Dialogflow CX Messenger richContent event call

[Kiran Upadhya]

I have created a simple agent in Dialogflow CX. In the Dialogflow Messenger When I enter the city name then it performs the webhook call and it will send the richContent like below.

```

{

  "fulfillment_response": {

      "messages": [{"payload": {"richContent": [

    [

      {

        "type": "list",

        "title": "Pin1",

        "event": {

          "name": "getpincode",

          "languageCode": "en",

          "parameters": {"pincode1": "123456",}

        }

      },

      {

        "type": "divider"

      },

      {

        "type": "list",

        "title": "Pin2",

        "event": {

          "name": "getpincode",

          "languageCode": "en",

          "parameters": {"pincode1": "456123",}

        }

      }

    ]

  ]}}],

      "merge_behavior": "APPEND"

    },

}

```

Here I have added an event handler named "getpincode".  In the event setup(getpincode) I have called webhook which returns the hospital name.

In the Dialogflow Messenger, it is now showing 2 pin codes option. I want to send the selected(clicked pin code) PIN code via webhook call, how can I do this?

Right now it is showing the pin code, but when I select the PIN code it is not performing a webhook call (i guess event getpincode is not triggered) WHY? (attached image for reference)

Is I'm missing anything.?

Please guide me.

Thank you,

Kiran
