LIFF Server API Client

Description

This is a LIFF Server API client that is implemented by using TypeScript.\ This provides the simple CRUD interfaces for your LIFF apps.

Installation

% npm install liff-server-api

Usage

Issue access token

According to the LIFF Server API reference, a channel access token is required to call any LIFF Server API endpoints.\ The snippet below issues a channel access token.\ * Note: Replace {YOUR_CHANNEL_ID} and {YOUR_CHANNEL_SECRET} with your own credentials.

import { 
    MessageApiClient,
    IssueAccessTokenRequest,
    MessageApiResponse
} from 'liff-server-api';

const baseUrl = 'https://api.line.me';
const client = new MessageApiClient(baseUrl);
const request: IssueAccessTokenRequest 
    = new IssueAccessTokenRequest({
        channelId: '{YOUR_CHANNEL_ID}',
        channelSecret: '{YOUR_CHANNEL_SECRET}'
    });
const response: MessageApiResponse = await client.issueAccessToken(request);
const accessToken = response.access_token;
console.debug('access token: %s', accessToken);

Invoke LIFF Server API

Once you get a channel access token, you next initialize the LiffApiClient object with the channel access token.\ Then, you're ready to call the server API.\ The snippet below initializes the LiffApiClient and invokes the getAll() method that calls the /liff/v1/apps endpoint which provides all the LIFF apps belonging to your channel.

import {
    LiffApiClient,
    LiffAppGetRequest,
    LiffApiGetRespoinse
} from 'liff-server-api';

const baseUrl = 'https://line.api.me';
const client: LiffApiClient = new LiffApiClient(baseUrl);
const request: LiffAppGetRequest
    = new LiffAppGetRequest({
            channelAccessToken: '{YOUR_ACCESS_TOKEN}'
    });
const response: LiffApiGetRespoinse = await client.getAll(request);
console.debug('Your LIFF apps: %O', response.apps);
