API-first web development
Agreeing the API first lets your website, app and partner systems draw on the same data.
Background
The approach pays off once several channels need the same data: a website, app, customer portal or partner systems. The starting point is an interface contract covering endpoints, data structures and error cases. Because it is fixed, front-end and back-end teams work in parallel.
Benefits for decision-makers
Faster time to market through parallel development
Lower risk in a redesign, because front ends can be swapped out
No duplicate maintenance of the same data
New channels without rebuilding the back end
Technology
We describe interfaces in OpenAPI and usually implement them as a REST API in Laravel, or with GraphQL where needed. Authentication uses OAuth 2.0 or Laravel Sanctum. Documentation and test cases are generated automatically from the OpenAPI description.
Approach
Clarify use cases and data flows
Draft the API contract in OpenAPI and agree it
Provide a mock server so front-end work can start straight away
Implement the API with automated contract tests
Security and stability
Every request is authenticated and validated, and rate limiting protects against overload. Contract changes are released as a new version, so existing clients keep working. Partners get a sandbox with test data.
