WebApiClient is a declarative REST API client library for .NET where developers define HTTP clients by declaring C# interfaces. It supports JSON, XML, and form serialization, AOP features like interceptors, retries, and caching, OAuth2 extensions, and OpenAPI-to-code generation, claiming 2x better performance than Refit.

Use cases

• generate typed HTTP clients from OpenAPI/Swagger documents
• declare REST API clients as C# interfaces instead of writing HttpClient boilerplate
• call REST APIs with JSON, XML, or form serialization in .NET
• handle OAuth2 token management for API authentication
• add retries, logging, and caching to HTTP requests via interceptors
• publish trimmed/AOT .NET apps that consume web APIs

When to choose

• you're on .NET and want a fast declarative HTTP client library
• you want to auto-generate client code from OpenAPI documents
• you need built-in OAuth2/token management extensions
• you need AOT/trimming support for your API clients

When to avoid

• you're not on the .NET platform
• you prefer Refit's ecosystem or community size
• you need a low-level HTTP client with full manual control
• you need a server-side framework rather than a client library
