Direct HTTP: Go

No Facta library required

Call the public Supabase function URL directly. Keep API keys and signing keys on your server.

Prerequisite

Go net/http

Example

package main

import (
	"bytes"
	"fmt"
	"net/http"
	"os"
	"strings"
)

func main() {
	body := []byte(`{"tipoDte":"01","items":[{"descripcion":"Servicio","cantidad":1,"precioUni":10.0}]}`)
	req, _ := http.NewRequest(http.MethodPost, strings.TrimRight(os.Getenv("FACTA_API_BASE_URL"), "/")+"/v1/dte", bytes.NewReader(body))
	req.Header.Set("Content-Type", "application/json")
	req.Header.Set("X-Facta-Key", os.Getenv("FACTA_API_KEY"))
	req.Header.Set("X-Facta-Sign-Key", os.Getenv("FACTA_SIGN_KEY"))
	req.Header.Set("Idempotency-Key", "order-123")
	response, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	defer response.Body.Close()
	fmt.Println(response.Status)
}
