# Sending Notifications

Apps and NFT collections that want to use our notification protocol to interact with their users will receive access to a notification dashboard from which they can send notifications. They will be able to see the number of subscribed keys, their casts, and other general statistics.

**Panel URL**: <https://panel.aptcast.live>

Apart from the dashboard, we provide **API** endpoints that let apps integrate notifications in their own custom business flows.&#x20;

#### **There are two types of notifications that can be sent, broadcast and unicast**

{% endhint %}

1. **Broadcast** notifications are sent to all keys that are subscribed to the dApp.&#x20;
2. **Unicast** notifications are sent to a single targeted key that is subscribed to the dApp.

Broadcast notifications **are not** sent right away, they are subjected to review before being sent out to users.

> Even unicast notifications will be subject to review while we are in the first few days of beta.
