We made several improvements to the Messaging API.

# Use LINE emoji in messages

In addition to standard unicode emoji and (deprecated) LINE original emoji, you can now include LINE emoji when you send a text message with the Messaging API.

LINE emoji are identified by a productId and emojiId:

// Text message example with LINE emoji
{
    "type": "text",
    "text": "Look at this: $ It's a LINE emoji!",
    "emojis": [
        {
            "index": 14,
            "productId": "5ac1bfd5040ab15980c9b435",
            "emojiId": "001"
        }
    ]
}

For details, see the Text message section in the Messaging API reference.

# Get user's language

The Get profile endpoint now returns a language property in addition to other user profile information, provided one of these situations applies:

  • User has a LINE account created in Japan and has agreed to the Privacy Policy of LINE version 8.0.0 or later
  • User has a LINE account created in Taiwan, Thailand, or Indonesia and has agreed to the Privacy Policy of LINE version 8.9.0 or later

# Multicast recipient limit removed

Previously, messages sent with the Send multicast message endpoint were limited to a maximum number of recipients. This limit has been removed. Other rate limits remain in place. See this table for a comparison of the previous and current situation:

Bot type Previous limitations Current limitations
Bots associated with LINE Official Accounts 100,000 requests per minute
1,700 requests per second*
2,000,000 recipients per minute
100,000 requests per minute
1,700 requests per second*
Bots associated with LINE@ accounts 10,000 requests per minute
170 requests per second*
200,000 recipients per minute
10,000 requests per minute
170 requests per second*

* The rate limit in seconds is a guideline for mass transmission.

In addition, you can now target up to 500 user IDs (increased from 150) with a single multicast message.

For more details, see the Rate limits section of the Messaging API reference.
