Get Notified on Telegram When Your EAS Build Completes! 💬

Stop refreshing the Expo dashboard waiting for builds. In this setup, EAS pings a webhook when your build finishes, an Expo Router API route catches it, and a Telegram bot messages you with the status, commit, and a link to install the artifact. I build the whole thing in the video, including signature validation so nobody can spoof your webhook.

The same pattern works for Slack, email, or anything else you want to notify.

What's inside

• Creating a Telegram bot with BotFather and grabbing the group chat ID
• An Expo Router API route that turns webhook payloads into messages
• Registering the webhook with eas webhook:create
• Verifying the expo-signature header so spoofed requests get rejected
• Deploying the API with eas deploy --prod
• Testing end to end with a real iOS production build
