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 for common answers.

Troubleshooting

If messages do not arrive, check that the webhook is on and the URL matches exactly. See troubleshooting. Other chat apps: Viber and Telegram. All channels are listed in the channels overview.

Common questions

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