The Best of Both Worlds
Coexistence mode lets you keep using the WhatsApp Business App while simultaneously gaining access to the full power of the official WhatsApp Business API.
Keep Your Number
No need to change your phone number or migrate to a new account. Your existing WhatsApp Business number works for both App and API.
Preserve Chat History
Switch to Coexistence mode and keep up to 6 months of chat history synced between your Business App and API platform.
Both Work Together
Messages sent via the API appear in your Business App and vice versa. Real-time sync ensures your team never misses a conversation.
Three Steps to Coexistence
Keep Your WhatsApp Business App
No need to uninstall or reset your existing WhatsApp Business App. Your number and chat history stay intact.
Connect to Official API via Resayil
Use Meta's Embedded Signup to connect your number to the WhatsApp Business API through Resayil in minutes.
Both Platforms Work Simultaneously
Your Business App and Resayil's API platform run in parallel. Reply from either — messages stay in sync.
