Changelog

Async POST /v1/numbers/verifications + GET/status ( scope numbers:verify). Sandbox settles without live providers; production auto-dispatches the shared verification engine. Docs at /docs/numbers.

Public documentation redesign: sidebar IA, endpoint samples, service guides (airtime, data, ECG, voice/AFA), errors, and sandbox/production depth.

Applications, sandbox/production isolation, /v1/transactions, /v1/products, portal /developers, Ops /office/developers, open-to-all platform switch, webhook HMAC headers.

Initial prepaid Partner HTTP API. /v1/purchases remains as a legacy alias for create/get transaction.
