Define Actions

Actions are entry points into your app that define the invocation and discovery model for your app. You declare Actions in a JSON file called an Action package, which you eventually upload to your developer project when you want to test or submit your Actions project for approval.

To define Actions in your Action package, you create an intent that defines how the Action is invoked and the corresponding fulfillment endpoint for when the intent is triggered. You can create the following types of Actions:

• Default Action: Every Actions project must have a welcome intent that acts as an entry point for users to start conversations. The welcome intent is triggered when users explicitly invoke an Action by uttering its name (for example, "Ok Google, talk to Sekai"). This welcome intent is identified with the actions.intent.MAIN intent name.

• Additional Actions for deep-linking: You can create additional Actions in your Action package with intents that you define yourself. This allows users to invoke specific functionality by saying an Action name along with an intent (for example: "Ok Google, talk to Sekai to find some shoes").

See Invocation and Discovery for more information on how these invocation models work.

Define a default Action

Every Action package must have one and only one intent that handles the actions.intent.MAIN intent. This intent is triggered when users invoke your Action by name (for example, "Ok Google, talk to Sekai").

Note: You specify your Action name in the project, when you submit your Action package for approval. During testing, you invoke your Action by saying "talk to my test app".

{
  "actions": [
    {
      "description": "Default Welcome Intent",
      "name": "MAIN",
      "fulfillment": {
        "conversationName": "sekaiApp"
      },
      "intent": {
        "name": "actions.intent.MAIN",
        "trigger": {
          "queryPatterns": [
            "talk to sekaiApp"
          ]
        }
      }
    }
  ],
  "conversations": {
    "sekaiApp": {
      "name": "sekaiApp",
      "url": "https://sekai.example.com/sekaiApp"
    }
  },
  "locale": "en"
}

Define additional Actions

You can provide additional Actions that act as entry points. This lets users disambiguate their intent by letting them specify more details about what they want to do (for example, "Ok Google, talk to Sekai to find me some shoes.").

To define additional Actions:

1. In the actions array, specify an Action for every entry point.

   For example, the following sample shows an additional "buy" Action that defines:
   • An intent name of com.example.sekai.BUY
   • parameters to parse from the user input when this intent is triggered. This is useful if you need specific data from the Action phrase when users invoke the Action.
   • queryPatterns that define what users need to say to trigger the intent, which can include Schema.org types that define parameters to parse.

   {
     "description": "Direct access",
     "name": "BUY",
     "fulfillment": {
       "conversationName": "sekaiApp"
     },
     "intent": {
       "name": "com.example.sekai.BUY",
       "parameters": [
         {
           "name": "color",
           "type": "org.schema.type.Color"
         }
       ],
       "trigger": {
         "queryPatterns": [
           "find some $org.schema.type.Color:color sneakers",
           "buy some blue suede shoes",
           "get running shoes"
         ]
       }
     }
   }
         

Note: We recommend around 10 queryPatterns phrases for each intent. These query patterns are used by Google for Action ranking and discovery. They should be representative of your Action's capabilities and indicate how users might want to invoke your Actions.

2. Specify the fulfillment for this intent by specifying a conversationName that corresponds to an item in the conversations object.

   {
     "conversations": {
       "sekaiApp": {
         "name": "sekaiApp",
         "url": "https://sekai.example.com/sekaiApp"
       }
     }
   }
       

Note: You typically will only need one fulfillment endpoint, but Action packages support many.

Here's an example of a full Action package:

{
  "actions": [
    {
      "description": "Default Welcome Intent",
      "name": "MAIN",
      "fulfillment": {
        "conversationName": "sekaiApp"
      },
      "intent": {
        "name": "actions.intent.MAIN",
        "trigger": {
          "queryPatterns": [
            "talk to sekaiApp"
          ]
        }
      }
    },
    {
      "description": "Direct access",
      "name": "BUY",
      "fulfillment": {
        "conversationName": "sekaiApp"
      },
      "intent": {
        "name": "com.example.sekai.BUY",
        "parameters": [
          {
            "name": "color",
            "type": "org.schema.type.Color"
          }
        ],
        "trigger": {
          "queryPatterns": [
            "find some $org.schema.type.Color:color sneakers",
            "buy some blue suede shoes",
            "get running shoes"
          ]
        }
      }
    }
  ],
  "conversations": {
    "sekaiApp": {
      "name": "sekaiApp",
      "url": "https://sekai.example.com/sekaiApp"
    }
  },
  "locale": "en"
