Telegram Bot Overview

With the Telegram Bot API, you can build bots that perform a variety of tasks,
including:

  • Sending and receiving messages
  • Social networking
  • Content management
  • File sharing
  • Location sharing
  • Bot administration
  • And more!

Trigger Code

import base from "../common/webhooks.mjs";

export default {
  ...base,
  key: "telegram_bot_api-channel-updates",
  name: "New Channel Updates (Instant)",
  description: "Emit new event each time a channel post is created or updated.",
  version: "0.1.3",
  type: "source",
  dedupe: "unique",
  methods: {
    ...base.methods,
    getEventTypes() {
      return [
        "channel_post",
        "edited_channel_post",
      ];
    },
    getMeta(event, channelPost) {
      return {
        id: event.update_id,
        summary: `${channelPost.chat.title} - ${channelPost.text}`,
        ts: new Date(channelPost.edit_date ?? channelPost.date),
      };
    },
    processEvent(event) {
      const channelPost = event.edited_channel_post ?? event.channel_post;

      if (!channelPost?.chat) {
        throw new Error(`Expected event to contain a chat, but received: ${JSON.stringify(event)}`);
      }

      this.$emit(event, this.getMeta(event, channelPost));
    },
  },
};

Trigger Configuration

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.
LabelPropTypeDescription
Telegram BottelegramBotApiappThis component uses the Telegram Bot app.
N/Adb$.service.dbThis component uses $.service.db to maintain state between executions.
N/Ahttp$.interface.httpThis component uses $.interface.http to generate a unique URL when the component is first instantiated. Each request to the URL will trigger the run() method of the component.

Trigger Authentication

Telegram Bot uses API keys for authentication. When you connect your Telegram Bot account, Pipedream securely stores the keys so you can easily authenticate to Telegram Bot APIs in both code and no-code steps.

To use the Telegram Bot API, you must first create a new bot by chatting with the BotFather.
