Telegram Bot Overview#

The Telegram Bot API allows you to build bots that can interact with users on the Telegram platform. Using Pipedream, you can automate messaging, handle commands, and trigger actions based on conversations or alerts. Pipedream's serverless execution model enables you to create complex workflows involving Telegram messages without managing any infrastructure. With Pipedream's integration, you can process inbound messages, send outbound notifications, and connect the Telegram Bot API with numerous other services to create powerful automation solutions.

Trigger Code#

import base from "../common/webhooks.mjs";
import sampleEmit from "./test-event.mjs";

export default {
  ...base,
  key: "telegram_bot_api-message-updates",
  name: "New Message Updates (Instant)",
  description: "Emit new event each time a Telegram message is created or updated.",
  version: "0.1.5",
  type: "source",
  dedupe: "unique",
  methods: {
    ...base.methods,
    getMeta(event, message) {
      return {
        id: event.update_id,
        summary: message.text,
        ts: new Date(message.edit_date ?? message.date),
      };
    },
    getEventTypes() {
      return [
        "message",
        "edited_message",
      ];
    },
    processEvent(event) {
      const message = event.edited_message ?? event.message;
      this.$emit(event, this.getMeta(event, message));
    },
  },
  sampleEmit,
};

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.

Label	Prop	Type	Description
Telegram Bot	`telegramBotApi`	`app`	This component uses the Telegram Bot app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
N/A	`http`	`$.interface.http`	This component uses `$.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.

After you create your bot, copy the bot token and add it below.

Browserless Overview#

The Browserless API on Pipedream allows you to automate browser actions without the overhead of managing your own browser infrastructure. This service provides a way to run Chrome browser sessions programmatically, making it ideal for web scraping, automated testing, and screenshot capture. Leveraging this on Pipedream, you can create serverless workflows that interact with web pages, extract data, and perform actions as a human would, all in a scalable and efficient manner.
