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-new-updates",
  name: "New Updates (Instant)",

    getMeta(event) {
      const {
        update_id: id,
        ...eventDetails
      } = event;
      const eventType = Object.keys(eventDetails).pop();
      const summary = `New ${eventType} update: ${id}`;
      const ts = eventDetails[eventType].edit_date ?? eventDetails[eventType].date;

      return {

    },
    processEvent(event) {
      this.$emit(event, this.getMeta(event));
    },
  },
  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.
Update Types	`updateTypes`	`string[]`	Select a value from the drop down menu:`{ "label": "Message", "value": "message" }{ "label": "Edited Message", "value": "edited_message" }{ "label": "Channel Post", "value": "channel_post" }{ "label": "Edited Channel Post", "value": "edited_channel_post" }{ "label": "Inline Query", "value": "inline_query" }{ "label": "Chosen Inline Result", "value": "chosen_inline_result" }{ "label": "Callback Query", "value": "callback_query" }{ "label": "Shipping Query", "value": "shipping_query" }{ "label": "Pre Checkout Query", "value": "pre_checkout_query" }{ "label": "Poll", "value": "poll" }{ "label": "Poll Answer", "value": "poll_answer" }{ "label": "My Chat Member", "value": "my_chat_member" }{ "label": "Chat Member", "value": "chat_member" }{ "label": "Chat Join Request", "value": "chat_join_request" }`

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.

Helper Functions Overview#

The Helper Functions app on Pipedream is a set of pre-built functions that streamline common tasks in your workflows. It acts like a Swiss Army knife for developers, providing essential tools such as format conversion, date manipulation, and text processing. By leveraging these functions, you can reduce the boilerplate code needed for routine operations, speeding up the development of intricate automations. The Helper Functions API can be a game changer when it comes to tasks like parsing dates in user-friendly formats, encoding and decoding data, or generating UUIDs, making them more efficient and less error-prone.
