Official Meta Tech Provider
What is a WhatsApp Business Solution Provider?
A WhatsApp Business Solution Provider (BSP) is a company officially authorized by Meta to give businesses access to the WhatsApp Business Platform — the Cloud API. OmniChatStack is an official Meta Tech Provider, so you get verified, compliant WhatsApp access, plus one shared inbox for every channel, without building on Meta's API yourself.
Working through an official provider means your account is compliant, your number stays yours, and you get the tools Meta's raw API doesn't include on its own — a shared team inbox, AI, broadcasts and automation — in one place.
100% Compliant

WhatsApp Coexistence
What happens to your number when you connect?
Nothing changes about your number. OmniChatStack uses official WhatsApp Coexistence, so you keep using the WhatsApp Business App exactly as you do today — and your team also works the same number from a shared inbox on the desktop. Link your existing number in minutes, or transfer it in if that’s a better fit.
Honest note: When you connect via Coexistence, the last 6 months of individual (one-to-one) text messages sync into OmniChatStack, and future 1:1 chats keep syncing both ways. What does not sync: photos, videos, locations, and group messages.
Trained AI Assistant
Answers that sound like your business
The AI answers common questions in English, Urdu and Roman Urdu, trained on your own site, PDFs and FAQs — and hands off to a person when it should.
Unified Shared Inbox
Every channel your customers already use — in one place
WhatsApp, Instagram, Facebook, email and webchat land in the same inbox, so nothing gets missed and no one’s guessing what a colleague already answered. New conversations are assigned automatically, and AI is live on every channel — not just WhatsApp.
Broadcasts & Campaigns
Segmented, scheduled WhatsApp broadcasts on Meta-approved templates.
Automation & Flow Builder
Drag-and-drop reply flows that answer the questions you get every day.
Developer API
Send and receive WhatsApp messages from your own app, if you'd rather build than click.
Templates & Catalogue
Manage WhatsApp templates and show your products, right inside the chat.

No. WhatsApp Coexistence lets you keep using the Business App on your phone exactly as you do today, while your team also works the same number from OmniChatStack’s shared inbox.
Will I lose my current chat history?+−

It handles common questions well — trained on your own content, answering in English, Urdu and Roman Urdu — but it hands off to a person whenever a conversation needs one. It’s not meant to run unsupervised.

Connecting your number and channels takes minutes, not weeks — no developer required. Most teams are answering their first shared-inbox conversation the same day.
