Is a simple Notification system based on express.js and a telegram bot. When a webhook is called, the bot sends a notification to chat members.
Create a .env file with your data (see env.dist for an example)
Run npm run start
Subscribe to the telegram bot as usual an you'll get an API_KEY. Send notification like this way:
curl --request GET 'https://MY-ENDPOINT.COM/send-notification?message=simple_message_please' \ --header 'x-api-key: API_KEY'
