APIs & API Management

API-led connectivity, security and partner onboarding

Expose what your business does as governed, reusable APIs, so partners and channels can be onboarded in days, not weeks, without ever exposing the systems behind them. nVisionIT publishes capability through Azure API Management: the secure front door, policy enforcement point and developer catalogue for every back-end you run.

The opportunity

Turn your systems into a product partners can plug into

An API is a promise: a stable, secure contract to a capability. Manage those promises well and integration stops being a bespoke project every time, and becomes self-service.

One secure front door

Every back-end, SaaS, packaged apps, partner platforms, your own services, is fronted and protected by a single governed gateway.

A catalogue & developer portal

A discoverable catalogue of APIs and a self-service portal turn partner and internal onboarding from a support ticket into a login.

Centralised control

Security, versioning and traffic management live in one place, so policy changes don’t mean touching back-end code.

6 weeks → <10 days

On a provincial-government integration fabric, reusable APIs and an event-driven architecture cut partner onboarding from around six weeks to under ten days, with more reliable data flows and a foundation built to scale.

How it works

API-led connectivity

APIs are layered so that change is contained and assets are reused. A change deep in a system of record is absorbed by its System API. The layers above, and every consumer, are unaffected.

Experience APIs

Channel-specific APIs shaped for each consumer, web, mobile, partner, decoupling the channel from the core.

Process APIs

Orchestrate business processes across systems with Logic Apps workflows, rules, transformation and aggregation.

System APIs

Expose systems of record behind stable contracts: ERP, CRM, core banking, legacy and databases.

Each API is built once, governed centrally and reused across every solution and accelerator, so the second project is faster than the first, and the tenth faster still.

Secured by design

Zero Trust at every layer

API Management sits in front of your back-ends, and security is enforced at the gateway before a request ever reaches a system. We standardise on OAuth 2.0 for authorization, paired with OpenID Connect for user authentication and single sign-on, with mutual TLS available for the strongest client authentication.

  • Managed identities first: for clients on Azure in the same Entra ID tenant, managed identities remove secret management entirely: highest security, least overhead.
  • Certificates over secrets: where a credential is needed, certificates are preferred, because the private key never travels the network.
  • Validate tokens at the gateway: JWTs are checked (issuer, audience, scopes) before a request reaches a back-end.
  • Protect tokens in transit: bearer tokens are always transmitted and stored securely to prevent interception.
Governance, networking & operations

Enterprise-grade by configuration

Stable contracts, evolving code

Versioning and revisions keep contracts stable while implementations change underneath them.

Protected back-ends

Rate limiting and quotas shield systems from overload and enable tiered partner access.

Private networking

Multi-region, highly available deployments with private endpoints, APIs reachable only over private traffic in hub-and-spoke, firewall-controlled architectures.

Policies, not rewrites

Transform, route and enrich requests through policy, including routing an HTTP request straight to Service Bus for asynchronous processing, with no extra components.

Design-first governance

APIs and events are contracts

REST APIs are described with OpenAPI and event-driven interfaces with AsyncAPI, the event-driven equivalent, protocol-agnostic across AMQP, Kafka, MQTT, WebSockets and HTTP.

  • Linted in the pipeline: definitions are checked (for example with Spectral) against an organisation-wide style guide, so every interface is consistent, secure and discoverable before it ships.
  • Catalogued for reuse: a central API and event catalogue supports discovery and reuse across teams.
  • Contract-tested: tests verify that implementations match their specs, and breaking changes route through an approval workflow.
