The best of both worlds

You no longer have to choose between the app and API

Traditionally, moving a business number to Cloud API meant changing how staff handled everyday conversations. WhatsApp Coexistence is designed for eligible WhatsApp Business app users who want to add Cloud API capabilities without giving up the app they already know.

With WebWMS2U, your team can continue responding through the WhatsApp Business app while your business gains access to automation, campaigns, API connections, webhooks and reporting.

Frequently asked questions

WhatsApp Coexistence FAQ

It is Meta's supported method for eligible businesses to connect an existing WhatsApp Business app account and phone number to the WhatsApp Business Platform Cloud API while continuing to use the Business app.

Yes, this is the main advantage of Coexistence. Your team can continue using the Business app while WebWMS2U handles supported Cloud API messaging and automation.

Chat and message availability depends on Meta's supported history-sharing and synchronisation behaviour, the permissions selected during onboarding and the WebWMS2U features enabled for your account. Confirm your history requirements with us before setup.

Meta charges may apply to messages sent through the WhatsApp Business Platform according to Meta's current pricing and message rules. WebWMS2U subscription and message-credit charges are separate.
