## Pair Your Device

## Create an API Key

[Create an API key in the web app](https://activitysmith.com/app/keys) and copy it.

## Send a Push Notification

Replace `your-api-key` below with your API key, then run the command:

```bash cURL
YOUR_API_KEY="your-api-key"

curl -X POST https://activitysmith.com/api/push-notification \
  -H "Authorization: Bearer $YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "New subscription 💸",
    "message": "Customer upgraded to Pro plan"
  }'
```

The notification will appear on your paired device.
