Getting Started

Send your first request with API Client in minutes. Download the app for macOS, Windows, or Linux, or jump straight into the browser version.

Send your first request

Open API Client

Install the desktop app or open the browser version if you want to try it instantly.

Send your first request

Enter a URL, choose an HTTP method, and send the request to inspect the response right away.

Import your OpenAPI document

Drag and drop an OpenAPI file or import from a URL to generate a complete collection with requests, authentication, and documentation.

Keep everything in sync

When your OpenAPI document changes on disk, API Client can watch for updates and keep requests and collections aligned.

Add response tests

Use post-response scripts to validate responses and automate checks while you explore your API.

Import and sync OpenAPI

Bring an OpenAPI document into API Client to generate requests, authentication, and collection structure from the API your team already maintains.

Use Import to bring in local files or URLs, then use environments and dynamic variables to move between local, staging, and production without duplicating requests.

Test and automate responses

API Client supports request scripts and response tests, so you can automate setup, assertions, and debugging as you work through an API.

Start with Scripts for pre-request and post-response workflows, then use Testing to validate status codes, headers, and response bodies.
