Hi…

I am facing trouble while sending Facebook’s generic template payload from custom action. Please any working example suggest or explain in detail.

Which one is suitable for it ?

    dispatcher.utter_custom_json()
    dispatcher.utter_custom_message()
    dispatcher.utter_elements()
    dispatcher.utter_button_message()
    dispatcher.utter_template()
   x dispatcher.utter_image_url()
   x dispatcher.utter_attachment()

Template payload link : Generic Template - Messenger Platform - Documentation - Facebook for Developers

"payload": {
  "template_type":"generic",
  "elements":[
     {
      "title":"<TITLE_TEXT>",
      "image_url":"<IMAGE_URL_TO_DISPLAY>",
      "subtitle":"<SUBTITLE_TEXT>",
      "default_action": {
        "type": "web_url",
        "url": "<DEFAULT_URL_TO_OPEN>",
        "messenger_extensions": <TRUE | FALSE>,
        "webview_height_ratio": "<COMPACT | TALL | FULL>"
      },
      "buttons":[<BUTTON_OBJECT>, ...]      
    },
    ...
  ]
}

Thank You

I just figured out, after some inspecting and comparison with quick_replies

Answer is check below… If any have issue like this problems…

Facebook’s example demo for generic template :

curl -X POST -H "Content-Type: application/json" -d '{
  "recipient":{
    "id":"<PSID>"
  },
  "message":{
    "attachment":{
      "type":"template",
      "payload":{
        "template_type":"generic",
        "elements":[
           {
            "title":"Welcome!",
            "image_url":"https://petersfancybrownhats.com/company_image.png",
            "subtitle":"We have the right hat for everyone.",
            "default_action": {
              "type": "web_url",
              "url": "https://petersfancybrownhats.com/view?item=103",
              "webview_height_ratio": "tall",
            },
            "buttons":[
              {
                "type":"web_url",
                "url":"https://petersfancybrownhats.com",
                "title":"View Website"
              },{
                "type":"postback",
                "title":"Start Chatting",
                "payload":"DEVELOPER_DEFINED_PAYLOAD"
              }              
            ]      
          }
        ]
      }
    }
  }
}' "https://graph.facebook.com/v2.6/me/messages?access_token=<PAGE_ACCESS_TOKEN>"



And this way, You can use above example in our custom action file :

       gt = {
            "attachment": {
                "type": "template",
                "payload": {
                    "template_type": "generic",
                    "elements": [
                        {
                            "title": "Welcome! 1",
                            "image_url": "https://picsum.photos/200",
                            "subtitle": "We have the right hat for everyone.",
                            "default_action": {
                                "type": "web_url",
                                "url": "https://tithal.life",
                                "webview_height_ratio": "tall",
                            },
                            "buttons": [
                                {
                                    "type": "web_url",
                                    "url": "https://tithal.life",
                                    "title": "View Website"
                                },
                                {
                                    "type": "postback",
                                    "title": "Start Chatting",
                                    "payload": "DEVELOPER_DEFINED_PAYLOAD"
                                }
                            ]
                        },
                        {
                            "title": "Welcome! 2",
                            "image_url": "https://picsum.photos/200",
                            "subtitle": "We have the right hat for everyone.",
                            "default_action": {
                                "type": "web_url",
                                "url": "https://tithal.life",
                                "webview_height_ratio": "tall",
                            },
                            "buttons": [
                                {
                                    "type": "web_url",
                                    "url": "https://tithal.life",
                                    "title": "View Website"
                                },
                                {
                                    "type": "postback",
                                    "title": "Start Chatting",
                                    "payload": "DEVELOPER_DEFINED_PAYLOAD"
                                }
                            ]
                        }
                    ]
                }
            }
        }
        dispatcher.utter_custom_json(gt)

Compare both code and anyone can figure it out. Thanks :+1: :tada::tada:
