How to Integrate Telegram with Bubble

What a Telegram Integration Does for Your Bubble App

Telegram's Bot API is one of the most developer-friendly messaging APIs available. Unlike WhatsApp's Business API with its approval processes and template requirements, Telegram lets you create a bot in minutes and start sending messages immediately with no review process and no per-message fees. For Bubble builders, this makes Telegram the fastest messaging integration you can ship.

A Telegram bot connected to your Bubble app can send notifications and alerts to users, receive and process user messages, respond to commands with data from your Bubble database, send rich media (photos, documents, audio, video), display inline keyboards for interactive workflows, and manage group conversations. The bot acts as a bridge between your Bubble app and Telegram's 800+ million users.

Use Cases for Telegram Bots in Bubble

The first use case is operational alerts. Your Bubble app monitors critical events — new sign-ups, failed payments, server errors, support tickets, large orders — and sends instant notifications to a Telegram group or channel where your team operates. This is faster and less noisy than email alerts. Many startup teams use a Telegram channel as their real-time operational dashboard.

The second use case is user-facing notifications. Users connect their Telegram account to your Bubble app and receive notifications through Telegram instead of (or in addition to) email. Appointment reminders, task assignments, status updates, and delivery notifications all arrive in the same messaging app users already check constantly. Telegram's unlimited free messaging makes this cost-effective at any scale.

The third use case is interactive bots. Your Telegram bot responds to user commands with data from your Bubble database. A user types /status and gets their current project status. They type /invoice and get their latest invoice. They tap an inline keyboard button to approve a request, and your Bubble app processes the approval. This creates a lightweight mobile interface to your Bubble app without building a native mobile app.

Creating a Telegram Bot

Creating a Telegram bot takes about two minutes. Open Telegram, search for @BotFather, and start a conversation. Send /newbot, choose a display name and username (must end in "bot"), and BotFather responds with your bot's API token. That token is your entire authentication credential — keep it secret. Anyone with the token can control your bot.

Store the token in Bubble's API Connector as a private value. Never expose it in front-end elements, URL parameters, or client-side JavaScript. The token doesn't expire unless you explicitly revoke it through BotFather.

Setting Up the API Connector for Telegram

In Bubble's API Connector, create an API called "Telegram" with base URL https://api.telegram.org/bot{YOUR_BOT_TOKEN}. Note the "bot" prefix before the token in the URL — this is required by Telegram's API format.

Create the following API calls. First, a POST to /sendMessage with JSON body parameters for chat_id (the recipient's Telegram user ID or group chat ID), text (the message content), and optional parse_mode ("HTML" or "MarkdownV2" for formatted messages). Second, a POST to /sendPhoto for sending images, with chat_id, photo (URL or file ID), and optional caption. Third, a POST to /sendDocument for sending files.

To send a message, your Bubble workflow calls the sendMessage endpoint with the recipient's chat_id and the message text. The chat_id is the unique identifier for a Telegram user or group. You get this ID when a user starts a conversation with your bot (from the incoming webhook) and store it in your Bubble database linked to the user record.

Telegram supports HTML formatting in messages (bold, italic, links, code blocks) when you set parse_mode to "HTML." This lets you send rich, well-formatted notifications from Bubble. For example, an order notification might include bold text for the order number, a link to view it in your Bubble app, and a formatted table of line items.

Receiving Messages via Webhooks

When a user sends a message to your bot, Telegram can deliver it to your Bubble app via webhook. Set up a Backend Workflow API endpoint in Bubble to receive incoming messages. Then register this URL with Telegram by calling the /setWebhook endpoint with your Bubble webhook URL as the url parameter.

Call the setWebhook endpoint once (you can do it from the API Connector's "Initialize" button or from a separate one-time workflow). Telegram starts sending all incoming messages to your Bubble endpoint immediately. The webhook payload includes the sender's user ID, username, first and last name, the message text, any media attachments, and a timestamp.

In your Bubble backend workflow, parse the incoming message and decide how to respond. For command-based bots, check if the message text starts with a slash command (/start, /help, /status). For conversational bots, analyze the message content and generate an appropriate response. Then call the sendMessage endpoint to reply.

A typical command handler workflow looks like this: receive the webhook, extract the message text and chat_id, check if the text matches a known command, query your Bubble database for the relevant data, format the response, and send it back through the sendMessage API call. The user sees the response in their Telegram chat within seconds.

Inline Keyboards for Interactive Workflows

Telegram's inline keyboards turn messages into interactive interfaces. You can attach buttons to any message that trigger callback actions in your Bubble app. When a user taps a button, Telegram sends a callback_query webhook with the button's data payload to your Bubble backend.

To send a message with an inline keyboard, include a reply_markup parameter in your sendMessage call. The markup is a JSON object containing an inline_keyboard array — an array of button rows, where each button has text (the label) and callback_data (a string your app receives when the button is tapped).

For example, an approval workflow: your Bubble app sends a message to a manager saying "New expense request: $500 from John Smith for client dinner" with two inline keyboard buttons: "Approve" (callback_data: "approve_123") and "Reject" (callback_data: "reject_123"). When the manager taps "Approve," your Bubble backend receives the callback, parses the expense ID from the callback_data, updates the expense record in your database, and sends a confirmation message to both the manager and the requester.

This pattern works for any binary or multiple-choice decision: approving requests, assigning tasks, triaging support tickets, confirming deliveries, or voting in polls. It turns Telegram into a lightweight task management interface powered by your Bubble backend.

Common Pitfalls

The most common mistake is not handling the /start command. When a user first finds your bot and taps "Start," Telegram sends a message with the text "/start." If your bot doesn't respond, the user thinks it's broken. Always handle /start with a welcome message that explains what the bot does and lists available commands.

Bot token security is critical and often overlooked. If your bot token leaks (exposed in client-side code, committed to a public repo, shared in a screenshot), anyone can send messages as your bot, read incoming messages, and potentially access your users' data. Rotate the token immediately if you suspect it's compromised — use BotFather's /revoke command to get a new one.

Webhook reliability is another concern. If your Bubble backend workflow fails to return a 200 response quickly enough, Telegram retries the webhook delivery, which can cause duplicate message processing. Add deduplication logic to your webhook handler — check the message ID against previously processed messages before creating new records or triggering workflows.

Group chat behavior differs from private chats. In groups, your bot only receives messages that are specifically addressed to it (using @botusername or as a reply to the bot's message) unless you disable privacy mode through BotFather. If you're building a bot for group use, enable the appropriate privacy setting and handle the different message formats groups produce.

Rate limits are generous but exist. Telegram allows about 30 messages per second to different chats and one message per second to the same chat. If you're sending bulk notifications to many users, use Bubble's "Schedule API Workflow on a List" with slight delays between messages to stay within limits.

DIY vs Hiring a Bubble Developer

Telegram bot integration is one of the easier API integrations for Bubble. Creating the bot, setting up the API Connector, and sending your first message takes a few hours. Receiving messages via webhook and responding to commands takes another half day. Building interactive workflows with inline keyboards takes one to two days. A full-featured Telegram bot integration, including command handling, inline keyboards, media support, and user linking, can be completed in three to five days by a solo builder.

Where external help makes sense is if you're building a complex conversational bot with multiple workflow branches, state management (remembering where the user is in a multi-step process), and integration with multiple Bubble data types. At that point, you're building a mini-application inside Telegram, and architectural decisions matter more than API configuration.
