WhatsApp Coexistence: Use the Business App and API on the Same Number

What is WhatsApp Coexistence?

For a long time, moving to the WhatsApp Business API meant giving up the WhatsApp Business App on that number. Coexistence changes this. It lets you connect your existing Business App number to the WhatsApp Business Platform and keep using the app on your phone at the same time.

In simple words: you keep chatting from your phone as before, and your business also gets API features like campaigns, chatbots, a team inbox and integrations – on the same number your customers already know.

Who is Coexistence for?

• Businesses whose customers already know their WhatsApp number.
• Owners who like replying from their phone but need automation and a team inbox.
• Businesses that tried to switch before but didn’t want to lose the app.

What you keep

• Your existing number and business name.
• The Business App on your phone for day-to-day chats.
• Your contacts, so customers don’t need to save a new number.

What you add

• Campaigns with approved templates, buttons and media.
• Chatbots and AI replies for common questions.
• A shared team inbox so more people can help customers.
• Integrations with your CRM, store and forms through the API.
• Reports on campaigns and conversations.

What changes

Coexistence is powerful, but a few things work differently from the app-only setup. Messages you send through the API follow API rules – templates to start conversations and Meta’s per-message charges for templates. Some app features may behave differently once the number is connected. Meta updates Coexistence over time, so check the current details in your panel or ask our team before you connect.

How to connect with WATick

Tips for using both together

• Decide who replies where – for example the owner on the phone, the team in the WATick inbox.
• Use chatbots for FAQs so both sides handle fewer repeated questions.
• Keep marketing on the API with opted-in lists, templates and reports.
