Frequently Asked Questions

Everything you need to learn about WhatsApp Co-Existence

What is Coexistence & How It Works

What is WhatsApp Coexistence, and how does it work?

WhatsApp Coexistence is a Meta feature that lets you use your WhatsApp Business App and Cloud API simultaneously on the same number. Messages sync automatically between both platforms through a system called "message echoes"—so conversations started in the app appear in your API dashboard and vice versa.

Will my customers notice any difference with WhatsApp Coexistence?

No. From your customers' perspective, nothing changes. They message the same number and get the same experience—they won't know whether you're replying from the app or the API.

Can I keep using the WhatsApp Business App as usual for everyday chats?

Yes. You can continue using the WhatsApp Business App normally for day-to-day customer conversations. The app stays active on your phone while the API handles automation, broadcasts, and integrations in the background.

Setup Requirements

Does WhatsApp Coexistence work with my regular WhatsApp account?

No. WhatsApp Coexistence only works with the WhatsApp Business App, not the consumer WhatsApp app. You'll need to have your number registered with the WhatsApp Business App and added to your Meta Business Manager before onboarding.

Can I use my existing WhatsApp number, or do I need a new one?

You can use your existing WhatsApp Business App number—that's the whole point of Coexistence. No new number needed, no customer-facing changes.

How long does the setup and chat syncing process take?

The onboarding itself takes just a few minutes. However, syncing your chat history and contacts can take up to 6 hours depending on the volume of existing data.

What happens to my existing chat history when I enable WhatsApp Coexistence?

Your chat history syncs automatically. Up to 6 months of past conversations from the WhatsApp Business App will be available in your API integration and ZEPIC dashboard.

Features & Limitations

Which features are lost or restricted when Coexistence is enabled?

Some features are disabled or not synchronized: broadcast lists (use API templates instead), live location sharing, disappearing messages in one-on-one chats, message revoke, view once messages, and group chats won't sync between app and API.

Can my team reply from their phones using the app even if the API is active?

Yes. If a conversation was started from the API, your team can switch to the app for quick replies and it will remain part of the same (free) service conversation. This flexibility is one of Coexistence's main benefits.

Will automated messages from the API show up in my WhatsApp Business App?

Yes. All messages sent via the API—including automated campaigns, broadcasts, and template messages—appear in your WhatsApp Business App, so you always have full visibility of customer conversations.

Pricing & Costs

Does using WhatsApp Coexistence cost extra?

No. The Coexistence feature itself is free. You only pay for Cloud API usage based on Meta's standard conversation pricing. Messages sent through the WhatsApp Business App remain completely free.

How are messages billed in Coexistence mode?

WhatsApp Business App messages are always free and unlimited. API messages in 24-hour windows are billed by category (Marketing, Utility, Authentication). User-initiated conversations (Service) are free and unlimited as of November 2024.

If I reply in the app to an API-initiated chat, am I charged twice?

No. If a conversation was started from the API, you can switch to the app for replies and it stays as the same service conversation—no duplicate charges. Just avoid sending the same message through both channels.

Important Restrictions

Can I get the verified blue tick badge with WhatsApp Coexistence?

No. Meta currently doesn't allow Coexistence-enabled API numbers to apply for the Official Business Account (blue tick) badge. If verified status is critical for your business, consider standard API integration without Coexistence.

Can I add the WhatsApp Business App to my existing API number?

Not currently. Coexistence onboarding only works in one direction—from Business App to API. If your number is already connected to the API, you'll need to disconnect it first, reinstall the Business App, and then re-onboard with Coexistence enabled.

Is WhatsApp Coexistence available in my country?

Supported countries include India, Mexico, Brazil, Indonesia, USA, Hong Kong, Singapore, and many others. Currently NOT supported in: European Union (EU), United Kingdom (UK), Russia, and some other regions. Contact our support to confirm availability in your region.

Maintenance & Disconnection

How often do I need to open the WhatsApp Business App?

You must open the WhatsApp Business App at least once every 14 days to keep your Coexistence setup active. If you don't, the connection may be disrupted.

What if I want to stop using WhatsApp Coexistence?

You can disconnect anytime, but doing so will deactivate your Cloud API access. Your WhatsApp Business App will continue working normally with all your chat history intact.
