package main

import (
	"encoding/json"
	"fmt"
	"net/http"
)

type Response struct {
	Status bool `json:"status"`
	Data   []struct {
		FullCode string `json:"full_code"`
		Name     string `json:"name"`
	} `json:"data"`
}

func main() {
	res, err := http.Get("__BASE_URL__/api/locations/provinces")
	if err != nil {
		panic(err)
	}
	defer res.Body.Close()

	var payload Response
	json.NewDecoder(res.Body).Decode(&payload)

	for _, item := range payload.Data {
		fmt.Println(item.FullCode, item.Name)
	}
}

Memerlukan Laravel HTTP Client.

use Illuminate\Support\Facades\Http;

$response = Http::get('__BASE_URL__/api/locations/provinces');
$json = $response->json();

if (! $json['status']) {
    throw new Exception($json['message']);
}

$provinces = $json['data'];

Menggunakan standard library Python.

import json
from urllib.request import urlopen

base_url = '__BASE_URL__'
with urlopen(f'{base_url}/api/locations/provinces', timeout=10) as response:
    payload = json.load(response)

if not payload['status']:
    raise Exception(payload['message'])

provinces = payload['data']
print(provinces[0]['name'])
