LINE Overview

LINE is a Japan-based, cross-platform popular messaging app and social media platform primarily used in Asian countries. The key features include Messaging, Stickers, a Timeline, Vice and Video calls, Games and Entertainment and Official accounts.

To connect to a LINE channel a LINE Official Account is required. You can create a LINE Official Account here. If you already have a LINE Official account, proceed with connecting your LINE Official Account to respond.io.

Pricing

LINE Official Accounts are free to create. The free Communication plan has a messaging limit of 500.

Paid plan accounts come in two tiers - Light and Standard. These accounts can exceed the paid plan message limit but will incur fees for each additional message sent. You can learn more about the plans here.

Capturing Conversation

To start a conversation, LINE requires users to send you the first message. This is to prevent brands from spamming users.

There are two ways to encourage users to initiate a chat:

You can use Chat links in texts, images, and buttons. These links can be shared in text messages, emails, websites or social media, enabling customers to quickly find your Official Account to chat with you on LINE.

Learn how to create a LINE link here.

Limitation: The links do not work on the LINE desktop app. When users click the LINE links on their desktop, it will either open the official LINE website or pull up a page with a QR code which the Contacts can scan with the LINE app on their phone to initiate the conversation.

QR Codes

Use QR Codes in physical stores to encourage customers to scan on their mobile devices and initiate a chat with your business on LINE. Learn how to generate a QR Code here.

Messaging Window

LINE has no messaging window as long as you remain in a customer’s contact list.

The Contact will not receive any message if they block you. However, if the Contact unblocks your account, you will receive a Welcome Event notification on the conversation history on the respond.io platform and the Contact will be able to receive your message again.

However, LINE has certain messaging limits. These limits are in place to prevent spam and misuse of the platform. The messaging limit will be based on your LINE subscription plan.

Broadcasts

You can send broadcasts to LINE Contacts using the respond.io platform.

LINE has no restrictions on broadcast message content. However, the available number of broadcast messages is limited to your LINE subscription plan and respond.io plan.

Broadcast messages that exceed the monthly limit will fail to send.

You won’t be able to import Contacts to the respond.io platform directly to broadcast the messages. You will need to build your Contact list by getting Contacts to send you the first message. Read more on how to get Contacts to start a conversation.

Rate Limits

A rate limit is the number of API calls an app or user can make within a given time period defined by the channel. Learn more about the rate limits of this channel.
