WhatsApp or Telegram for your AI agent?

Both WhatsApp and Telegram work well as a front door for your AI agent. Your customers send a message, the agent replies. The experience from their side is nearly identical.

The difference is in what happens behind the scenes: how much setup is involved, what rules you need to follow, and what trade-offs come with each platform. This guide walks through both options so you can choose the one that fits your business.

The summary

Both channels work. Both connect to your agent in the same way. The choice comes down to where your customers already are, how much setup you want to take on, and whether platform-specific rules matter for your use case.

WhatsApp is the stronger choice when your customers are already there. Millions of Australian businesses use it daily, and for many industries it is the expected channel. The official route takes roughly a week to set up, involves Meta verification, and comes with a few messaging rules. Once it is running, it is stable, professional, and familiar to your audience.

Telegram is the simpler path. No verification, no approval process, no per-message fees, and no 24-hour reply windows. It is a strong default when you do not have an existing customer base on WhatsApp, or when you want to get an agent live quickly and iterate from there.

There is also an unofficial way to connect WhatsApp, covered later in this guide. It is fast to set up but carries real risk, and we only recommend it for internal team use.

WhatsApp

Two ways to connect WhatsApp to your agent. Which one fits depends on whether your customers or only your internal team will use it.

Official route (for your customers)

This is Meta's sanctioned path: the WhatsApp Business Platform (Cloud API). It gives you a verified business profile, a stable connection, and no account-ban risk. It is the only WhatsApp route we recommend when your customers will be messaging the agent.

Why businesses choose this route

• Your customers are already on WhatsApp. They know your number, they message you there, and switching them to another app would create friction.
• Professional trust. A verified WhatsApp business profile carries weight. Some industries (real estate, trades, logistics) expect it.
• Consolidation. If your team already manages customer conversations on WhatsApp, adding an agent to the same channel keeps everything in one place.

What you provide

These are Meta's requirements, not ours. We do not need any of this to run your agent, but Meta will not grant API access without it.

• A Meta Business account. If you have a Facebook business page, you already have one. Otherwise it takes about 10 minutes at business.facebook.com.
• A dedicated phone number for the agent. Not your existing WhatsApp number. A $10 to $15 per month prepaid SIM works well. Once registered to the API, the number leaves the regular WhatsApp app. This is a one-way decision.
• Verification documents. ABN plus one business document (ASIC extract or a utility bill). Meta uses these to confirm you are a real business.
• Business profile content. Display name, logo, description, website, address. This is what your customers see inside WhatsApp.

What we handle

Connecting the verified account to your agent, wiring in your business profile, submitting message templates for approval (if you need proactive outreach), and end-to-end testing before go-live.

The messaging rules

• Reactive messaging is free and unrestricted. When a customer writes to your agent, it can reply freely for 24 hours with any content. Every reply resets the timer. For back-and-forth conversations (your team talking to the agent, or a customer in an active thread), this window effectively never expires.
• Proactive messaging needs pre-approved templates. If your agent wants to start a conversation with someone who has not written to you recently (reminders, promotions, re-engagement), it needs to use a Meta-approved template. These cost a few cents per send.

Most agents we set up sit comfortably on the reactive side and rarely need templates. The real investment in WhatsApp (official) is the setup itself.

Unofficial route (a shortcut with trade-offs)

There is a second way to connect WhatsApp to your agent: linking a regular WhatsApp account by QR code, the same way WhatsApp Web works. Under an hour, no Meta verification, no ABN, no templates, no per-message fees. OpenClaw supports it and we will set it up if you ask.

How it works

• You sign a WhatsApp account into a phone (a dedicated number, not your personal one).
• We start the setup and show a QR code.
• You scan it from that WhatsApp (Settings → Linked Devices → Link a device), the same way you would link WhatsApp Web.
• Your agent sends and receives messages through that account. After scanning, the phone does not need to stay online.

