This guide explains how Coexistence works: the option that allows you to use the same WhatsApp number on the mobile app and in the Cloud API (Jelou) simultaneously.

​
What is Coexistence?

Coexistence allows the same number to work at the same time in: 📱 WhatsApp Business App (mobile) ☁️ WhatsApp Cloud API (Jelou) This means you can:
  • Send campaigns and automations from Jelou
  • Continue using the app for manual 1-to-1 support
  • Keep the history synchronized between both environments

​
How does it work?

During the channel connection:
  1. The business enters its current WhatsApp Business App number.
  2. Meta sends a verification code.
  3. The user confirms the connection from the app.
  4. The user can optionally authorize sharing:
    • Message history
    • Contacts
Once completed:
  • The number is connected to the Cloud API
  • Jelou can send bulk and automated messages
  • The app continues working normally for manual support

​

What happens during synchronization

Once the number is registered: You have 24 hours to:

The app must:
  • Remain open
  • Have a stable connection
📌 The process may take several minutes depending on the volume of messages.

​
History states

The business can decide: ✅ Share history
Messages of up to 180 days are synchronized. ❌ Do not share history
Jelou receives the event, but not the previous messages.

​
Events received by Jelou (webhooks)

To maintain synchronization, Jelou listens for events such as: account_update
