TL;DR

Meta's paid, verified API for doing customer messaging on WhatsApp — far heavier to adopt than a Telegram bot.

Key Points

✓

Distinct from the free WhatsApp Business app: the API is for integrations, not for tapping out replies by hand [1].

✓

Requires a Meta Business account, a verified business, and a dedicated phone number [1][2].

✓

Business-initiated messages outside the customer service window must use pre-approved message templates [1].

✓

Pricing is per conversation rather than per message, so cost scales with volume [1].

✓

Reach is the reason to use it — WhatsApp is the dominant messaging app across much of Europe, Latin America, and Asia [2].

✓

Compared with a [[telegram-bot]], setup is slower and paid, which is why smaller teams often start on Telegram.

API versus the Business app

Two different products share the WhatsApp Business name and they are routinely confused. The WhatsApp Business app is a free mobile app for a single small business: you install it, you answer messages by hand, and it adds a catalog and away messages. The WhatsApp Business Platform is an API for software — it has no interface of its own, and you either build against it or buy a tool that has ^[1]^[2]. Only the second supports a real Omnichannel Support setup where conversations flow into a Shared Inbox or Ticketing System alongside other channels. Choosing between them is mostly a question of whether a human will always be the one typing.

Templates, windows, and cost

WhatsApp restricts business-initiated contact far more tightly than most channels. When a customer messages you, a customer service window opens during which you can reply freely. Outside that window you may only send a pre-approved template — a message whose wording Meta has reviewed in advance — and templates are categorised by purpose, with marketing templates priced differently from utility ones ^[1]. Billing is per conversation rather than per message, so a long back-and-forth costs the same as a short one. This structure exists to keep WhatsApp from becoming a marketing channel users abandon, and it shapes design: a Proactive Chat strategy that works on a website does not transfer directly to WhatsApp.

How it compares with Telegram

The honest comparison is reach against friction. WhatsApp has the larger audience in most of the world, so if your customers already use it, meeting them there removes a real barrier ^[2]. But adoption is heavy: business verification, a dedicated number, template approval, per-conversation pricing, and usually a paid provider in between. A Telegram Bot is the opposite — free, created in minutes through BotFather, with no verification and no template regime — which is why it suits founders and small teams testing whether chat support is worth doing at all. Many businesses end up on both, using Telegram for the internal operator surface described in Telegram Integration and WhatsApp as an additional customer-facing channel.

Telegram Bot

A Telegram bot is an automated account inside Telegram, run by software rather than a person, that can send and receive messages through the Telegram Bot API. Businesses use bots to deliver website chat messages, notifications, and support conversations into Telegram, where they can be answered from a phone.

Business Messaging

Business messaging is the practice of companies communicating with customers through conversational messaging channels (website chat, in-app threads, SMS, and apps like WhatsApp or Messenger) instead of phone calls, email, or formal request forms. The interaction is treated as a persistent, two-way conversation rather than a one-off session, so context and history carry forward over time.

Omnichannel Support

Omnichannel support is a customer service strategy that connects every channel a customer might use - live chat, email, phone, SMS, social, and messaging - into one continuous, context-aware experience. Unlike multichannel support, where each channel runs in its own silo, omnichannel keeps conversation history and customer context flowing across channels so people never have to repeat themselves.

Asynchronous Messaging

Asynchronous messaging is a style of customer conversation that can start, pause, and resume at the participants' convenience, kept in a single continuous thread rather than a real-time session that ends when either party leaves. Customers send a message and pick up the reply later, without staying glued to the chat window.

Telegram Customer Support

Telegram customer support is the practice of handling customer questions through Telegram instead of a traditional help desk — either by talking to customers in Telegram directly, or by routing website chat into Telegram so the business can reply from the app it already uses.

Conversational Commerce

Conversational commerce is the practice of buying, selling, and supporting customers through real-time conversation in messaging channels, live chat, and voice or AI assistants, so shoppers can ask questions and complete purchases inside a chat thread. It sits at the intersection of e-commerce and messaging, turning a back-and-forth dialogue into a path to purchase.
