Configuration

Add following entry in configuration.yaml

    platform: line_bot
    client_id: 'CLIENT_ID'
    access_token: 'CHANNEL_ACCESS_TOKEN'

Add more profile via UI

A profile means a set of client_id and access_token.

You can add more notify service by repeating above steps. You can also create profile via UI to simplify the process

1. Configuration > Integration > Add Integration > LINE Bot
2. Enter profile name (different to entry name in configuration.yaml), client_id and access_token.

See Change Profile to learn how to use profile

Usage

Passing LINE message object into service

service: notify.line_bot
data:
  message: >-
    {"messages":[{"type": "text", "text": "Hello, world"}]}

Just in case you are too lazy to pass full object, plain text is also supported

service: notify.line_bot
data:
  message: 'Hello, world'

Change profile

service: notify.line_bot
data:
  message: >-
    {"messages":[{"type": "text", "text": "Hello, world"}]}
  data:
    profile: cool_line_bot # Profile name

See Additional Information for detail of LINE Message Object

Additional Information

client_id

client_id is LINE user ID or group ID

Retrieve client_id can be tricky, here's how I get client_id

1. Create Firebase Cloud Functions
2. Deploy following script to Cloud Functions

const functions = require('firebase-functions')

exports.helloWorld = functions.https.onRequest((request, response) => {
  const events = request.body.events
  const source = events.length > 0 ? events[0].source : null

  if (source) {
    functions.logger.info(source.groupId || source.userId)
  }
  response.send('Hello from Firebase!')
})

3. Enable webhook for LINE Messaging API
4. Friend bot account or invite bot to your group chat
5. You should be able to see client_id in Cloud Functions log after sending some nice message to your bot
6. Disable webhook again or your log will be flooded

access_token

access_token is channel access token which can be generate from LINE Developer website

Visit https://developers.line.biz/console/channel/<YOUR CHANNEL ID>/messaging-api

The token is listed under Channel access token or your can create one there
