LINE Messaging API SDK for PHP

Build Status

Introduction

The LINE Messaging API SDK for PHP makes it easy to develop bots using LINE Messaging API, and you can create a sample bot within minutes.

Documentation

See the official API documentation for more information.

Requirements

  • PHP 8.1 or later

Installation

Install the LINE Messaging API SDK using Composer.

$ composer require linecorp/line-bot-sdk

Getting started

Create the bot client instance

The bot client instance is a handler of the Messaging API.

$client = new \GuzzleHttp\Client();
$config = new \LINE\Clients\MessagingApi\Configuration();
$config->setAccessToken('<channel access token>');
$messagingApi = new \LINE\Clients\MessagingApi\Api\MessagingApiApi(
  client: $client,
  config: $config,
);

You must use the Client with GuzzleHttp\ClientInterface implementation.

Call API

You can call an API through the messagingApi instance.

A very simple example:

$message = new TextMessage(['type' => 'text','text' => 'hello!']);
$request = new ReplyMessageRequest([
    'replyToken' => '<reply token>',
    'messages' => [$message],
]);
$response = $messagingApi->replyMessage($request);

This procedure sends a message to the destination that is associated with <reply token>.

We also support setter style.

$message = (new TextMessage())
  ->setType(\LINE\Constants\MessageType::TEXT)
  ->setText('hello!');
$request = (new ReplyMessageRequest)
  ->setReplyToken('<reply token>')
  ->setMessages([$message]);
try {
  $messagingApi->replyMessage($request);
  // Success
} catch (\LINE\Clients\MessagingApi $e) {
  // Failed
  echo $e->getCode() . ' ' . $e->getResponseBody();
}

Components

Webhook

LINE's server sends user actions (such as a message, image, or location) to your bot server. Request of that contains event(s); event is action of the user.

The following shows how the webhook is handled:

  1. Receive webhook from LINE's server.
  2. Parse request payload by EventRequestParser#parseEventRequest($body, $channelSecret, $signature).
  3. Iterate parsed events and some react as you like.

The following examples show how webhooks are handled:

Hints

Examples

This repository contains two examples of how to use the LINE Messaging API.

EchoBot

A simple sample implementation. This application reacts to text messages that are sent from users.

KitchenSink

A full-stack (and slightly complex) sample implementation. This application demonstrates a practical use of the LINE Messaging API.

PHPDoc

https://line.github.io/line-bot-sdk-php/

This library provides PHPDoc to describe how to use the methods. You can generate the documentation using phpDocumenter using the following command.

$ wget https://github.com/phpDocumentor/phpDocumentor/releases/download/v3.3.1/phpDocumentor.phar $ php phpDocumentor.phar run -d src -t docs The HTML files are generated in docs/.

Official API documentation

Official API documents shows the detail of Messaging API and fundamental usage of SDK.

Laravel Support

Easy to use from Laravel. After installed, add LINE_BOT_CHANNEL_ACCESS_TOKEN to .env

LINE_BOT_CHANNEL_ACCESS_TOKEN=<Channel Access Token>

then you can use facades like following.

$profile = \LINEMessagingApi::pushMessage(....);

Facade uses \GuzzleHttp\Client by default. If you want to change the config, run

$ php artisan vendor:publish --tag=config

Then line-bot.php will be published to config/ dir. If you want to configure a custom header, do the following.

return [
    'channel_access_token' => env('LINE_BOT_CHANNEL_ACCESS_TOKEN'),
    'channel_id' => env('LINE_BOT_CHANNEL_ID'),
    'channel_secret' => env('LINE_BOT_CHANNEL_SECRET'),
    'client' => [
        'config' => [
          'headers' => ['X-Foo' => 'Bar'],
        ],
    ],
];
