# Conversational Action built-in intents (Dialogflow)

Built-in intents model some of the common ways that users express tasks they're
trying to do or information they seek, such as ordering a meal, booking a ride,
or checking an account balance.

> [!NOTE]
> **Note:** The `actions.intent.PLAY_GAME` intent is the only built-in intent that is generally available at this time. The other intents listed are available in developer preview.

You can use these built-in intents to build [Conversational Actions](https://developers.google.com/assistant/conversational/overview), but we
are still fine tuning Action discovery and ranking. Note that built-in intents
intended for App Actions won't work for Conversational Actions and vice versa.

- If you are building Conversational Actions, you should create and test implicit invocations in addition to registering for built-in intents. To learn more about using and deploying these intents, see the [Built-in intents guide](https://developers.google.com/assistant/df-asdk/discovery/built-in-intents).
- If you are building App Actions, see the [App Actions built-in intent reference](https://developers.google.com/assistant/app/reference/built-in-intents) instead.
