How to get custom payload response from dialogflow to API in PHP

Question

Getting only text response for the intent but the custom payload response is missing in api response.

Dialogflow raw response is Image

{
"allRequiredParamsPresent": true,
"fulfillmentText": "Thanks Dhruva, are you ?",
"fulfillmentMessages": [
  {
    "text": {
      "text": [
        "Thanks Dhruva, are you ?"
      ]
    }
  },
  {
    "payload": {
      "richContent": [
        [
          {
            "type": "chips",
            "options": [
              {
                "text": "permanent employee"
              },
              {
                "text": "probation employee"
              }
            ]
          }
        ]
      ]
    }
  }
]
}

Api receiving only text not custom payload Image

Took a reference from this post but was unable to fix either, any help or point to the right direction will be appreciated thanks.

Answer 1

This is what I did to get the custom payload in a php associative array

        $textInput = new TextInput();
        $textInput->setText($request->query("message","message that has custom payload response"));
        $textInput->setLanguageCode("en-US");

        //Putting it in query input
        $queryInput = new QueryInput();
        $queryInput->setText($textInput);
        $response = $sessionClient->detectIntent($session, $queryInput);
        $queryResult = $response->getQueryResult();

        //Beginning of solution
        $fulfillmentMessages = $queryResult->getFulfillmentMessages();
        $customPayloads = []; //The result array

        foreach ($fulfillmentMessages as $fulfillmentMessage) {
            /* @var $fulfillmentMessage Message*/
            if($fulfillmentMessage->hasPayload()) {
                $customPayloads[] = json_decode($fulfillmentMessage->getPayload()
                    ->serializeToJsonString(),1);
            }
        }
