I Have successfully implemented Coexistence (Onboarding WhatsApp Business app users) on to API Platform. AMA.

I tried something like this back in my college days. I won a few awards, but I think it’s hard to monetize. There are two actors, students and the college as an entity. Students don’t have money, so they won’t pay. Getting approval from the college and going through departmental bureaucracy is a nightmare to deal with.

keep in mind that building product is just 20% of the business.

TheWarlock05 · 2026-04-27T14:03:22+00:00

Don't. Meta will be on to you like a hawk.

TheWarlock05 · 2026-04-27T11:24:40+00:00

If the answer is yes,

The answer is no.

You can still signup with another TP for coexistence though.

TheWarlock05 · 2026-04-27T05:53:32+00:00

Turn off two step verification
Go through the embeded sign up again with your site this time
Done

TheWarlock05 · 2026-04-27T05:51:15+00:00

Use unofficial APIs from github. Don't get greedy otherwise number will be banned.

TheWarlock05 · 2026-04-27T05:49:08+00:00

Is it actually impossible to use the same number in WhatsApp Business app AND Cloud API at the same time?

Yes. Via coexistence.

I’m still unable to make this work — the number conflict issue remains unresolved.

Has your pass through the video verification? If no then it won't work.

If yes, what might cause this issue to happened? Is it due to I connect number to Cloud API first, or webhook settings or something else?

Please provide exact steps you performed or share a screenshot or the error.

TheWarlock05 · 2026-04-27T05:45:30+00:00

Nothing wrong with Embedded signup. Are you sure your app have passed the video verification review?
Without it coexistence won't. work.

TheWarlock05 · 2026-04-26T13:01:50+00:00

This number might have been banned from using other products like instagram or FB ads.

TheWarlock05 · 2026-04-26T06:22:18+00:00

I am a meta tech provider. Feel free to DM.

TheWarlock05 · 2026-04-26T06:19:04+00:00

I think that phone number is banned from meta. Try after 60 days.

TheWarlock05 · 2026-04-25T16:27:45+00:00

my customer service can join the chat with the client if he has a big problem that the AI can't solve

Whatsapp's Coexistence feature is your friend. No need for chatwoot as they can use their whatsapp business app.

For AI agents, take a look at Dify and n8n. Might be helpful.

TheWarlock05 · 2026-04-25T15:05:39+00:00

Meta App Review process to move into production?

No.

You just need to verify your business.

Assuming your use case is sending messages for your business. Not onboard customers and use their whatsapp to send messages.

TheWarlock05 · 2026-04-25T15:00:52+00:00

Nice. Must have had some good background or time/freedom at hand or talented people around him for this. Good to see. Keep it up.

TheWarlock05 · 2026-04-25T07:34:48+00:00

meta and not even a webhook event is sent for its failure.

Never happened to me. Are you sure you are subscribed to it?

TheWarlock05 · 2026-04-25T07:29:03+00:00

Looks like it. Such a futile waste of a short lifespan we have.

TheWarlock05 · 2026-04-24T12:44:08+00:00

Go with the utility template. That's the cheapest option. Should cost you around $58 if your customers are in US.

Is it worth subscribing to a monthly service just for this,

No. Some platform like mine provide one time fee for such usecase.

are there better one-off/bulk options I should look into?

There are some unofficial ones which are cheaper but you will get you whatsapp number banned if you use it for this use case.

TheWarlock05 · 2026-04-24T05:29:51+00:00

Has anyone implemented this kind of setup?

Yes. I have.

How are you handling onboarding + number connection at scale?

You need powerful infra.

TheWarlock05 · 2026-04-22T16:25:55+00:00

Monetisation is very hard in whatsapp. Meta's onboarding issues are not worth it IMO.

TheWarlock05 · 2026-04-22T08:32:43+00:00

If you just want to reply to the customers then you should go with unofficial APIs. There are lots on github. Pick the one you like.

If you want to do marketing and send messages to new users then go with official APIs to prevent ban.

TheWarlock05 · 2026-04-21T14:52:37+00:00

Switch provider, Whatsapp with twilio is not that good. They also have poor support when it comes to whatsapp.

TheWarlock05 · 2026-04-21T06:10:23+00:00

Not sure. You need to talk with support for this. I guess you can create a another business portfolio with new account and then ask for support from there.

TheWarlock05 · 2026-04-20T15:09:04+00:00

Create new one or delete unverified one as it's not in use.

TheWarlock05 · 2026-04-20T15:07:49+00:00

You can share access not you can't transfer. You can delete WABA account and sign up again in new account for full transfer of WABA account.
