MoEngage <> Line

MoEngage and Line integration allows you to leverage advanced segmentation, predictive capabilities, personalization, and triggering features to message your users in Line.

Integration

Line allows you to send promotional and non-promotional messages to users, provided your brand has secured their consent. To send to your users, one of the following conditions must be fulfilled:

• Users who have added your Line official account as a friend
• Group chats or multi-person chats in which your Line official account has been joined
• Users who have sent a message to your Line official Account within 7 days in the one-to-one chat (*)

Step 1: Collect User Line IDs

To send messages in Line, you must collect your users’ Line IDs to consistently identify and interact with them. Line IDs are not the same as the user’s Line  usernames. Line IDs are generated by Line and can be used when interacting with Line APIs.

You can obtain Line IDs using the Line User ID API. This endpoint returns a list of Line IDs for all users who have added your Line official account as a friend or sent your account a message and have not blocked you.

When making a GET request to the endpoint https://api.line.me/v2/bot/followers/ids, you will get the followers' Line IDs.

Step 2: Save the User's Line ID on MoEngage

After obtaining a list of Line IDs, you must add them to MoEngage as a line_id, a custom-tracked user attribute or property. You can do one of the following:

• Pass this data to MoEngage using the User Data API.
• Upload it using User Imports inside MoEngage.

Campaign Analytics

MoEngage campaigns provide powerful analytics that allow you to analyze your campaign performances. Each channel in MoEngage provides in-depth metrics that help you quantify your campaign goals. For more information on the MoEngage Analytics functionalities refer to Campaign Analytics.

By default, we provide the following metrics for LINE campaigns:

• Attempted: After removing the users who breached the frequency capping (FC), is calculated as the number of users who qualified for the LINE campaigns and to whom we attempted to send messages.
• Failed: Number of users for whom Line did not send any message or the users for whom we failed to find any value against the user or event attributes used in the campaign.
• Successfully sent: The campaign is marked as successful when LINE APIs accept the request to send the message to users/groups/rooms (with a 200 status code). For more information on LINE Message API responses, refer to their help documentation.
