    object (CardHeader)
  },
  "sections": [
    {
      object (Section)
    }

  },
  "displayStyle": enum (DisplayStyle),
  "peekCardHeader": {
    object (CardHeader)
  }
}

object ( CardHeader )

The header of the card. A header usually contains a leading image and a title. Headers always appear at the top of a card.

object ( Section )

Contains a collection of widgets. Each section has its own, optional header. Sections are visually separated by a line divider.

object ( CardAction )

The card's actions. Actions are added to the card's toolbar menu.

Because Chat app cards have no toolbar, cardActions[] is not supported by Chat apps.

For example, the following JSON constructs a card action menu with Settings and Send Feedback options:

"cardActions": [
  {
    "actionLabel": "Settings",
    "onClick": {
      "action": {
        "functionName": "goToView",
        "parameters": [
          {
            "key": "viewType",
            "value": "SETTING"
         }
        ],
        "loadIndicator": "LoadIndicator.SPINNER"
      }
    }
  },
  {
    "actionLabel": "Send Feedback",
    "onClick": {
      "openLink": {
        "url": "https://example.com/feedback"
      }
    }
  }
]

string

Name of the card. Used as a card identifier in card navigation.

Because Chat apps don't support card navigation, they ignore this field.

object ( CardFixedFooter )

The fixed footer shown at the bottom of this card.

Setting fixedFooter without specifying a primaryButton or a secondaryButton causes an error.

Chat apps support fixedFooter in dialogs , but not in card messages .

enum ( DisplayStyle )

In Google Workspace add-ons, sets the display properties of the peekCardHeader .

Not supported by Chat apps.

object ( CardHeader )

When displaying contextual content, the peek card header acts as a placeholder so that the user can navigate forward between the homepage cards and the contextual cards.

Not supported by Chat apps.

{
  "title": string,
  "subtitle": string,
  "imageType": enum (ImageType),
  "imageUrl": string,
  "imageAltText": string
}

string

Required. The title of the card header. The header has a fixed height: if both a title and subtitle are specified, each takes up one line. If only the title is specified, it takes up both lines.

string

The subtitle of the card header. If specified, appears on its own line below the title .

enum ( ImageType )

The shape used to crop the image.

string

The HTTPS URL of the image in the card header.

string

{
  "header": string,
  "widgets": [
    {
      object (Widget)

}

string

Text that appears at the top of a section. Supports simple HTML formatted text .

object ( Widget )

All the widgets in the section. Must contain at least 1 widget.

boolean

Collapsible sections hide some or all widgets, but users can expand the section to reveal the hidden widgets by clicking Show more . Users can hide the widgets again by clicking Show less .

To determine which widgets are hidden, specify uncollapsibleWidgetsCount .

integer

The number of uncollapsible widgets which remain visible even when a section is collapsed.

For example, when a section contains five widgets and the uncollapsibleWidgetsCount is set to 2 , the first two widgets are always shown and the last three are collapsed by default. The uncollapsibleWidgetsCount is taken into account only when collapsible is true .

        }
      }
    }
  ]
}

object ( TextInput )

Displays a text box that users can type into.

For example, the following JSON creates a text input for an email address:

"textInput": {
  "name": "mailing_address",
  "label": "Mailing Address"
}

As another example, the following JSON creates a text input for a programming language with static suggestions:

"textInput": {
  "name": "preferred_programing_language",
  "label": "Preferred Language",
  "initialSuggestions": {
    "items": [
      {

      "selected": false
    }
  ]
}

object ( DateTimePicker )

{

  // Union field data can be only one of the following:
  "action": {
    object (Action)
  },
  "openLink": {
    object (OpenLink)
  },
  "openDynamicLinkAction": {
    object (Action)
  },
  "card": {
    object (Card)
  }
  // End of list of possible types for union field data.
}

object ( Action )

If specified, an action is triggered by this onClick .

object ( OpenLink )

If specified, this onClick triggers an open link action.

object ( Action )

An add-on triggers this action when the action needs to open a link. This differs from the openLink above in that this needs to talk to server to get the link. Thus some preparation work is required for web client to do before the open link action response comes back.

object ( Card )

A new card is pushed to the card stack after clicking if specified.

Supported by Google Workspace Add-ons, but not Chat apps.

{
  "function": string,
  "parameters": [
    {
      object (ActionParameter)
    }
  ],
  "loadIndicator": enum (LoadIndicator),
  "persistValues": boolean,
  "interaction": enum (Interaction)
}

string

A custom function to invoke when the containing element is clicked or othrwise activated.

For example usage, see Create interactive cards .

object ( ActionParameter )

List of action parameters.

enum ( LoadIndicator )

Specifies the loading indicator that the action displays while making the call to the action.

boolean

Indicates whether form values persist after the action. The default value is false .

If true , form values remain after the action is triggered. To let the user make changes while the action is being processed, set LoadIndicator to NONE . For card messages in Chat apps, you must also set the action's ResponseType to UPDATE_MESSAGE and use the same cardId from the card that contained the action.

If false , the form values are cleared when the action is triggered. To prevent the user from making changes while the action is being processed, set LoadIndicator to SPINNER .

enum ( Interaction )

Optional. Required when opening a dialog .

What to do in response to an interaction with a user, such as a user clicking button on a card message.

If unspecified, the app responds by executing an action - like opening a link or running a function - as normal.

By specifying an interaction , the app can respond in special interactive ways. For example, by setting interaction to OPEN_DIALOG , the app can open a dialog .

