This error appears when you try to connect a WhatsApp phone number to a new platform while it is still linked to another WhatsApp Business API provider. To resolve the issue, disconnect the existing partner before starting the new onboarding process.

Error Message

Why Does This Error Occur?

This error may occur when:

1. The phone number is already connected to another Business Solution Provider (BSP).

2. A previous integration was not properly disconnected.

3. The number is still linked to a test or demo account.

How to Fix This Error

Step 1: Disconnect from the Existing Partner

2. Go to Settings then Account.

3. Look for Business Platform or Linked Devices.

4. Find the currently connected platform or partner.

5. Tap Disconnect.

6. Confirm the disconnection.

Step 2: Wait for the Changes to Take Effect

After disconnecting the existing platform, wait approximately 5–10 minutes for the connection status to update across WhatsApp's systems.
