Firebase cloud functions as Webhooks

Broadcast Travis CI results to a Telegram Channel

First, get your own Telegram Bot token.

Create file functions/src/local.ts, with content:

export const BOT = {
  token: '<telegram-bot-token>',
  apiPrefix: 'https://api.telegram.org/bot<telegram-bot-token>',
  chatId: '<telegram-chat-id>',
};

The chatId can be a Telegram Channel or a Group, you can find it easily through Telegram Web.

• Channel: find this in the browser address bar: im?p=c<channel-id>_xxx, chatId for this channel will be -100<channel-id>
• Likewise, for Group im?p=g<group-id>, the chatId will be -<group-id>

Finally, don't forget to add your bot to the Channel or Group!
