# How to test a notification channel

Before relying on a delivery channel, run a test to confirm it works.

## When it is useful

- You set up a new channel (Telegram, Viber, browser).
- You want to verify delivery before use.
- You see errors when notifications are sent.

## What to know

- A **test notification** is sent **only** through the selected channel (not all channels).
- **Tests do not change** your notification settings.
- **Linked channels** — for Telegram/Viber you must finish linking before testing.

## Before you start

- The channel is configured (for Email/Telegram/Viber — by an administrator).
- The channel is connected (for Telegram/Viber — linked to your profile).
- You are logged in.

## Steps

### 1. Open notification settings

Go to **Profile** → **Notifications** → **Channels** tab.

### 2. Find the channel

Scroll to the channel:

- Bell notifications
- Banner notifications
- Email
- Telegram
- Viber
- Browser notifications

### 3. Click Test

Click **Test** next to the channel.

### 4. Check the outcome

Depending on the channel:

- **Bell** — appears in the bell menu
- **Banner** — toast in the top-right corner
- **Email** — test arrives at your profile email
- **Telegram** — test arrives in Telegram
- **Viber** — test arrives in Viber
- **Browser** — a system browser notification appears

### 5. Read the result message

The app shows:

- **Success** — “Test notification sent via {channel}”
- **Error** — details (for example, “Channel not connected”)

## Result

After a successful test you can:

- Use the channel for notifications
- Be confident delivery works
- Catch issues early

## Troubleshooting

### Channel not connected

**Issue:** “Channel not connected” for Telegram/Viber.

**What to do:**
- Complete linking first — [How to link Telegram](/en/notifications/how-to/connect-telegram-channel.md) or [How to link Viber](/en/notifications/how-to/connect-viber-channel.md).
- Test again after linking.

### Channel not configured

### Test notification did not arrive

**What to do:**
- Confirm the channel is connected and configured.
- For browser notifications, check browser settings.
- For Telegram/Viber, check the app.
- Try **Test** again.
- Optionally open the browser developer tools (F12 → Console) for errors.

### Send failed

**Issue:** “Could not send test notification”.

**What to do:**
- Confirm you are logged in.
- Confirm the channel is configured and connected.
- Refresh the page and try again.
- Ask your administrator to verify configuration.

## Important

- Only the selected channel is tested.
- A test does not change your settings.
- For Telegram/Viber, link the channel before testing.
