Switching from WhatsApp Business API to WhatsApp Business App

If your customer wants to stop using the WhatsApp Business API and switch to the WhatsApp Business App, follow these steps.

⚠️

This is not a direct downgrade. The two systems (API and App) are separate and not interchangeable.

🔁 Migration Overview

• The phone number used with the API must be released from Meta before it can be used with the Business App.
• Once the number is deleted from Meta’s system:
  • API access is revoked immediately.
  • The number becomes eligible for reuse after up to 30 days.

✅ Step-by-Step Guide

1. Remove the Phone Number from Meta

• Go to Facebook Business Manager → WhatsApp Manager.
• Navigate to the Phone Numbers section.
• Select the number and choose Delete or Release.
  • If the option is not visible, contact Meta Support to request the release.

🛑

API access will stop working immediately after deletion. Plan accordingly.

2. Wait for Meta to Fully Release the Number

• Meta may take up to 30 days to fully release the number for reuse.
• During this time:
  • You cannot register the number on the WhatsApp Business App.
  • You cannot use the API — it's already disabled.

3. Register the Number on WhatsApp Business App

• After confirmation that the number is fully released:
  • Install the WhatsApp Business App (iOS or Android).
  • Register using the same phone number.

⚠️ Important Notes

• Chat history, templates, and API integrations will be lost.
• The customer will need to manage chats manually via the mobile app.
• If switching urgently, consider using a different phone number for the Business App.
