Come utilizzare API Tester
Select method and URL
Choose an HTTP method (GET, POST, PUT, etc.) from the dropdown menu and enter the URL of the API endpoint you want to test.
Configure Header and Body
Add custom headers in the format "Key: Value" (one per line). For POST/PUT/PATCH requests, insert your JSON body into the dedicated textarea.
Send and Analyze
Send Request and Analyze Response: code state, response time, headers, and body. You can copy the response to notes.
Verify and iterate
Modify parameters and resend the request to iterate quickly on testing. Use the "Headers" tab to inspect response headers from the server.
Suggerimenti
- Add "Content-Type: application/json" to headers when sending JSON data in the body.
- Use the HEAD method to quickly check if an endpoint exists without downloading the full body.
- Code 401 indicates authentication issues, code 403 indicates authorization issues.
Domande frequenti
Does this tool support authenticated requests?
Sì, puoi aggiungere header di autenticazione come "Authorization: Bearer <token>" o "X-API-Key: <key>" nella sezione Headers.
Are requests executed by the browser or the server?
Requests are proxied through our backend to allow testing of APIs that would otherwise block requests due to CORS issues.
What is the maximum request timeout?
Timeout is set to 30 seconds on the backend. If no response arrives within this time limit, the request will be terminated.
Can I send form data or files?
Currently the tool supports JSON bodies and simple text. For multipart/form-data, dedicated tools like Postman or curl are required.
