WhatsApp Business Management API - Owned WhatsApp Business Accounts | Developer Documentation

Confirm who controls the intended business assets

Use this check before connecting a business number, involving an agency or changing an existing provider. Being able to see an account does not establish who owns the business assets or who is authorized to change their connection.

Agree on the business and the responsible person

• Identify the business that should use the WhatsApp number and the person responsible for its Meta business portfolio.
• Check the selected portfolio and WhatsApp account with that person. Use the account guide and label available references using the identifier checklist.
• Where ownership information is visible, compare it with the intended business. If an agency or another portfolio is involved, ask the responsible administrator to explain the arrangement.
• Record the currently connected tool/provider and who may approve a change. Access granted to a person or partner does not itself prove an ownership transfer.

Prepare access without replacing an existing account

Use the business-access guide to check the Facebook account and the relevant WhatsApp asset. An employee's Facebook login, the company's account and the ChatArchitect API credential pair are different parts of the setup.

If the number is already in use, follow the change-planning checklist before withdrawing access, deleting an account or starting a move. The supported transfer route, effect on the existing service and recovery method need confirmation for that case.

Confirm the selection in the connection flow

Use the supplied number connection. Compare the actual portfolio, account and number shown in the flow with the agreed record before authorizing access. Stop at a mismatch and clarify it with the responsible administrator or ChatArchitect support.

The Meta owned-account API is a separate developer reference. A regular customer does not need to call that endpoint to make this control check, and this article does not establish a self-service account-ownership transfer.
