Connect LINE to Dchat

Before you start

• Difficulty: Medium
• Time: 20 minutes
• You need: A LINE Official Account with a Messaging API channel
• You need: Admin or owner access to your Dchat workspace

Steps

1. Collect your LINE values

   In the LINE Developers console, open your Messaging API channel. Copy the channel secret, issue a long-lived channel access token, and note the bot's user ID (it starts with U).

2. Add the channel in Dchat

   In Dchat, open Settings → Channels and choose + Add channel. Pick "LINE", enter the bot user ID, and paste the credentials. Saving shows your webhook URL.

   { "ChannelSecret": "...", "ChannelAccessToken": "..." }

3. Set the webhook in LINE

   In the Messaging API settings, paste the webhook URL Dchat showed and turn on Use webhook. It has this form:

   https://api.dchat.com/api/inbound/line/{channel id}

4. Send a test message

   Add your account as a friend and send it a message. It appears in your Dchat inbox, and the AI replies if AI is on for your workspace. Turn off LINE's own auto-reply messages so customers don't get two answers.

What goes in each field

• ChannelSecret: From the channel's basic settings; Dchat checks LINE's signature with it.
• ChannelAccessToken: A long-lived channel access token from the Messaging API tab.

Good to know

• One-to-one chats only; text, photos and files (up to 5 MB) are handled.
• Replies are up to 5,000 characters with up to 13 quick replies, sent with LINE's push API.
• Your workspace needs at least one enabled site; new workspaces have one already. Messages are dropped while every site is switched off.
• Credentials are encrypted when you save them and are never shown again. To change one, paste the full credentials again.
