Rich response messages

This integration translates some rich response messages messages to Hangouts Chat message formats.

Text Responses

Text responses are sent to Hangouts as SimpleText. With this formatting you can make text bold or italics by wrapping the text in certain (markdown light) symbols.

The SimpleText response, visually looks the same as the Default Text Response in the Dialogflow Console. However, the raw API response will look a bit different. It also sets the platform config to GOOGLE_HANGOUTS, which could be interesting when building agents for multiple integrations.

"fulfillmentMessages": [
   "text": {
   "text": [
        "This is a test."
  "platform": "GOOGLE_HANGOUTS"


Image responses are sent to Hangouts as Hangouts Image Widgets.


Card responses are sent to Hangouts as Hangouts Cards.

Custom Payload

To send other types of Hangouts messages, you can use a custom payload.

Hangouts Custom Payload allows you to create more advanced cards. One card can have one or many sections. Each section could have a header. You can have a look into the hangouts message formats cards reference guide, to see some of the combinations you can create with this. However, using custom payloads means that you will have to provide the JSON format.

Here's a working example:

  "hangouts": {
    "header": {
      "title": "Pizza Bot Customer Support",
      "subtitle": "pizzabot@example.com",
      "imageUrl": "https://goo.gl/aeDtrS"
    "sections": [{
      "widgets": [{
        "keyValue": {
          "icon": "TRAIN",
          "topLabel": "Order No.",
          "content": "12345"
        "keyValue": {
          "topLabel": "Status",
          "content": "In Delivery"
      "header": "Location",
      "widgets": [{
        "image": {
          "imageUrl": "https://dummyimage.com/600x400/000/fff"
      "header": "Buttons - i could leave the header out",
      "widgets": [{
        "buttons": [{
          "textButton": {
            "text": "OPEN ORDER",
            "onClick": {
              "openLink": {
                "url": "https://example.com/orders/..."
