API-Driven Web Applications
New web front ends built on top of existing APIs and back-end platforms, such as ERP, CRM, commerce engines or headless services, delivering better experiences without replacing the systems of record.
Capability overview
What api-driven web applications involves
Core business systems often contain the right data and rules but offer clumsy screens that are difficult for customers, partners or occasional users. Replacing the whole system is expensive and risky. An API-driven web application builds a focused, modern interface on top of existing APIs, leaving the system of record in place.
Examples include simplified ordering screens over SAP or Dynamics, mobile-friendly field service interfaces over ServiceNow, custom quote builders over Salesforce data, and branded experiences over headless commerce or content platforms. A backend-for-frontend layer can combine data from several APIs, enforce security and cache information for performance.
When existing systems lack suitable APIs, we can first create an integration layer, then build the new front end on top of it.
What is included
Architecture and features
API assessment
Available endpoints, authentication, rate limits, data models and gaps in existing systems reviewed.
Backend-for-frontend layer
A lightweight service that aggregates APIs, shapes responses for screens and protects core systems from excess traffic.
Focused user experience
Interfaces designed around specific user tasks rather than exposing every function of the underlying system.
Caching and resilience
Caching, retries, timeouts and graceful error handling for slow or unavailable back-end systems.
Security and identity
Single sign-on, token handling, permission checks and audit logging across API calls.
How we work
How we deliver api-driven web applications
User task analysis
The tasks users struggle to complete in current systems identified and prioritised.
API gap review
Existing APIs mapped to required tasks and missing capabilities documented.
Architecture design
Frontend, BFF, caching and security patterns designed with system owners.
Iterative build
Screens and API orchestration delivered in releases with real system data.
Load and failure testing
API limits, latency and back-end outages tested before launch.

Ask a questionYes. Many organisations build focused web applications over ERP APIs for specific users, such as dealers, field staff or approvers, while finance and operations continue using the full ERP.
The design uses caching, rate limiting and efficient API calls to protect core systems. Load testing confirms the effect before launch.
An integration layer can use database views, middleware, events or files to create APIs. The new front end then depends on that stable interface.
Based on user journeys, APIs involved, backend-for-frontend logic, integration gaps and security requirements.
