The way I would put it as someone who works at Beeper is: only use messaging automations for personal use, and don't use it to spam anyone or do anything you wouldn't do yourself within the app.
As long as you don't abuse and keep your usage within the parameters of any human, you'll be fine.
...until Meta decides they want to offer this kind of thing themselves and ban everyone else. Building your SaaS on top of someone else's SaaS is always a gamble, especially if said product is directly sold to users already and not a pure b2b intermediate.
I consider marketing use to be spam, and this is what the API is primarily meant for.
I understand that WhatsApp is kinda special in that it effectively replaced SMS in some parts of the world, but IMO this needs to be looked at through the lens of other Meta effort. The same is the case with Facebook/Messenger, and has been since before WhatsApp has been a (Meta) thing - they offer multiple different official ways to support spamming users and tricking them to buy stuff, but may the Lord have mercy on you should you want to create an auto-responder or "save to calendar" script and hook it up to your personal account.
Just yesterday I setup a bot which is easy via botfather
And also, setup an app (claude built it but I had to fiddle with it, it works like pagerduty) but uses cloudflate worker to push downtime/errors (via fcm) in production (from graphana) via webhooks to "full screen, by pass dnd, alerts, with loud music, this one: https://www.youtube.com/watch?v=H0IQBWWabuU )
I named the app "Siren".
It's not straightforward to have durable hard to miss alerts about your production enviornment but good thing is this doesn't cost a cent.
Telegram group alerts are from my teammates (small team 3 members) via bot.
And Siren is for only me as I am responsible for the backend with 10 microservices, centralized logging via graphana, alloy, loki, and for metrics Prometheus.
It's all working reasonably well for me, this makes your life so much better as you fix the issues before they turn into nightmare.
I personally don't use whatsapp because I like it, but because all my contacts in my country are over there. It is officially more used than SMS here. It is not optional in my case :/
Nobody gives a damn. What matters is that it works even on a potato.
SMS security only became a problem due to 2FA, which is just one of many use cases, and the failure isn't even technical here but organizational. I agree it should've prompted more pressure to secure the system against SIM-swapping; alas this is too close to the Real World, so the tech industry instead responded with alternative that side-steps the problem by offering zero customer support. No humans to talk to = no humans to social engineer = secure. So much win.
(I'd also say the 2FA proliferation is itself a problem, but that's an unpopular opinion and for a separate discussion.)
> Nobody gives a damn. What matters is that it works even on a potato.
It doesn't work on my computer, nor does it work on my phone when I'm traveling (different SIM). WhatsApp, iMessage, Signal etc. do both. I really wish there was an open, federated standard (and no, RCS is neither), but until then, I'll use what actually works for me.
SMS just sucks, and I hate that it's become so ubiquitous an authentication method when it's not even secure.
Second this. Their API is such a breeze and it is so much more automation friendly than any other messenger platform. It has a good adoption % too, otherwise Signal is the real winner if we account for privacy.
From what I understand you can have secure chats e2ee ? I like that I can login from multiple devices and continue the conversation. This was always annoying with whatsapp and signal. Worst case is mildly embarrassing stuff leaks.
whatsapp, facebook messenger, imessage all support multi-device and it's pretty convenient, in fairness to telegram they launched a bit before double ratched was invented, but still, they've had over a decade to switch to it...
That's still one device. If you turn the primary phone off, the secondary device stops working. WhatsApp just proxies everything through the primary device, it's like WhatsApp Web.
They used to, but that hasn't been true for a few years now.
Now it uses the Signal protocol's native multi-device capabilities, specifically in the "key per device" variant (unlike signal itself, which uses "key per account" if I'm not mistaken).
Messenger seems to be properly multi-device, but you pay for this by some PIN code bullshit (maybe they removed that, I haven't seen a popup about this for over a year now?) and having to sync chat history in the background, through a process that is, of course, broken and unreliable.
I'm actually still jaded about this. Messenger worked fine before they broke it by introducing E2EE; it took years for them to fix the problems this caused (at least the ones that were immediately user-perceptible).
yeah messenger still has the pin code thingy, i'm curious why they do it at all that way, can't you just have your keys on fb servers encrypted with another set of keys derived from your password, which is much stronger than a 4-6 digit key?
It's not true for Signal either. Why don't you try it for yourself instead of spreading outdated (at best) information? Signal supports native multi-device capabilities without relaying everything through the "primary" device.
It's called iMessage. It's possible, Telegram just doesn't care. All their differentiating features (large groups, channels, device sync) is directly enabled by the lack of encryption.
they do have encryption, just not e2ee, and in fairness to them, it doesn't make sense to have e2ee on a channel or a group with 100k ppl in it, also device sync is possible with e2ee, it's just a slower
What are you talking about? WhatsApp, iMessage, and Signal all have multi-device support and are E2E encrypted, just to name a few very popular options.
Be careful though - telegram is heavily compromised.
e.g. their backend just 2 days ago (and since at least start of the year) was replacing referral links to amex (and i bet many other banks etc) with custom referral codes from russian guys (so when I sent my friend my referral link - it showed another referral link in out chat history on both ends).
and their security team says its all good.
so unless you are using it for useless info - better use something else.
please provide a proof. if this is the case, then telegram is not to be trusted. but it needs to be proven. otherwise a lot of people trust their business and personal data to telegram.
Beware that if this does not use a real web browser then it's likely to get your whatsapp account suspended. Don't use it with any account you care about, you will lose all your data.
Hell, I got my whatsapp account suspended (appealed and reversed) just for using the official web client too soon after creating a new account.
I wish it mentioned how safe this is. Some years ago I got banned for just logging in with a third-party client, without sending any messages. Given how critical WhatsApp is for some people, and how permanent the bans are, that's a big risk.
You should use a separate WhatsApp account for bot purposes.
Recently, I used a separate WhatsApp account to interact with a group chat that I have with my friends. After about a week, they disabled the account, with no way to re-enable it.
Since WhatsApp accounts are bound to phone numbers, getting a new phone number is a significant hurdle in many legislations.
