POST failed via Postman API to Laravel migrations database

Question

GET is working, but POST does not. This is because it fails via Postman API to the Laravel migrations database.

function add_user(Request $request)
{
    $user = new user_a;
    csrf_token();
    $user->user_name = $request->user_name;
    $user->password = $request->password;

    $res = $user->save;
    if ($res) {
        return ["operationn" => "Done"];
    } else {
        return ["operation" => "failed_404"];
    }
}

in API file:

Route::post('registeruser',[dynamic_small_controller::class,'add_user']);

Answer 1

You are trying to send the password in integer format so it is not accepting try with giving password also in ""

{
   "user_name":"yahay",
   "password":"8888"
}
