Credential isolation
Provider API keys and webhook tokens belong in protected server environment variables, never browser-visible code.
Security
Designed as a DDAI-owned gateway for sensitive voice workflows.
Customer-facing pages and dashboards stay separate from provider credentials, webhook secrets, and administrative controls.
Controls
Security principles built into the operating model.
Authenticated webhooks
Provider callbacks use their own route and validation method, including bearer tokens or provider signatures.
Access control
Customer dashboard and administrative functions require authentication and tenant-aware authorization.
Audit records
Important provisioning and account actions should be logged with structured records and secret redaction.
Network boundaries
Public traffic should terminate at the reverse proxy, while API services, databases, and caches stay on private networks.
Operational approvals
Live phone purchases, outbound calling, and sensitive provider changes should require explicit administrative confirmation.
Trust detail
Provider systems stay behind the DDAI gateway.
The public site describes the product. The application and API are responsible for authentication, authorization, webhook checks, tenant separation, and provider orchestration.
