How to show multiple basic card as a response in dialogflow webhook - dialogflow-es

Question

I want to send three basic cards as a response to the user through JSON response via fulfillment in python. So is there any way to do it?
P.S.
Basically, I want to show three buttons to a user for call, mail and call on office, but as Basic card shows only one link, I thought is it possible to show multiple cards which contain buttons!
This is the response that I'm sending.
{
"payload": {
"google": {
"expectUserResponse": "true",
"richResponse": {
"items": [{
"simpleResponse": {
"textToSpeech": "Here is the information of " + user_name
}
},
{
"basicCard": {
"title": name,
"subtitle": subtitle,
"image": {
"url": picture_url,
"accessibilityText": "Picture of " + name
},
"formattedText": msg,
"buttons": [{
"title": "Call " + user_name,
"openUrlAction": {
"url": "tel:+" + contact
if contact is not None
else "",
"androidApp": {
"packageName": "com.android.phone"
},
"versions": []
}
}
if contact is not None
else {
"title": "Send Mail to " + user_name,
"openUrlAction": {
"url": "mailto:" + email,
"androidApp": {
"packageName": "android.intent.extra.EMAIL"
},
"versions": []
}
},
{
"title": "Call on extention",
"openUrlAction": {
"url": "tel:+" + extension
if extension is not None
else "",
"androidApp": {
"packageName": "com.android.phone"
},
"versions": []
}
}
],
"imageDisplayOptions": "WHITE"
}
}
],
"suggestions": [{
"title": "Info of " + manager
if manager is not None
else ""
},
{
"title": "Info of " + hr_manager
if hr_manager is not None
else ""
}
]
}
}
}
}

Answer 1

You can't send multiple cards, and although the buttons on a card take an array, only one element in that array is allowed.
However, you can do something similar by sending a browsing carousel. This lets you send multiple tiles that include a title and may include images, a body, and a link in the same form that a card has a link.
One issue is that I'm not sure if the link is required to be an http or https link, or if other URL forms are allowed, but keep in mind that not all surfaces that may support links support being able to make telephone calls.
