WhatsApp Coexistence: Run the Business App and the API on One Number

Coexistence lets a business use the WhatsApp Business app and the WhatsApp Business API on the same phone number — so owners and staff keep chatting from the familiar app while automation, broadcasts and a team inbox run through the API.

Keep the WhatsApp Business app you already use AND add API automation on the same number — no number change, and you choose whether to bring up to six months of one-to-one chat history across.

Why it matters

Many Indian SMBs run their whole business from the WhatsApp Business app and fear that 'going API' means abandoning it. Coexistence removes that fear: staff keep replying from the app they know, while the API layer adds broadcast, chatbots, a shared inbox and integrations on the very same number. It's the smoothest possible on-ramp from app to platform.

Where many CPaaS fall short

Providers that force a number migration and app cut-over create friction and downtime. Coexistence support is a real onboarding differentiator — InfiQ supports it.

Frequently asked questions

Can I keep using the WhatsApp Business app?+
Yes — that's exactly the point of coexistence. Your staff keep replying from the familiar Business app while the API adds automation on the same number.
Does coexistence use the same phone number?+
Yes. Both the WhatsApp Business app and the WhatsApp Business API run on one and the same phone number, so there is no number change for you or your customers.
Will I lose my existing chats and history?+
No. Your chats stay in the WhatsApp Business app, and you can choose to bring up to six months of one-to-one history into InfiQ (media files for the last 14 days; group chats aren't imported). Meta recommends backing up your chats first.
Is coexistence available for my business right now?+
Indian (+91) numbers have been eligible since May 2025, and Meta added the UK, the EU and more in October 2025. Meta also checks your number's activity on the app, and its signup tells you before anything changes if your number doesn't qualify yet.
Do I have to migrate my number to go API?+
No. Coexistence avoids a forced number migration and app cut-over, so you get API power without the friction and downtime other providers create.
Is InfiQ an official partner for this?+
Yes. InfiQ is an official Meta Business Partner and supports coexistence so you can add broadcast, chatbots, a shared inbox and integrations on your existing number.
