# Postback action
The postback action sends your server a postback event with the text that you specified in the action. You can set to have the text displayed as a message from the user.
You can also specify how to display such as rich menu based on user action. The following display methods can be specified:
- Close rich menu
- Open rich menu
- Open keyboard
- Open voice message input mode
Specifying how to display based on user action is available on LINE version 12.6.0
or later for iOS or Android. For more information, see Postback action in the Messaging API reference.
# Message action
The message action returns you a text as a user's message. For more information, see Message action in the Messaging API reference.
# URI action
The URI action opens a URL in LINE's in-app browser. You can also use the LINE URL scheme in the URI action to launch a call app with a given number or open the screen to share any LINE Official Account.
This is a request body set with URI actions for the quick reply buttons shown in the example above. For more information, see URI action in the Messaging API reference.
