How do I convert a cURL command to Go?

Paste the full command, starting with curl, into the Input cURL Command box. The Go code appears below as you type, and Copy Go Code puts it on your clipboard.

Which cURL flags does the converter understand?

It reads -X, -H, -d and the other --data variants, --json, -u, -A, -b, -e, and --url. Flags such as -F, -G, -k, and -L are ignored, so add multipart bodies, query building, TLS settings, or redirect rules to the Go code yourself.

Does the Go code set a Content-Type for -d data?

No, not unless your command includes a Content-Type header. curl adds application/x-www-form-urlencoded for -d on its own, but Go does not, so add req.Header.Set("Content-Type", "application/x-www-form-urlencoded") when the server needs it. The --json flag does set Content-Type and Accept to application/json.

How is basic auth from -u converted?

The user:password value is Base64-encoded and written as an Authorization: Basic header. That puts the credential in your source file, so switch to req.SetBasicAuth with values from environment variables before you commit the code.

Can I use the generated Go code in production?

Use it as a starting point, not as finished code. It calls panic on every error, uses an http.Client with no timeout, and prints the response body to stdout. Return errors, set a Timeout, and run gofmt before shipping.

	"io"
	"net/http"
	"strings"
)
func main() {
	url := "https://api.stripe.com/v1/charges"

	req, err := http.NewRequest("POST", url, payload)
	if err != nil { panic(err) }
	req.Header.Set("Authorization", "Basic c2tfdGVzdF9rZXk6")
	client := &http.Client{}
	res, err := client.Do(req)
	if err != nil { panic(err) }
	defer res.Body.Close()
	body, err := io.ReadAll(res.Body)
	if err != nil { panic(err) }
	fmt.Println(string(body))
}

About cURL to Go HTTP Client Converter

The cURL to Go Converter turns a cURL command into a complete Go program that sends the same request with net/http. Paste a command copied from API docs or browser DevTools and the tool reads the URL, method, -H headers, -u basic auth, cookies, user agent, and -d or --json body, then writes http.NewRequest, req.Header.Set calls, and io.ReadAll for the response. The output is a starting point: errors use panic, and form uploads with -F are not converted. Parsing happens in your browser.
