HTTP Client is JetBrains' built-in tool for creating, editing, and executing HTTP requests directly from the IDE. Requests are stored in .http and .rest files alongside source code, with code highlighting, completion for hosts and methods, code folding, inline documentation, and live templates accelerating composition. The client supports HTTP/1.1 and HTTP/2 requests, gRPC unary and server-streaming calls, WebSocket connections, GraphQL operations, server-sent events, and imports from cURL and Postman collections. Environment files define reusable variables across global, request, and secured scopes; the cookie jar, request history, run/debug configurations, and Services tool window response viewer round out a workflow tightly integrated with the IntelliJ-based IDE family.
