SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Frontend-backend API misalignments cause runtime errors and wasted cycles. This skill provides a structured approach to validate contracts, wire the API client, and orchestrate third-party configurations before QA.

Core Features & Use Cases

Contract verification: ensure frontend usage matches the OpenAPI specification and that request/response shapes align.
API client integration: ensure a typed client is wired with proper authentication and error handling.
Third-party setup: configure auth providers, payments, and webhooks as defined by PRD.
E2E data flow verification: validate end-to-end flows from login through protected API calls to UI updates.

Quick Start

Begin by validating the OpenAPI spec against the deployed backend, then wire in the frontend API client and configure third-party services per PRD.

FAQPage Schema

How do I validate frontend-backend API contracts to prevent integration errors?▼

To validate API contracts, check that frontend usage matches the OpenAPI specification and that request and response shapes align. This structured verification prevents runtime misalignment surprises before reaching QA.

What is the best way to wire a typed API client with proper authentication and error handling?▼

Wiring a typed API client involves integrating the frontend client with the backend specification, ensuring proper authentication flows and error handling are configured to support end-to-end data flow.

How do I configure third-party services like auth providers and webhooks for my application?▼

Configuring third-party services requires setting up auth providers, payments, and webhooks as defined by your PRD. This ensures external integrations align with your application requirements before end-to-end testing.

Can I verify end-to-end data flow from login through protected API calls to UI updates?▼

Yes, you can verify end-to-end data flow by validating the complete path from user login through protected API calls to final UI updates. This confirms the frontend-backend integration works as expected.

When do I need OpenAPI validation for frontend-backend integration?▼

OpenAPI validation is needed during frontend-backend integration, client wiring, and third-party configuration from MVP to production. It ensures request and response shapes align to prevent runtime errors and wasted development cycles.
