# Send Notifications

> How to send notifications with Sendify (because what’s the point of a notification system if you don’t send any?).

## Sending Notifications (Because That’s the Whole Point, Right?)

Oh, so you actually want to **send** notifications? Wow, what a revolutionary concept. Luckily for you, it’s so easy even a goldfish with Wi-Fi could do it. Let’s break it down.

## Before You Start: API Keys & Unique User IDs Matter!

First things first—do you have your **API keys** set up? No? Then what are you doing here? Notifications don’t send themselves. Check the [Installation Guide](/installation) before wasting any more of your precious time.

Next, let’s talk **user IDs**. And I cannot stress this enough—**they must be unique**. If you think using "user1" for every single person is a genius idea, congratulations, you just created the world's worst notification system. Use an email, a UUID, or literally anything that **distinguishes one user from another**. A random string? Sure, as long as it’s actually unique per user.

## Server (a.k.a. The Brains Behind It All)

```ts theme={null}
import { sendify } from "sendify";

// Imagine this is inside an API route where an auction is created

await sendify.sendNotifications(
  ["user123", "user456"], // Array of user IDs to notify (you know, unique ones)
  "A new auction just went live!", // Notification content (make it interesting, maybe?)
  "Check it out", // Button text (optional, but who doesn’t like buttons?)
  "https://yourapp.com/auctions/123" // Button URL (optional, unless you want users to guess where to go)
);
```

## Client (a.k.a. Where Users See The Magic)

<CodeGroup>
  ```tsx TSX theme={null}
  import { NotificationFeed } from "sendify";

  const UserNotifications = ({ userId }: { userId: string }) => {
    return (
      <div>
        <NotificationFeed userId={userId} />
      </div>
    );
  };

  export default UserNotifications;
  ```

  ```jsx JSX theme={null}
  import { NotificationFeed } from "sendify";

  const UserNotifications = ({ userId }) => {
    return (
      <div>
        <NotificationFeed userId={userId} />
      </div>
    );
  };

  export default UserNotifications;
  ```
</CodeGroup>

## Breakdown of `sendify.sendNotifications()` (Because Details Matter, Apparently)

1. **First argument (`userIds`)** – Who’s getting the notification? This must be an array. One user? `["user123"]`. Multiple users? `["user1", "user2"]`. **Make sure these are unique! I will not repeat this again. Maybe on the next page. Who knows?**
2. **Second argument (`content`)** – The actual message. Keep it short and sweet. Nobody wants to read a novel in their notifications.
3. **Third argument (`buttonText` - optional)** – If you want a button, this is the text. If not, then just pretend this argument doesn’t exist.
4. **Fourth argument (`buttonUrl` - optional)** – Where does the button take users? Your app? A cat video? It’s up to you.

## That’s It.

You now know how to send notifications like a pro. No unnecessary bloat, no overcomplicated nonsense—just clean, real-time notifications. Now go forth and notify the world. 🚀 (Or don’t. I’m not your boss.)
