SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill tackles the complexity of modernizing legacy API architectures, enabling enterprises to transition from outdated SOAP/XML services to REST or GraphQL, and decompose monolithic services into efficient microservices.

Core Features & Use Cases

Migration Vectors: Supports SOAP/XML to REST, REST to GraphQL, and monolith to microservices.
Full Lifecycle Management: Covers API discovery, contract analysis, implementation, testing, and traffic cutover.
Use Case: An enterprise with hundreds of SOAP/XML services needs to expose its core data through modern APIs. This Skill can systematically convert these services to RESTful endpoints, improving developer velocity and integration capabilities.

Quick Start

Use the api-modernization skill to convert the provided WSDL file 'notification.wsdl' to a RESTful API.

FAQPage Schema

How do I migrate SOAP to REST APIs?▼

Migrating SOAP to REST APIs involves analyzing WSDL contracts and systematically converting XML payloads to RESTful endpoints. This process automates API discovery, generates OpenAPI specifications, and handles implementation through to traffic cutover for legacy services.

What is the best way to decompose a monolithic service into microservices?▼

Decomposing a monolithic service into microservices requires understanding the existing codebase and API contracts. The process leverages DeepWiki for codebase analysis, extracts service boundaries, and generates independent microservice implementations with structured traffic cutover.

Can I convert REST APIs to GraphQL automatically?▼

Converting REST APIs to GraphQL automatically is supported by analyzing existing REST contracts and generating GraphQL schemas. The migration covers full lifecycle management including implementation, testing, and routing traffic from REST endpoints to the new GraphQL layer.

Does API modernization work with existing WSDL files?▼

API modernization works directly with existing WSDL files to convert SOAP/XML services to RESTful APIs. It analyzes the provided WSDL contracts, generates corresponding OpenAPI specifications, and implements the new REST endpoints while maintaining full lifecycle testing.

When do I need to transition from REST to GraphQL?▼

Transitioning from REST to GraphQL is needed when improving developer velocity and integration capabilities for complex data fetching. This modernization vector converts existing REST contracts into GraphQL schemas, optimizing API architecture through automated implementation and traffic cutover.

What does full lifecycle API migration include?▼

Full lifecycle API migration includes API discovery, contract analysis, implementation, testing, and traffic cutover. It automates converting legacy SOAP/XML or REST architectures by generating OpenAPI or GraphQL specifications and leveraging DeepWiki for codebase understanding.