What you provide

• A dedicated phone number with a WhatsApp account. Never your personal WhatsApp. If Meta bans the account, the number goes with it. Use a number you could afford to lose.
• A phone to do the initial QR scan. Any phone where the WhatsApp account is signed in. After the scan it can sit in a drawer.
• Willingness to re-scan occasionally. The linked device can be logged out by Meta from time to time. If it happens, we send a new QR and you scan it again.

The real risk

Unofficial linking breaches WhatsApp's terms of service for commercial use. Meta is known to ban accounts connected this way, sometimes after weeks, sometimes after months, without notice. If that happens mid-conversation, the conversation and the number are gone.

For internal team use, a ban is inconvenient but manageable. We rescue the agent and re-link. For your paying customers, it can be more damaging: active conversations disappear and the number they saved stops working. We will set this up for customer-facing use if you ask, but we recommend keeping it internal.

Telegram

Telegram connects to your agent through an official Bot API. No verification, no approval process, no per-message fees, and no 24-hour reply windows. The agent is live within the hour.

Why businesses choose Telegram

• Speed. You can go from zero to a working agent in under an hour. No forms, no waiting for Meta to verify your business.
• No messaging restrictions. Your agent can message anyone, anytime, with any content. No templates, no reply windows.
• No dedicated phone number required. The agent runs through a Telegram bot token, not a phone number.
• Good for testing. If you want to try an AI agent with real users before committing to a specific channel, Telegram gives you the lowest-friction starting point.
• Groups and channels. Telegram makes it straightforward to add your agent to group chats, which is useful for team-based workflows and internal ops.

Considerations

Telegram is a strong platform, but it is worth being aware of a few things.

• Audience familiarity. Not everyone has Telegram installed. In Australia, WhatsApp is more widely used for business messaging. If your customers are not already on Telegram, they will need to download it. For many, this is a small ask. For others, particularly older demographics or those in industries where WhatsApp is standard, it can be a barrier.
• Perception. Telegram has a reputation in some circles for cryptocurrency spam and unmoderated groups. This does not affect your agent or your conversations in any way, but some customers may have a bias against the platform based on past experience. Worth knowing, even if it is not a technical concern.
• Professional signalling. For certain industries (property, trades, professional services), being reachable on WhatsApp can signal professionalism simply because it is the expected channel. Telegram works identically from a technical standpoint, but the optics differ depending on your audience.

Common questions

Can I switch channels later?

Yes. Your agent is built in OpenClaw, which is independent of the messaging channel. If you start on Telegram and later want to add WhatsApp (or the other way around), we connect the new channel without rebuilding anything. You can also run both at the same time.

Can I use both channels at once?

Yes. Some businesses run Telegram for internal team use and WhatsApp for customer-facing conversations. The same agent handles both.

What about other channels?

OpenClaw also supports email, SMS, Slack, Discord, and web chat. This guide focuses on WhatsApp and Telegram because they are the two most common messaging channels our customers ask about.

What if my customers do not want to download Telegram?

That is a perfectly valid concern and often the deciding factor. If your audience is already on WhatsApp and unlikely to move, the official WhatsApp route is the right call. The setup takes a bit longer, but it meets your customers where they are.

Is one channel more secure than the other?

Both WhatsApp and Telegram encrypt messages in transit. WhatsApp uses end-to-end encryption by default. Telegram encrypts client-to-server and offers optional end-to-end encryption through "Secret Chats," though bot conversations use standard encryption. For most business use cases, both are more than adequate.

Our recommendation

Start with the channel that makes the most sense for your audience.

If your customers are on WhatsApp and expect to reach you there, go with WhatsApp (official). The setup takes a week, but once it is running, it is the most natural experience for your audience.

If you do not have an existing customer base on WhatsApp, or you want the fastest path to a working agent, Telegram is the simpler starting point. You can always add WhatsApp later.

Either way, we handle the setup. You get a working agent.
