To perform read-only API queries, implement a handler that executes HTTP GET requests using HttpClient from WebApplicationFactory, applying JWT authentication and path or query parameters while storing the response for downstream verification.

Query steps enforce an explicit no-state-change policy by performing HTTP GET requests, whereas command steps allow server mutations. This distinction prevents side effects during integration testing and ensures safe read model delegation.

Authenticate HttpClient requests with JWT in C# SpecFlow tests by adding an Authorization header to your HTTP GET request. The query handler builds the request with this header before sending it to the WebApplicationFactory endpoint.

WebApplicationFactory supports API endpoint testing with path and query parameters by allowing the query handler to construct URLs dynamically. The handler performs HTTP GET requests against these endpoints and stores the response for validation by downstream handlers.

Separating read-only query steps from command steps enforces a no-state-change policy during API testing. This prevents unintended side effects, ensuring HTTP GET requests only retrieve data for read model delegation and response verification.
