SDK of the LINE Messaging API for PHP.
See the official API documentation for more information.
English: https://developers.line.me/en/docs/
Japanese: https://developers.line.me/ja/docs/
Install the LINE Messaging API SDK using Composer.
$ composer require linecorp/line-bot-sdk
The bot client instance is a handler of the Messaging API.
$httpClient = new \LINE\LINEBot\HTTPClient\CurlHTTPClient('<channel access token>');
$bot = new \LINE\LINEBot($httpClient, ['channelSecret' => '<channel secret>']);The constructor of the bot client requires an instance of HTTPClient.
This library provides CurlHTTPClient by default.
You can call an API through the bot client instance.
A very simple example:
$response = $bot->replyText('<reply token>', 'hello!');This procedure sends a message to the destination that is associated with <reply token>.
A more advanced example:
$textMessageBuilder = new \LINE\LINEBot\MessageBuilder\TextMessageBuilder('hello');
$response = $bot->replyMessage('<reply token>', $textMessageBuilder);
if ($response->isSucceeded()) {
echo 'Succeeded!';
return;
}
// Failed
echo $response->getHTTPStatus() . ' ' . $response->getRawBody();LINEBot#replyMessage() takes the reply token and MessageBuilder.
The method sends a message that is built by MessageBuilder to the destination.
The type of message that is sent depends on the type of instance of MessageBuilder.
For example, the method sends a text message if you pass TextMessageBuilder and it sends an image message if you pass ImageMessageBuilder.
For more detailed information on MessageBuilder, see \LINE\LINEBot\MessageBuilder and the namespace.
Other methods that take MessageBuilder behave in the same way.
Methods that call API returns Response. A Response instance has following methods:
Response#isSucceeded()Response#getHTTPStatus()Response#getRawBody()Response#getJSONDecodedBody()Response#getHeader($name)Response#getHeaders()
You can use these methods to check the response status and take response body.
Returns a Boolean value. The return value represents whether the request succeeded or not.
Returns the HTTP status code of a response.
Returns the body of the response as raw data (a byte string).
Returns the body that is decoded in JSON. This body is an array.
This method returns a response header string, or null if the response does not have a header of that name.
This method returns all of the response headers as string array.
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:
- Receive webhook from LINE's server.
- Parse request payload by
LINEBot#parseEventRequest($body, $signature). - Iterate parsed events and some react as you like.
The following examples show how webhooks are handled:
For more information, see the official API documents and PHPDoc.
If it's your first time using this library, we recommend taking a look at examples and the PHPDoc of \LINE\LINEBot.
This repository contains two examples of how to use the LINE Messaging API.
A simple sample implementation. This application reacts to text messages that are sent from users.
A full-stack (and slightly complex) sample implementation. This application demonstrates a practical use of the LINE Messaging API.

This library provides PHPDoc to describe how to use the methods. You can generate the documentation using apigen using the following command.
$ make doc
The HTML files are generated in docs/.
Official API documents shows the detail of Messaging API and fundamental usage of SDK.
- Implement
\LINE\LINEBot\HTTPClient - Pass the implementation to the constructor of
\LINE\LINEBot
Please refer CurlHTTPClient that is the default HTTP client implementation.
- PHP 5.5 or later
Please refer HACKING.md.
A very simple SDK (subset) for the LINE Messaging API for PHP. line-bot-sdk-tiny provides a simple interface and functions which makes it a good way to learn how to use the LINE Messaging API.
