Create a Messaging API channel, save its secret and long-lived token in Frosvo, set the webhook in LINE and turn off auto-replies so customers' LINE messages reach your inbox.

LINE is widely used in parts of Asia. Connect your Official Account so those customers reach the same inbox as everyone else.

## What you need

- A LINE Official Account and a **Messaging API channel** in the LINE Developers console.
- Owner or **Channels** permission in Frosvo.

## Steps

1. In the LINE Developers console create a **Messaging API** channel.
2. Copy the **Channel secret** and issue a **long-lived channel access token**.
3. In Frosvo go to **Channels**, click **Add channel** and choose **LINE**. Pick the website, name the connection and paste both values.
4. Click **Save and check**.
5. Copy the address shown under **Steps to turn it on** in Frosvo. In LINE set it as the **Webhook URL**, switch on **Use webhook**, and switch **off** auto-reply messages.
6. Then tick **I have added this address in LINE**.
7. Make sure **Account checked** has a tick, then click **Turn on messaging**.
8. Message your Official Account and confirm the chat appears in the **Inbox**, then reply.

## What to expect

Customers' LINE messages appear as conversations from LINE. LINE signs every request with your channel secret and Frosvo verifies it, so forged messages are ignored.

## Tips

- Keep your channel secret and access token private. Saved secrets are never shown again in Frosvo.
- Re-issue the token in LINE if you ever suspect it leaked, then paste the new one in Frosvo.
- Match your brand's tone in replies, and use [shared replies](/docs/saved-replies-and-macros) for common answers.

## Troubleshooting

If messages do not arrive, check that the webhook is on and the URL matches exactly. See [troubleshooting](/docs/troubleshooting). Other chat apps: [Viber](/docs/viber-setup) and [Telegram](/docs/telegram-setup). All channels are listed in the [channels overview](/docs/channels).

## Common questions

**What if the secret changes?** Update it in Frosvo and save, leaving the other fields as they are.

**Why do customers get an automatic LINE answer?** The built-in auto-reply is still on. Switch it off in LINE and keep Use webhook on.

## Common questions

### Why must I turn off auto-reply messages in LINE?

LINE's built-in auto-replies would answer customers before your team or Frosvo can, so they are turned off.

### Which token do I need?

The long-lived channel access token, issued in the LINE Developers console, plus the channel secret.

### How does Frosvo know a message is from LINE?

LINE signs each request with the channel secret, and Frosvo checks the signature.
