Test any REST API from your browser or phone
Build requests, save them in collections, reuse variables and add assertions that tell you instantly whether an API behaves correctly.
Collections & variables
Organise requests and reuse {{base_url}} or tokens across them. Values are stored encrypted.
Assertions
Check status codes, response time, headers and JSON values with pass/fail results.
Works on mobile
Use the same tester from the API24x7 mobile app when you are away from your desk.
Safe by design
Requests to private networks and internal addresses are blocked to protect everyone.
How it works
-
1
Open the tester and enter a URL.
-
2
Add headers, a body and assertions.
-
3
Save the request to a collection to reuse it.