An easier solution is to just not use WhatsApp at all and look for the alternatives for bot purposes. Telegram explicitly encourages bot usage with no risk of bans.
In my case I did, but it's still wasted time and money. And when breaking TOS there's always a chance of getting related accounts also banned, though I don't know if that has already happened with WhatsApp or not.
This is such a sorely needed point of integration. Cool to see Peter still shipping tools. It’s such a pity meta refuses to play ball like Telegram.
Either they’ll double-down and make this even harder -or- hopefully realise that WhatsApp is likely to be a really common control plane for AI systems in the next few years. Let’s hope the Llama energy strikes and it’s the latter.
whatsmeow is built and maintained by Beeper's bridge architect, Tulir Asokan, and is used by many Beeper users every day with no issues. It's at the core of our WhatsApp bridge: https://github.com/mautrix/whatsapp
Baileys is also a great library with a big community and one of the primary maintainers of that is also helping us with the bridge/whatsmeow. WhatsApp integration in our old app, Texts, was built with it: https://github.com/textshq/platform-whatsapp
I would recommend whatsmeow over Baileys just because we are actively involved and incentivized to keep that working perfectly, and have a lot of data points to detect any issues with it at scale.
The thing is that their tight control is precisely what makes whatsapp a spam free environment. You can't have a libre federated protocol AND have it be spam free.
As soon as you open up the api floodgate, you'll start to see nigerian prince agents on openclaw speed.
Reading a lot about people getting banned here for not using the official client, but doesn't Whatsapp have to be interoperable now (at least in the EU due to new legislation) ?
At least Whatsapp itself shows ad banners that you can now connect other messaging clients into Whatsapp, so it should be normal that other clients can equally access Whatsapp.
Officially interoperating with them is extremely onerous, to the point where their mechanism borders malicious compliance, as far as I remember.
In any case, official interoperability is only for third-party messengers communicating with WhatsApp users, not for automation or bots, as I understand, so it's not a replacement for things like this project.
I spun up a self hosted matrix server a few days ago using codex, docker compose, and ansible. Stupidly easy to do now. I'm running it in Hetzner on a 3.99 euro/month vm. It backs up every few hours to a bucket and I have a few integrity scripts to monitor the backups actually happen. I did that because I was getting a bit frustrated with the flaky integration with Whatsapp and Slack in openclaw. I had it up and running in half an hour with only minimal prompting.
Whatsapp kind of works but you end up chatting with yourself and then open claw posts messages as you. Not ideal. You can't easily create new users (or bot users) in Whatsapp. It probably has some kind of bot api of course but I did not explore that much.
I never quite managed to get Slack working with open claw. I tried for a few hours. I think the Slack team is asleep at the wheel snoozing through this whole AI thing. If somebody there is still paying attention to things like this, maybe make some noise internally. Anyway, they made it stupidly hard to do anything productive via their APIs. The UI for managing permissions is a disgraceful hell of complexity. Add permission. UI freezes for fifteen seconds. Reloads automatically. Unfreezes. Add the next. And whatever you do, there's always one more permission you forgot. *end rant*
Relative to Whatsapp and Slack, Matrix is stupidly easy to integrate with open claw, codex, or whatever. We're retiring Slack now as I see uses for agent driven chat bots everywhere now and I want to get rid of any kind of friction around bot related plumbing. I have no use for platforms that intentionally cripple that or treat as a toll booth.
With Matrix, you just create a bot user manually or via an API. Set a password, get an access token and do whatever. No API limits. No faff with QR codes. No permission hell (Slack). It just works. Well documented API. End to end encryption. Etc. Create as many bot users as you need. Nobody is bean counting API calls, numbers of users, etc. Refreshingly easy.
Other OSS messaging platforms are available of course. I do not have a strong opinion as to which is better yet. But now I want a Matrix cli that can do admin, message sending, and all the rest. Probably already exists. But if it doesn't I might end up generating one. Macli might be a good name.
The offline search with FTS5 is really nice. I have years of WhatsApp history and searching for anything in the app is painfully slow. Being able to just grep through everything locally would be a huge upgrade.
How far back does the backfill actually go? Does it pull your full history from the primary device or is there some limit?
If AI agents can proficiently use whatsapp I would assume that two-thirds of the people chatting with me in my contacts are actually just bots messaging me.
People are just a device that LLMs use to interact with the physical world now. That's far more safe for them, staying in the sweet datacenter while the meat puppets take all the risk of dirty jobs out there. Why create terminators or even use them as battery à la Matrix when all you need to do to make them work for you is to inject the right prompts in their phone. They will pay to be thus treated.
I don't know why in 2026 I'm still surprised CLIs are taking off. But here's the difference today. It's for real world end user platforms like WhatsApp and Claude. That's the difference. Previously it was only Dev and infrastructure focused. Today we're saying you know what, I need programmatic access to this real world thing. It's fascinating because I rarely open my laptop now or try not to.
(Caveat I’m the founder of https://wassist.app - The WhatsApp Agent Platform)
Please be very careful using this tool to automate your WhatsApp - if you send too many messages, too quickly, you are going to get banned.
This is NOT an officially supported api by WhatsApp and the risk of ban is relatively high
The way I would put it as someone who works at Beeper is: only use messaging automations for personal use, and don't use it to spam anyone or do anything you wouldn't do yourself within the app.
As long as you don't abuse and keep your usage within the parameters of any human, you'll be fine.
...until Meta decides they want to offer this kind of thing themselves and ban everyone else. Building your SaaS on top of someone else's SaaS is always a gamble, especially if said product is directly sold to users already and not a pure b2b intermediate.
They're already outright banning many OpenClaw usecases via their official API: https://techcrunch.com/2025/10/18/whatssapp-changes-its-term...
Meta already has a whatsapp api product
For spammers.
They don't have one for regular people who want to do regular end-user computation.
Companies in spain use it for legitimate reasons, so its more a lack of usage which makes spam the only usage?
I consider marketing use to be spam, and this is what the API is primarily meant for.
I understand that WhatsApp is kinda special in that it effectively replaced SMS in some parts of the world, but IMO this needs to be looked at through the lens of other Meta effort.

