How to Build a Telegram Lead Capture Bot in 60 Seconds

If you run a B2B SaaS, an agency, or a crypto project, your Telegram community is likely full of silent observers. They read your updates, they watch your announcements, but they don't convert. Why? Because the friction to go from Telegram to a landing page to a signup form is too high.

What if you could capture leads directly inside Telegram?

In this guide, we will show you exactly how to build a Telegram lead capture bot that qualifies prospects and automatically syncs their data to your CRM—all without writing a single line of code.

Why Use a Telegram Lead Capture Bot?

Traditional lead generation relies on driving traffic to a landing page. But on Telegram, you already have their attention. An AI lead capture bot acts as a 24/7 Sales Development Representative (SDR) that lives directly in your users' DMs.

Step 1: Get Your Telegram Bot Token

The first step is to create the "shell" of your bot on Telegram.

2Send the command /newbot.

3Follow the prompts to give your bot a name and a username (which must end in "bot").

4Copy the API Token provided by BotFather.

Step 2: Give Your Bot an "AI Brain"

A standard Telegram bot is dumb. To make it a smart lead capture tool, you need to connect it to an AI model like GPT-4o or Claude 3.5.

Instead of building a custom backend, you can use EasyAIWrapper to handle the AI orchestration.

1Log into your EasyAIWrapper dashboard.

2Click "Deploy New Bot" and select Telegram.

3Paste the API Token you got from BotFather.

Step 3: Program the Lead Capture Prompt

The secret to a high-converting lead capture bot is the "System Prompt." This is the set of hidden instructions the AI follows.

Set your bot's system prompt to something like this:

"You are a friendly sales assistant for [Your Company]. Your goal is to qualify the user and collect their email address to book a demo. Ask what their primary use case is. Once they answer, ask for their email address. Be conversational and concise."

Step 4: Connect to HubSpot

Capturing an email in a chat log isn't enough. You need that data in your CRM.

With EasyAIWrapper's Growth plan, you can enable the native HubSpot integration. Every time the AI identifies an email address in the conversation, it automatically extracts it, summarizes the lead's qualifications, and creates a new Contact in HubSpot.
