Frequently Asked Questions
What HTTP methods are supported?
We support GET, POST, PUT, DELETE, PATCH, HEAD, and OPTIONS methods. This covers all common REST API operations.
Why do I get CORS errors?
CORS (Cross-Origin Resource Sharing) is a browser security feature. If an API doesn't allow requests from your domain, you'll see CORS errors. This is normal and expected for security reasons.
Can I test local APIs?
Yes, as long as your local server is running and allows browser requests. You may encounter CORS issues with local development servers.
How do I add authentication?
Use the Auth tab to add Bearer tokens, or add custom headers (Authorization, X-API-Key, etc.) in the Headers tab.
Is my data secure?
Yes! All requests are sent directly from your browser to the API endpoint. We never store or see your data or API keys. Use HTTPS endpoints for extra security.
