NexisGate - Gateway

The secure channel gateway for business applications.

Gateway handles message transport, identity/session boundaries, provider onboarding, policy gates, outbox, delivery evidence, audit and diagnostics while business applications focus on their own workflows.

Gateway architecture diagram

Core gateway capabilities

Own transport. Protect business applications.

The Gateway pattern separates provider connectivity from application-specific business logic.

MO / MT ownership

Receive inbound messages, normalize events, route to applications, accept outbound contracts, and send through configured channel providers.

Provider governance

Control WhatsApp accounts, templates, Telegram bots, future channels, token references, delivery evidence, and platform policy gates.

Audit-first operations

Keep correlation IDs, evidence, retries, failure reasons, and administrative action logs for production operators.

Application contract

Applications return contracts. Gateway sends.

Business apps should not send directly through external channel providers. They receive normalized inbound events and return validated outbound contracts to the Gateway.

Gateway inbound event → Application handler
Application outbound contract → Gateway outbox
Gateway provider send → Delivery evidence
