Notification Hub: WebHook Examples

Part of Notification Hub.

Telegram

Send messages to a Telegram chat via Bot API.

Prerequisites:

1. Open Telegram and search for @BotFather
2. Send /newbot and follow the instructions to get your bot token
3. Send any message to your bot, then open in a browser:

   https://api.telegram.org/bot<TOKEN>/getUpdates

4. Find "chat":{"id": 123456789}: that number is your chat_id

Configuration:

Field	Value
URL	https://api.telegram.org/bot<YOUR_BOT_TOKEN>/sendMessage
Method	Post
Body Type	Json
Auth: Type	None

Body:

{
  "chat_id": "YOUR_CHAT_ID",
  "text": "%subject%\n\n%body%"
}

The message is sent as plain text. Do not add parse_mode: "HTML": the placeholders are not escaped for HTML, so a < or & in a notification would be read as markup.

Microsoft Teams

Send messages to a Teams channel via Incoming Webhook.

Prerequisites:

1. In Teams open the channel → … → Connectors
2. Add Incoming Webhook, set a name and copy the generated URL

Microsoft is migrating Teams connectors to Power Automate workflows. If the classic connector is unavailable, create a workflow in Teams with an HTTP trigger and use that URL instead.

Configuration:

Field	Value
URL	https://outlook.office.com/webhook/<YOUR_WEBHOOK_URL>
Method	Post
Body Type	Json
Auth: Type	None
