After migrating or deleting a business solutions provider (BSP) number, it is possible that your WhatsApp Business account will continue to be linked to a "phantom partner".
This prevents a new BSP from taking control of the telephone number or which the company manages directly. Now we will proceed with a downgrade and re-onboarding to eliminate these metadata.
Preparation and backup
Before starting, be aware that this process will temporarily disconnect the phone number.
Inactivity notice: The number will be out of service for messages during the process.
Backup: Make sure there are no pending messages on the webhook from the previous provider.
Note: You must have physical or remote access to the SIM card or to the SMS/voice reception system of the query number.
Delete the connection using the Business Manager
Even if the WhatsApp service provider (BSP) indicates that it has been deleted, check manually:
Access the Business Manager.
Go to Accounts > WhatsApp Accounts.
Select the account and check in Members. If the number still appears in the list of the previous partner, request complete deletion or try to revoke access to the asset.
Reset via WhatsApp (Consumer)
When linking a telephone number, you use API or coexistence, a mobile application, the Meta system changes the type of account, which breaks the relationship with the commercial partner.
Download the WhatsApp Messenger application on your mobile device (Android or iOS) and keep the WhatsApp Business application installed.
Enter the phone number in the WhatsApp Messenger application.
Confirm and follow the migration process.
Once the number is active on the phone, the connection with the previous "ghost partner" is automatically invalidated.
Re-Onboarding with a New Partner
Now that the number is "clean", you can link it to the new BSP (Darwin App) using the API and through Coexistence (link the phone number to the WhatsApp Business application).
