_activity` event type. Common use cases are to provide user payment confirmations, hosted wallet updates or track other smart money wallets.  

**Event Type:** `address_activity`

To create an address activity event, send a `POST` request to the `/api/v1/nodefy/notifications/` endpoint with the following JSON payload:

#### Example Request:

```json
{
    "external_user_id": "test123",                          //optional
    "channel": "EMAIL",                                     //required
    "notification_name": "Payroll Complete",                //optional
    "template": "Your monthly payroll has been completed"   //optional 
    "delivery_location": "hr@company.xyz",                  //required
    "event_details": {
        "network": "BASE_MAINNET",                          //required 
        "event_type": "ADDRESS_ACTIVITY",                   //required
        "addresses": ["0x60e4d8...a7c6"],                   //required
}
```

#### Required `address_activity` parameter:

* **`addresses`:** An array of wallet address(s) to track. This address(s) should be a high-level identifier for the events you're interested in listening for. 

#### Wallet Filters

You can easily layer more nuanced filters like `to_address`, `from_address`, `token_type` and more using our filter system. See [Using Filters ](https://docs.nodefy.xyz/our-api-guide/using-filters)section for more details.
