Onboard an existing Business App number ​

From now on, you can connect your existing WhatsApp Business Account to ChatBooster without deleting the existing account with ChatBooster, using Meta's latest "Coexistence" solution!

💡 Please note that this newly launched feature may contain occasional bugs, isn’t supported in all countries, and has a few limitations compared with using the Cloud API alone.

If your business isn’t already using the Business App extensively, we recommend 👉 onboarding a brand-new number directly to the Cloud API for the smoothest experience.

Before you get started, make sure you have all the pre-requisites ready
