Preparation Before Onboarding a Business App number
Meta now supports "Coexistence", allowing you to run the WhatsApp Business App and WhatsApp Cloud API side by side. This newly launched feature — though still under active development — 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.
💡 Please note that WhatsApp Coexistence is available only to businesses actively using the WhatsApp Business App, based on Meta’s review of account age and messaging quality.
Before onboarding a Business App number, please ensure you have the following items prepared:
1. Prepare a Meta Business Account
You can either create a new Meta Business Account or connect an existing one during the Embedded Signup process. Please choose your Business Manager wisely—once your number is registered, you cannot change it.
💡 Important: The Business Manager must be owned by the company sending messages. Adding users from other organizations can lead to your Business Manager being blocked. In Business Manager Settings > Business Info, be sure to enter all of the following under your Business Manager profile:
- Legal Name of your company
- Business Address
- Website URL
- Phone Number you will use for messaging
Incomplete or inaccurate information may prevent successful registration.
2. Pre‑Onboarding Checklist
Before you begin, please ensure:
You’re already actively using the WhatsApp Business App with this number for at least 7 days.
WhatsApp Business App is version 2.24.17 or later.
Your business must not be registered in a currently unsupported country (as listed here).
Once all checks are complete, you’re ready to get started! Please refer to the Onboarding an existing Business App number guide for more information.
