No more switching to Postman or maintaining .http files. Green run buttons appear next to every API operation in your YAML editor — click, review, send.
APICue brings Postman-class API testing into your IntelliJ IDEA — tightly coupled with your OpenAPI specifications.
Green ▶ buttons appear next to every get:, post:, put:, delete:, and patch: operation. Click to open the test panel instantly.

Reads securitySchemes and security from your spec, auto-generates Bearer JWT, Basic Auth, and API Key headers. No manual setup.
Switch between multiple servers per YAML file. Last-selected URL is remembered per-file across IDE restarts.
Query params, headers, and body auto-filled from example, default, and schema property values following a well-defined priority hierarchy.
Save working request/response payloads back to the YAML as OpenAPI examples. Load them later for reproducible testing and regression checks.
Manage JWT, API Keys per environment with a built-in Token Manager. Tokens stored securely using your IDE's password-safe mechanism.
Export your OpenAPI spec as Markdown or HTML documentation — directly from the tool window toolbar or right-click YAML file. Includes search/filter dialog, configurable content sections, and table-of-contents.
Fully resolves $ref across YAML files (e.g. $ref: 'model.yml#/…') with caching and circular-reference detection.
Supports EN, 中文, 日本語, 한국어, Español, Português, Deutsch, Français, Русский, Tiếng Việt, Türkçe. Automatically matches your IDE's language setting. Perfect for global teams.

JCheckBox endpoint list with line-number navigation, export, and auto-load when a YAML file opens.
