FAQ
- What is an API tester?
- A tool that sends HTTP requests to an endpoint and shows the response — status, headers, and body — so you can verify an API behaves as expected.
- How do I test an API?
- Choose a method, paste the URL, add headers or a body if needed, then Send. Check the status code and payload against what you expect.
- Why use Tatum's tester?
- Test any public API without signup, then jump into curated Gateway, Data API, and Rates calls that map 1:1 to production Tatum endpoints.
