WSDL Converter

About This Tool

The wsdl converter ingests a WSDL document or URL and produces an OpenAPI specification (OpenAPI 3.0 or 2.0) and related artifacts. It targets developers integrating SOAP services into REST clients, API teams modernizing a service catalog, quality assurance engineers validating service contracts, and architects evaluating interface compatibility. The result is a RESTful view of operations, messages, and bindings captured in a machine readable OpenAPI document.
Conceptually, the tool operates in two phases. First, it parses the WSDL, resolves imports, and builds an intermediate model of services, portTypes, operations, messages, and embedded XML schemas. Second, it maps that model to an OpenAPI representation by turning operations into HTTP paths, exchanging SOAP inputs for JSON request bodies, and associating responses with schema definitions and status codes.
Users benefit from automated contract translation, improved client generation, and consistent documentation across a mixed technology stack. Its value lies in preserving service semantics while exposing conventional REST patterns, allowing teams to test, mock, and evolve SOAP endpoints without rewriting server logic. The converter supports multiple bindings, supports generated client scaffolds, and produces example payloads for quick integration.
Core features include WSDL 1.1 and 2.0 parsing, import resolution, binding mapping, type conversion to JSON schemas, and output in OpenAPI YAML or JSON. Use cases include modernization projects, service catalog migration, API testing, and rapid prototyping of SOAP-based services as REST APIs.
