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.
