/v1/gstin - Header authentication via
X-API-Key
Go example
Go
package main
import (
"fmt"
"net/http"
"io"
)
func main() {
req, _ := http.NewRequest("GET", "https://gstchk.apiseeker.com/v1/gstin/29ABCDE1234F1Z5", nil)
req.Header.Set("X-API-Key", "YOUR_API_KEY")
res, err := http.DefaultClient.Do(req)
if err != nil { panic(err) }
defer res.Body.Close()
body, _ := io.ReadAll(res.Body)
fmt.Println(string(body))
