Enable LINE Channel for New Bottender App

Create Bottender App is the best way to start a new bot application in Bottender.

To create a new application, run:

npx create-bottender-app my-app

Please make sure the line option is enabled:

After finishing Create Bottender App process, bottender.config.js, a config file, will be generated automatically for furthur LINE channel settings.

Enable LINE Channel for Existing Apps

Firstly, you need to have a bottender.config.js under application root folder, then set channels.line.enabled to true:

module.exports = {
  channels: {
    line: {
      enabled: true,
      path: '/webhooks/line',
      accessToken: process.env.LINE_ACCESS_TOKEN,
      channelSecret: process.env.LINE_CHANNEL_SECRET,
    },
  },
};

The default webhook path is /webhooks/line, but you can set your own webhook path in the path field.

Complete LINE Channel Settings

To make a LINE bot work, you have to setup three values:

• LINE Access Token
• LINE Channel Secret
• Webhook

LINE Access Token & Channel Secret

bottender.config.js looks up .env for LINE access token and LINE channel secrect. Those two values have to be copied from LINE@ account settings and pasted to the the following fields in .env.

LINE_ACCESS_TOKEN=
LINE_CHANNEL_SECRET=

Note:

• It is recommended to develop your LINE Bot with your developer LINE@ account, furthur information could be found in LINE's official article, Getting Started.
• Your LINE@ accounts could be accessed from your provider list.
• To get your LINE access token and LINE channel secrect, you may refer to LINE's official article, Building a Bot.

Webhook

After finishing above settings, you can start your server with LINE webhook event listening using following commands:

# in production mode
npm start

# or in development mode
npm run dev

Then, you have to manually copy your webhook url to LINE@ account's setting page. Finally, you are ready to interact with your bot on LINE :)

Note:

• For furthur instruction of webhook setting, please check LINE's official article, Building a Bot.
