FAQ
What are API tools?
API tools help developers work with web APIs. They include request builders, cURL converters, HTTP status code references, and CORS header generators.
Do API tools send actual requests?
The API Request Builder generates request code (cURL, fetch, axios) but doesn't send requests directly. The Webhook Tester does send actual HTTP requests for testing purposes.
