# Messaging Send messages and search the user’s received messages. ## Discussion With messaging intents, users can ask Siri to compose new messages, read existing messages, and indicate to other users whether they’re available. To allow users to compose and send text or audio messages with your service, support [`INSendMessageIntent`](/documentation/Intents/INSendMessageIntent). Donate interactions when the user sends and receives messages in your app to give the system cues about which contacts to suggest in Share Sheets. Support [`INSearchForMessagesIntent`](/documentation/Intents/INSearchForMessagesIntent) and [`INSetMessageAttributeIntent`](/documentation/Intents/INSetMessageAttributeIntent) to allow Siri to announce incoming messages on AirPods, and mark announced messages as [`INMessageAttribute.read`](/documentation/Intents/INMessageAttribute/read) or [`INMessageAttribute.played`](/documentation/Intents/INMessageAttribute/played). Adopting [`INSearchForMessagesIntent`](/documentation/Intents/INSearchForMessagesIntent) also enables users to see incoming messages on a [`INCarAudioSource.sourceCarPlay`](/documentation/Intents/INCarAudioSource/sourceCarPlay)-enabled display.  In iOS, you can use an Intents UI app extension to display a custom message composition interface. ## Topics ### Essentials ### Sending a Message [`INSendMessageIntentHandling`](/documentation/Intents/INSendMessageIntentHandling) An interface to handle sending messages to one or more designated users.
