Understanding Browser CORS
When testing APIs from a web browser, endpoints must permit Cross-Origin requests via standard Access-Control-Allow-Origin headers. If you encounter a network failure or blocked request, ensure your backend server includes CORS headers for development, or use our quick sample endpoints to test your workflow.
