+
+You need the following values:
+
+- `channel_secret`
+- `channel_access_token`

+How to get them:
+
+1. Open your channel settings page
+2. Get `Channel secret` from `Basic settings`

+
+![](/source/images/line/7ecee0a9102f191245330f8408eb0493.png)
+
+## Configure AstrBot
+
+1. Open the AstrBot admin panel
+2. Click `Bots` in the left sidebar
+3. Click `+ Create Bot`
+4. Select `line`
+
+Fill in these fields:
+
+- `ID`: Custom identifier to distinguish instances
+- `Enable`: Checked
+- `LINE Channel Access Token`: your `channel_access_token`
+- `LINE Channel Secret`: your `channel_secret`
+- `LINE Bot User ID`: optional; if empty, AstrBot uses webhook `destination`
+
+Click Save.
+
+## Configure Callback URL (Unified Webhook)
+
+The LINE adapter supports **unified webhook mode only**.
+
+After saving, click `View Webhook URL` on the bot card and copy the URL.
+
+Then in LINE Developers Console:
+
+1. Open `Messaging API`
+2. Paste the URL into `Webhook settings` -> `Webhook URL`
+3. Click `Verify`
+4. Enable `Use webhook`
+
+> [!TIP]
+> If AstrBot is not publicly reachable, set up a public domain and reverse proxy first so LINE can access your webhook URL.
+
+## Test
+
+1. Add your Official Account as a friend in LINE
+2. Send a message to the bot (for example, `hi`)
+3. If the bot replies, setup is successful
+
+If you want to use it in a group, invite the Official Account to the group first.
