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
- 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
