• Chinese Docs

This project is a third-party LINE Notify SDK.

LINE official didn't provide SDK of Notify function. It's not convenient for developers.

This package is TypeScript compatible and contains TypeScript declarations.

Official LINE Notify API provides endpoints for Authentication and Notification, so does this project.

Authentication API

1. GET https://notify-bot.line.me/oauth/authorize
   • notify.generateOauthURL(state)
2. POST https://notify-bot.line.me/oauth/token
   • notify.getToken(client_code)

Notification API

• GET https://notify-api.line.me/api/status
  • notify.getStatus(token)
• POST https://notify-api.line.me/api/notify
  • notify.notify(token, message, imageThumbnail, imageFullsize, stickerPackageId, stickerId, notificationDisabled)
• POST https://notify-api.line.me/api/revoke
  • notify.revoke(token)

Installation

npm install line-notify-sdk

Usage

Authentication

1. Initialization

Import module and initial sdk object. Constructor's arguments are optional if you have default variables in your environment.

const notifySDK = require('line-notify-sdk')
const notify = new notifySDK(clientID,clientSecret,redirectURI)
// These parameters are optional if you have 
// default variables in your environment

Default environment variables

LINE_NOTIFY_CLIENT_ID=
LINE_NOTIFY_CLIENT_SECRET=
LINE_NOTIFY_REDIRECT_URI=

2. Generate authentication link

notify.generateOauthURL(state)

return [string]

Example ：

const url = notify.generateOauthURL('somerandomstate')

3. Get token from code

notify.getToken(clientCode)

return [promise] resolves to [string]

Example：

const token = await notify.getToken(clientCode)
//token: ZnCpYyTJq7_this_is_user_token_alxj8nWpzBl1

Notification

Initialization

Import module and initial sdk object. Does not require environment variables to send Notifications

const notifySDK = require('line-notify-sdk')
const notify = new notifySDK()

Get token status

notify.getStatus(token)

return [promise] resolves to [object]

Example:

try {
    const info = await notify.getStatus(token)
    // info : { status: 200, message: 'ok', targetType: 'USER', target: 'yiyu0x' }
} catch (error) {
    // error : { status: 4xx, message: 'Invalid access token or other message from LINE'}
}

Send notification

notify.notify(token, message, imageThumbnail, imageFullsize, stickerPackageId, stickerId, notificationDisabled)

return： [promise] resolves to [object]

Example：

// Send a message
notify.notify(token, 'hello').then((body) => {
    console.log(body)
    //{ status: 200, message: 'ok' }
}).catch((e)=>console.log(e))

// Send a sticker
notify.notify(token, 'Here is my sticker', '', '', 1, 1).then((body) => {
    console.log(body)
}).catch((e)=>console.log(e))

Revoke token

notify.revoke(token)

return [promise] resolves to [object]

Example：

// revoke token
notify.revoke(token).then((body) => {
	console.log(body)//{ status: 200, message: 'ok' }
}).catch((e)=>console.log(e))

TypeScript

// your-project.ts

import { notifySDK } from "line-notify-sdk";
const notify = new notifySDK();

notify.generateOauthURL('somerandomstate');
notify.getToken('clientCodeFromCallback');
notify.getStatus('yourToken');
notify.notify('yourMessage');
notify.revoke('yourToken');

Others

• Example Authentication using Express server at example/server.js
• Example Notifications at example/notify.js

API Rate Limits

Reference : LINE Docs

There is a limit to the number of times an API can be called on each service. The default number is set to 1000.

The limit is per access token.

The API Rate Limit status, can be checked on the response header of the API.

| Header name | Description
|:----------:|:------------- | X-RateLimit-Limit | The limit of API calls per hour | X-RateLimit-Remaining | The number of possible remaining API calls | X-RateLimit-ImageLimit | The limit of Uploading image per hour | X-RateLimit-ImageRemaining | The number of possible remaining Uploading image | X-RateLimit-Reset | The time when the limit is reset (UTC epoch seconds)