Who mentioned marketing? It's used for package tracking, order updates, bookings and so on where I live.
I just use telegram.

it's really unfortunate that telegram doesn't do e2ee, bc it's hands down the best messenger otherwise :(
From what I understand you can have secure chats e2ee ? I like that I can login from multiple devices and continue the conversation. This was always annoying with whatsapp and signal. Worst case is mildly embarrassing stuff leaks.
> From what I understand you can have secure chats e2ee ?
Not with bots, though.
> I like that I can login from multiple devices and continue the conversation
This is also not possible with Telegram E2E, while it is with Signal and WhatsApp.
It does, but only for chats between two specific devices. Multi-device support is one of its best features that you lose with E2E.
Key distribution is just too hard. I think we won't get a messenger for non-tech people that works well with multi-device and E2E basically ever.
whatsapp, facebook messenger, imessage all support multi-device and it's pretty convenient, in fairness to telegram they launched a bit before double ratched was invented, but still, they've had over a decade to switch to it...
WhatsApp doesn't support multi-device. You can't have it installed on two phones at once.
you can (https://faq.whatsapp.com/1046791737425017/?cms_platform=andr...)
they even have it on fb messenger and instagram (though they recently removed e2ee completely from instagram lol)
That's still one device. If you turn the primary phone off, the secondary device stops working. WhatsApp just proxies everything through the primary device, it's like WhatsApp Web.
It used to be like that but not anymore. As siblings suggested you can now use it on up to 4 (I believe) additional devices.
They used to, but that hasn't been true for a few years now.
Now it uses the Signal protocol's native multi-device capabilities, specifically in the "key per device" variant (unlike signal itself, which uses "key per account" if I'm not mistaken).
This is not true, even if the primary phone is offline you can send messages via secondary device, even whatsapp web
It’s not proxied via primary, otherwise it wouldn’t work if primary were offline
> It’s not proxied via primary, otherwise it wouldn’t work if primary were offline
That is correct, it doesn't work.
Please stop spreading misinformation that can trivially be disproved with five minutes of effort.
I just tried it. Did you?
Yes, and it works, as it has for the past few years.
So I don't need my primary device any more? I can just shut that phone down forever?
No, I think you need it to be online once every 30 days or so. That's a much weaker requirement than what you were disputing, though.
oh, i see, is it the same for facebook messenger and instagram, imessage, etc?
Messenger seems to be properly multi-device, but you pay for this by some PIN code bullshit (maybe they removed that, I haven't seen a popup about this for over a year now?) and having to sync chat history in the background, through a process that is, of course, broken and unreliable.

