Getting Started
Send your first request#
Install the desktop app or open the browser version if you want to try it instantly.
Enter a URL, choose an HTTP method, and send the request to inspect the response right away.
Drag and drop an OpenAPI file or import from a URL to generate a complete collection with requests, authentication, and documentation.
When your OpenAPI document changes on disk, API Client can watch for updates and keep requests and collections aligned.
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.
