Question

I'm trying to create a card with my webhook service. my website is in php but I don't know how to respond to api.ai in a way to display my result in card format on client's phone. I ask my question with more detail in here.

Considering, you know receiving and checking action from Api.ai request in php

For responding with the card, you can use this:

$request== file_get_contents("php://input");
$messages=[];
// Building Card
 array_push($messages, array(
    "type"=> "basic_card",
    "platform"=> "google",
    "title"=> "Card title",
    "subtitle"=> "card subtitle",
    "image"=>[
      "url"=>'http://image-url',
      "accessibility_text"=>'image-alt'
      ],
      "formattedText"=> 'Text for card',
      "buttons"=> [
        [
          "title"=> "Button title",
          "openUrlAction"=> [
            "url"=> "http://url redirect for button"
            ]
          ]
        ]
      )
   );
  // Adding simple response (mandatory)
  array_push($messages, array(
     "type"=> "simple_response",
     "platform"=> "google",
     "textToSpeech"=> "Here is speech and additional msg for card"
    )
  );
  $response=array(
          "source" => $request["result"]["source"],
          "speech" => "Speech for response",
          "messages" => $messages,
          "contextOut" => array()
      );
 json_encode($response);

Make sure you don't push more than one card and have 'simple response' with it.
