# 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.
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
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 Send narrowcast messages.
# Share audiences
The Messaging API and the LINE Official Account Manager (opens new window) can use the audiences created for the same LINE Official Account with each other. There are no initial settings required to use audiences with each other.
If you want to use audiences between the Messaging API and tools other than the LINE Official Account Manager (such as the LINE Ads Manager (opens new window)), you will need to set up audience sharing. For more information about how to share audiences, see Share your audience in Business Manager.
Tool that creates audience | Tool that uses audience | Availability of audience |
---|---|---|
Messaging API | LINE Official Account Manager | ✅ |
LINE Official Account Manager | Messaging API | ✅ |
Messaging API | Tools other than LINE Official Account Manager | ✅ *1 |
Tools other than LINE Official Account Manager | Messaging API | ✅ *1 |
*1 Available if you share the audience in the Business Manager.
# Share your audience in Business Manager
The Business Manager (opens new window) allows you to share specific audiences across multiple services (such as the LINE Ads Manager) and use the audiences with each other.
You can share audiences between Messaging API channels under the same provider by using the audience sharing function in the Business Manager. However, only verified accounts and premium accounts can set audience sharing in the Business Manager.
You can get data of the shared audience in Business Manager by using the following endpoints:
For more information on how to share audiences, see Sharing Resources (opens new window) (only available in Japanese) in the Business Manager manual.
