About API Playground
Free API
and webhook
testing.
API Playground is a free, browser-based API and webhook testing tool for developers, builders, automation teams, and students. It helps users send HTTP requests, test webhook endpoints, inspect JSON responses, and try API templates without installing software or creating an account.
Mission
Make API testing fast, accessible, and friction-free.
APIs power modern software, automations, AI products, internal tools, and customer workflows. But testing a simple endpoint can still feel heavier than it should.
API Playground was built for the moments when you want to paste a URL, add a header, send a request, and understand the response immediately. No install. No account wall. No heavyweight setup before the work can begin.
What it does
A practical browser workspace for API requests and webhook debugging.
02
Add headers, query parameters, authentication, and JSON request bodies.
03
Test webhooks for Make, Zapier, n8n, custom apps, and automation workflows.
04
Inspect status codes, response headers, and formatted JSON responses.
05
Replay requests from history and manage repeat testing flows.
06
Use pre-built API templates for AI chat, image, video, audio, and automation APIs.