When specified, a loading indicator is not shown.

Supported by Chat apps, but not Google Workspace Add-ons. If specified for an add-on, the entire card is stripped and nothing is shown in the client.

  // End of list of possible types for union field control.
}

object ( Icon )

Deprecated in favor of startIcon .

object ( Icon )

The icon displayed in front of the text.

string

The text that appears above text . Always truncates.

string

Required. The primary text.

Supports simple formatting. See Text formatting for formatting details.

boolean

The wrap text setting. If true , the text wraps and displays on multiple lines. Otherwise, the text is truncated.

Only applies to text , not topLabel and bottomLabel .

string

The text that appears below text . Always truncates.

object ( OnClick )

When users click on topLabel or bottomLabel , this action triggers.

object ( Button )

A button that can be clicked to trigger an action.

object ( SwitchControl )

A switch widget can be clicked to change its state and trigger an action.

  // Union field icons can be only one of the following:
  "knownIcon": string,
  "iconUrl": string
  // End of list of possible types for union field icons.
}

string

Optional. A description of the icon used for accessibility. If unspecified, the default value "Button" is provided. As a best practice, you should set a helpful description for what the icon displays, and if applicable, what it does. For example, A user's account portrait , or Opens a new browser tab and navigates to the Google Chat developer documentation at https://developers.google.com/chat .

If the icon is set in a Button , the altText appears as helper text when the user hovers over the button. However, if the button also sets text , the icon's altText is ignored.

enum ( ImageType )

The crop style applied to the image. In some cases, applying a CIRCLE crop causes the image to be drawn larger than a built-in icon.

string

Display one of the built-in icons provided by Google Workspace.

For example, to display an airplane icon, specify AIRPLANE . For a bus, specify BUS .

For a full list of supported icons, see built-in icons .

string

Display a custom icon hosted at an HTTPS URL.

For example:

"iconUrl":
"https://developers.google.com/chat/images/quickstart-app-avatar.png"

Supported file types include .png and .jpg .

{
  "text": string,
  "icon": {
    object (Icon)
  },
  "color": {
    object (Color)
  },
  "onClick": {
    object (OnClick)
  },
  "disabled": boolean,
  "altText": string
}

string

The text displayed inside the button.

object ( Icon )

The icon image. If both icon and text are set, then the icon appears before the text.

object ( Color )

If set, the button is filled with a solid background color and the font color changes to maintain contrast with the background color. For example, setting a blue background will likely result in white text.

If unset, the image background is white and the font color is blue.

For red, green and blue, the value of each field is a float number that can be expressed in either of two ways: as a number between 0 and 255 divided by 255 (153/255) or as a value between 0 and 1 (0.6). 0 represents the absence of a color and 1 or 255/255 represent the full presence of that color on the RGB scale.

Optionally set alpha, which sets a level of transparency using this equation:

pixel color = alpha * (this color) + (1.0 - alpha) * (background color)

For alpha, a value of 1 corresponds with a solid color, and a value of 0 corresponds with a completely transparent color.

For example, the following color represents a half transparent red:

"color": {
   "red": 1,
   "green": 0,
   "blue": 0,
   "alpha": 0.5
}

object ( OnClick )

Required. The action to perform when the button is clicked, such as opening a hyperlink or running a custom function.

boolean

If true , the button is displayed in an inactive state and doesn't respond to user actions.

string

The alternative text used for accessibility.

Set descriptive text that lets users know what the button does. For example, if a button opens a hyperlink, you might write: "Opens a new browser tab and navigates to the Google Chat developer documentation at https://developers.google.com/chat" .

{
  "red": number,
  "green": number,
  "blue": number,
  "alpha": number
}

number

The amount of red in the color as a value in the interval [0, 1].

number

The amount of green in the color as a value in the interval [0, 1].

number

The amount of blue in the color as a value in the interval [0, 1].

number

The fraction of this color that should be applied to the pixel. That is, the final pixel color is defined by the equation:

pixel color = alpha * (this color) + (1.0 - alpha) * (background color)

This means that a value of 1.0 corresponds to a solid color, whereas a value of 0.0 corresponds to a completely transparent color. This uses a wrapper message rather than a simple float scalar so that it is possible to distinguish between a default value and the value being unset. If omitted, this color object is rendered as a solid color (as if the alpha value had been explicitly given a value of 1.0).

{
  "name": string,
  "value": string,
  "selected": boolean,
  "onChangeAction": {
    object (Action)

Examples of changes include a user adding to the field, or deleting text.

Examples of actions to take include running a custom function or opening a dialog in Google Chat.

object ( Suggestions )

Suggested values that users can enter. These values appear when users click inside the text input field. As users type, the suggested values dynamically filter to match what the users have typed.

For example, a text input field for programming language might suggest Java, JavaScript, Python, and C++. When users start typing "Jav", the list of suggestions filters to show just Java and JavaScript.

Suggested values help guide users to enter values that your app can make sense of. When referring to JavaScript, some users might enter "javascript" and others "java script". Suggesting "JavaScript" can standardize how users interact with your app.

When specified, TextInput.type is always SINGLE_LINE , even if it is set to MULTIPLE_LINE .

object ( Action )

Optional. Specify what action to take when the text input field provides suggestions to users who interact with it.

If unspecified, the suggestions are set by initialSuggestions and are processed by the client.

If specified, the app takes the action specified here, such as running a custom function.
