$output = curl_exec($ch); // This is API Response
        curl_close($ch);
        $result = json_decode($output,true);

        return view("bca.cekmutasi", [
            "result" => $result
            ]);

this my view

@if (isset($result))
@foreach ($result as $key => $value)
<div class="col-xs-6">
  <ul class="list-unstyled" style="line-height: 2">
  <li><span class="fa fa-circle text-success"></span> TransactionDate : <b></b></li>
  </ul>
</div>
@endforeach
@endif
