Botpress Cloud: Messaging Channels
Line

Requirements
You will need to create a channel on the LINE Developers Console, and then add that channel to your LINE official account.
Create a Meta App & Business Account
To create a channel and add it to your official account, you can read the Getting started with the Messaging API. The next step is configuring the Messaging API Webhook Settings.
When you have created everything and are ready for the next step, go to the next section.
Channel Configuration
To add LINE integration configuration, go to your bot's configuration screen. Then go to the channel tab, and click on LINE.
A screen will pop up asking for the following details:
1. Channel Access Token
The Channel Access Token is the means of authentication for the channel. You are deemed to have permission to use the channel if the Access Token is correct.
To get the Channel Access Token: in your channel configuration, open the Messaging API tab, scroll to the bottom to the Channel Access Token section, and then generate a new one or copy it if the Channel access token was already issued.
For Long-Lived Channel Access Token: read this LINE documentation.
2. Channel Secret
The Channel Secret is used to verify the signature between LINE and Botpress.
To get the Channel Secret: in your channel configuration, open the Basic settings tab, scroll to the bottom to the Channel Secret section, and then copy the secret.
Finalizing Channel Configuration
The next step is to Enable the channel from the top of the screen and copy the webhook URL from the button below the webhook URL. Then click Save.
Now, we proceed to the last step by setting your webhook URL in LINE.
