For example usage, see Read form data.

ActionParameter

List of action parameters.

LoadIndicator

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

bool

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 card_id 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.

Interaction

Optional. Required when opening a dialog.

What to do in response to an interaction with a user, such as a user clicking a button in 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 isn't shown. If specified for an add-on, the entire card is stripped and nothing is shown in the client.
