Route::post('/save-json', 'JsonController@saveJson');

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\JsonData;

class JsonController extends Controller
{
    public function saveJson(Request $request)
    {
        $jsonData = new JsonData;
        $jsonData->data = $request->json()->all();
        $jsonData->save();

        return response()->json(['message' => 'JSON data saved successfully']);
    }
}

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class JsonData extends Model
{
    protected $table = 'json_data';
    protected $fillable = ['data'];
}

php artisan make:migration create_json_data_table --create=json_data

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateJsonDataTable extends Migration
{
    public function up()
    {
        Schema::create('json_data', function (Blueprint $table) {
            $table->id();
            $table->json('data');
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('json_data');
    }
}

php artisan migrate
