# List WhatsApp Business accounts

> Lists the project's onboarded WhatsApp Business accounts (WABAs), newest first. Each entry returns the internal `accountId` (used to scope template endpoints under `/accounts/:accountId/templates`), Meta's `wabaId`, the `businessName` Meta returned at onboarding (nullable), and `createdAt`. Returns an empty array if the project has none. Requires Authorization: Basic base64(projectId:projectSecret).
