# Use audiences

Audiences help you to apply advanced targeting. For example, you can target a group of users who read your message or clicked a URL in a message.


Only the LINE Official Accounts created by users in Japan, Thailand and Taiwan are permitted to create audiences.

To use Identifiers for Advertisers (IFA)

You can use IFAs to specify recipients, but this is only available to corporate users who submit an application form. To use IFA with your LINE Official Account, contact your sales representative or contact our Sales partners (opens new window).

# Create an audience

You can use the Messaging API to create audiences. Supported audience types are:

Audience Description
Audience for uploading user IDs A set of users specified with user IDs or IFA (Identifier For Advertisers)
Message click audience A set of users who clicked a URL in a message sent
Message impression audience A set of users who read a message sent

You can't create the following types of audiences with the Messaging API:

  • Chat tag audience
  • Friend path audience
  • Reservation audience
  • Rich menu impression audience
  • Rich menu click audience
  • Web traffic audience
  • App event audience
  • Video view audience
  • Image click audience
Limit on concurrent operations

For user ID based audiences, the number of concurrent endpoint operations is limited per audience ID (audienceGroupId). This limitation is applied on creating an audience for uploading user IDs and adding user IDs to an audience. For more information, see Limit on the number of concurrent operations.

# Use audiences

You can use audiences to send narrowcast messages. For more information, see Sending messages to multiple users via attribute data or retargeting (narrowcast messages).

# Share audiences

You can make the audiences you create with the Messaging API accessible by LINE Official Account Manager (opens new window) and LINE Ad Manager (opens new window). You can also use the audiences created from the manager services, with the Messaging API. We call this audience sharing. For instance, although you can't create a chat tag or friend path audience with the Messaging API, you can use those audiences through sharing.

If an audience isn't to be shared, change the audience's authority level to PRIVATE. For more information, see Change the authority level of the audience in the Messaging API references.
