  description: 'Unified REST API for Africa''s Talking communications products: SMS (single, bulk, premium, subscriptions), USSD callbacks, Voice (call, transfer, media upload, queue status), Airtime, Mobile Data, and Payments (mobile C2B checkout, B2C, B2B). Requests authenticate with an `apiKey` header and a `username` parameter. Hosts differ per product: messaging, airtime, and subscriptions live under api.africastalking.com/version1; voice under voice.africastalking.com; mobile data under bundles.africastalking.com; and payments under payments.africastalking.com. Sandbox equivalents insert `.sandbox.` into each host.'