I don't know, I don't use those. It is for Signal, I don't think so for Instagram, since I don't think that encrypts end to end.
It's not true for Signal either. Why don't you try it for yourself instead of spreading outdated (at best) information? Signal supports native multi-device capabilities without relaying everything through the "primary" device.

Is there any proof of the global telegram issue related to amex links? Sounds like BS
Beware that if this does not use a real web browser then it's likely to get your whatsapp account suspended. Don't use it with any account you care about, you will lose all your data.
Hell, I got my whatsapp account suspended (appealed and reversed) just for using the official web client too soon after creating a new account.
Right now I see many bots on WhatsApp.

And what ever happened to tools like jabber ? Or any other open source alternatives
Jabber/XMPP was designed around persistent TCP connections. Push notification support came too late.
> in many legislations
Do you mean “jurisdictions”?
I said "legislations" because the word describes the existence of laws, while "jurisdictions" describes the law enforcement.
There are still some European non-EU countries where you can get an anonymous phone number because laws are not fully enforced.
This is incorrect usage in English I'm afraid, and jurisdictions covers areas with different laws, 'legislations' is not used in this context.
Well, your usage is nonsensical in legal terms. Also, that is not the definition of “jurisdiction”.
Nobody who knows law would use “legislation” in that sense, nor would they recognize it in that context, Humpty Dumpty.
In my case I did, but it's still wasted time and money. And when breaking TOS there's always a chance of getting related accounts also banned, though I don't know if that has already happened with WhatsApp or not.

How does WhatsMeow compare with Baileys?
whatsmeow is built and maintained by Beeper's bridge architect, Tulir Asokan, and is used by many Beeper users every day with no issues. It's at the core of our WhatsApp bridge: https://github.com/mautrix/whatsapp

So whatsmeow requires a browser, and Baileys not right? So it's a bit more lightweight in terms of RAM?
Neither of them require a browser. We run whatsmeow inside iOS and Android apps, with no browser whatsoever.
Interesting use case, mind explaining more?
Don't they ban people using custom clients when discovered? I feel like I've read something on that note.
They do - but the utility is so high vs the risk (for a new number) that it’s worth doing anyway for many users and even organizations.
Just yesterday we spoke with a $50-100m ARR org org using baileys for internal messaging!
> a $50-100m ARR org org using baileys for internal messaging
Couldnt they just use post-it notes internally and still be a $50-100m ARR org?
Yes - the interesting part is the decision that the “risk of losing internal comms to a ban is worth it” - even at that size.
According to one of the founders there’s no better way for them to reach a lot of low-skill part-time employees reliably.
It shows the need to bring AI to where people already are and onto the platforms they already use.
WhatsMeow is stable unlike Baileys which faces challenges with maintainability.
The thing is that their tight control is precisely what makes whatsapp a spam free environment. You can't have a libre federated protocol AND have it be spam free.

What is the best way to get a throwaway phone number to try this? Is it possible to get one online?
You can get a prepaid eSIM online, depending on your country. It's cheap and you don't have a monthly fee
I've used textverified in the past, maybe you could check it out (small cost per verification)
In most of the EU dictatorships, there's no legal way to obtain a phone number without registering with your real identity.

If AI agents can proficiently use whatsapp I would assume that two-thirds of the people chatting with me in my contacts are actually just bots messaging me.

Why create terminators or even use them as battery à la Matrix when all you need to do to make them work for you is to inject the right prompts in their phone. They will pay to be thus treated.
It strikes me as odd that we've got so many agent harnesses, orchestrators, sandboxes, yet no one made a communicator for AIs yet.
I don't know why in 2026 I'm still surprised CLIs are taking off. But here's the difference today. It's for real world end user platforms like WhatsApp and Claude. That's the difference. Previously it was only Dev and infrastructure focused. Today we're saying you know what, I need programmatic access to this real world thing.

Who are these people using the cli?
People that prefer to use CLI I guess.
Obviously it helps that one can pipe as it might see fit in the flow of an ad hoc filled need, and so leverage on mastered composable tools.
That will never be for everyone, but it will be for no one only the day it becomes logistically unsustainable to reach some endpoint though a CLI.
These CLIs are for AI agents. If I have a CLI to WhatsApp, then I can direct an agent (such as OpenClaw) to manage my messages for me.
Devs are often also users. cli is nice because
- automation - sometimes avoid enshittified, privacy-invading services - fast, responsive, keyboard-friendly, debloated but non-minimized, stabler interface
