The single most common objection to the WhatsApp Business API used to be: "But my team lives in the WhatsApp app — we can't give it up." Historically, registering a number on the API killed the app on that number. WhatsApp Coexistence, a Meta feature now rolling out through Business Solution Providers, removes that trade-off: the same number runs in the app and on the API simultaneously.
What Coexistence actually does
Your team keeps chatting 1-to-1 from the WhatsApp Business app on their phone, exactly as today
Simultaneously, the API layer powers broadcasts, chatbots, automation and integrations on the same number
Chats sync — conversations started by the bot or a campaign are visible in the app, and app chats appear in your platform inbox
Contacts see one number and one brand thread; nothing changes on their side
Who Coexistence is for
Small teams emotionally (and operationally) attached to the app's simplicity
Owner-led businesses where the founder wants chats on their phone at night
Businesses migrating gradually — automate campaigns first, move support to the shared inbox later
Field teams that need the mobile app while the office runs the platform
Current limitations to know
Availability is rolling out gradually — not every WABA/number combination is eligible yet; your BSP checks eligibility during onboarding
Some app features (like communities) and some API features may behave differently while paired
Message history from before pairing may not fully sync into the platform inbox
One number still means one display identity — team accountability is far better in the shared inbox than in the app
How to enable it with Sendvise
Tell the onboarding team you want Coexistence during signup (or ask support if you're already live)
Keep the WhatsApp Business app installed and active on the primary phone
Complete the pairing flow — a QR/OTP handshake links the app to the API registration instead of replacing it
Verify sync by sending a test message from both sides
Not eligible yet? The standard path still works: register the number on the API and run everything from the platform — most teams stop missing the app within a week of using a proper shared inbox. Compare both approaches in our API vs App guide.
FAQ
Does Coexistence cost extra?
No platform surcharge on Sendvise — normal plan pricing and the standard published per-message rates apply.
Can I undo the pairing?
Yes. You can separate the number back to app-only or API-only; your BSP handles the deregistration order safely.
Do customers see anything different?
No — same number, same chat thread, same history on their phone.
Is this an official Meta feature?
Yes. Coexistence is Meta's own capability delivered through official BSPs — it is not a hack or a third-party mod.
