WhatsApp Business API vs Coexistence

The difference between WhatsApp Business API and Coexistence is how the phone number is used. In an API-only setup, the number runs through Flovoo and can’t be used on the WhatsApp Business app. Coexistence lets you use the app and Flovoo together on the same number, with contacts and the last 6 months of conversations synced.

Businesses today rely on WhatsApp as a main channel for talking to customers, and usually choose between two options: WhatsApp Business API or WhatsApp Coexistence.

The key difference is how the phone number is used, and whether you can keep using the WhatsApp Business app after connecting.

Diagram titled "Choose the WhatsApp setup that fits your business needs": a balance weighing WhatsApp Business API, with a dedicated phone number and the app not usable, against WhatsApp Coexistence, with a shared phone number and the app still usable.

What Is WhatsApp Business API?

WhatsApp Business API suits businesses that want to scale customer communication and rely on automation.

In this setup, the phone number runs entirely through Flovoo and can’t be used on the WhatsApp Business app.

Key Features

  • Manage the number entirely from Flovoo, without needing the app on your phone.
  • Teamwork, with several team members replying from the same number.
  • Automation, such as AI agents and workflows.
  • Send message templates and campaigns.

What Is WhatsApp Coexistence?

WhatsApp Coexistence lets you use the WhatsApp Business app and the API together on the same number at the same time.

What Does This Mean?

  • You keep using the app on your phone as usual.
  • You manage conversations and run automation from Flovoo at the same time.
  • You don’t need to delete the account or change the number.

What Happens to Your Data?

With WhatsApp Business API Only

  • You can’t use the WhatsApp Business app with the same number.
  • Your chat history isn’t moved from the app to Flovoo.
  • If you delete the account from the app during setup, the conversations on it may be deleted.
  • All your new data is in Flovoo only after connecting.

With Coexistence

  • The WhatsApp Business app keeps working normally.
  • Contacts and the last 6 months of conversations can be synced to Flovoo.
  • Old conversations stay available on the app, with no effect on how you use it today.
Comparison titled "API-only setup or Coexistence for your WhatsApp Business?" in two columns: API-only does not transfer existing chat history and stops the WhatsApp Business app working on the same number, while Coexistence syncs contacts and up to six months of conversations and keeps the app active.

When to Use Each Option?

Use WhatsApp Business API If:

  • You need full automation and central management.
  • Your team works entirely from Flovoo.
  • You don’t need to use the app on your phone.

Use Coexistence If:

  • You already use the WhatsApp Business app.
  • You want to move to the API gradually, without changing how you work today.
  • You need to combine manual replies from the app with automation from Flovoo.

After choosing the right setup, follow the connection steps in Connect the WhatsApp Business App (Coexistence), the setup we recommend, or Connect a New Number to WhatsApp Business API.


Can I use the WhatsApp Business app after connecting my number to the API only?
No. In an API-only setup, the number runs through Flovoo and can’t be used on the app.
Are my old conversations moved to Flovoo?
With Coexistence, contacts and the last 6 months of conversations can be synced. With an API-only setup, your chat history isn’t moved.
Do I need to delete my WhatsApp Business account to use Coexistence?
No. Coexistence lets you connect the same number without deleting the account or changing the number.
Can I make WhatsApp calls from Flovoo?
No. With Coexistence, calls are made from the app only, and with an API-only setup, calls aren’t available.
Which option is better if I already use the app?
Coexistence is the better fit, because it lets you move to the API gradually without changing how you work today.
