## Description

#### 한국어 안내

Sendgo(센드고)는 워드프레스와 WooCommerce에서 카카오 알림톡·브랜드메시지와 SMS/LMS/
MMS를 발송할 수 있는 공식 플러그인입니다. Sendgo 계정이 필요하며 메시지 발송은 유료
서비스입니다.

 * 워드프레스 관리자 **설정 > Sendgo**에서 API 인증 정보와 발신 키를 입력합니다.
 * WooCommerce 주문이 **처리 중** 또는 **완료**로 변경되면 구매자의 청구 전화번호로
   알림을 보냅니다. 상태별 템플릿 코드와 대체 문자 내용을 각각 설정할 수 있습니다.
 * 템플릿 코드와 대체 문자 내용이 모두 비어 있는 주문 상태에서는 발송하지 않습니다.
 * 알림톡 템플릿에는 주문 번호가 `#{var1}`로 전달됩니다. 대체 문자 내용에서는 `{
   order_number}`를 사용할 수 있습니다.
 * 한국어 사이트에서는 설정 화면이 자동으로 한국어로 표시됩니다. 번역 파일이 포함되어
   별도 언어팩 설치가 필요하지 않습니다.
 * WooCommerce 없이도 개발자가 플러그인의 클라이언트를 통해 직접 발송할 수 있습니다.

**설치:** 플러그인을 설치·활성화한 뒤 설정 > Sendgo에서 [Sendgo 콘솔](https://sendgo.io)
의 인증 정보를 입력하세요. WordPress.org 설치 ZIP에는 PHP SDK가 포함되어 Composer
를 따로 실행할 필요가 없습니다.

**개인정보 및 외부 서비스:** 발송 전 Access Key와 Secret Key를 Sendgo API로 전송해
인증 토큰을 발급받습니다. 주문 알림 발송 시 구매자 전화번호, 주문 번호, 발신 키,
템플릿 코드 또는 문자 내용이 https://sendgo.io 로 전송됩니다. 직접 발송 시에는 전달한
수신번호와 메시지 내용이 전송됩니다. 설치·활성화만으로는 데이터를 전송하지 않습니다.
인증 정보는 서버의 WordPress 옵션에 저장됩니다.

서비스 제공자: amuz / Sendgo. [이용약관](https://sendgo.io/terms-of-service) · [개인정보처리방침](https://sendgo.io/privacy-policy)

**문제 해결:** 알림이 오지 않으면 주문 상태별 템플릿·대체 문자 설정과 청구 전화번호를
확인하세요. 발송 실패는 WooCommerce 로그의 `sendgo` 항목에 기록되며 주문 처리를 
중단하지 않습니다. 발송이 성공한 주문 상태는 기록하여 같은 상태 알림이 중복 발송되지
않도록 합니다.

#### English

Sendgo (https://sendgo.io) is a Korean business messaging service owned and operated
by amuz,
 the author of this plugin. This is the official Sendgo plugin, and it 
connects your WordPress or WooCommerce site to the Sendgo API.

Korean businesses commonly notify customers over KakaoTalk rather than email. This
plugin
 lets WordPress send those messages, and lets WooCommerce send them automatically
when an order changes status.

Features:

 * Send Kakao Alimtalk and Kakao Brand Message.
 * Send SMS, LMS and MMS.
 * Automatically notify the buyer when a WooCommerce order moves to “processing”
   or “completed”.
 * Fall back to SMS when an Alimtalk message cannot be delivered.
 * Simple admin screen built on the WordPress Settings API.

Kakao Friendtalk (“chingutalk”) was discontinued on 2025-12-31. Friendtalk requests
are now
 automatically delivered as Brand Message by Kakao, so existing configurations
keep working, but new integrations should use Brand Message.

The plugin runs server-side only. Your credentials are stored in the WordPress options
table
 and are never exposed to the front end.

A Sendgo account is required to use this plugin. Message delivery is a paid service;
see the
 Sendgo site for pricing and terms.

### External services

This plugin connects to the Sendgo messaging API (https://sendgo.io) to deliver 
Kakao
 Alimtalk, Kakao Brand Message and SMS/LMS/MMS messages. This is the service
the plugin integrates with; sending messages is not possible without it.

Data is sent to the Sendgo API in the following cases:

 * Before any message is sent, an authentication request containing your Access 
   Key and Secret
    Key is sent to obtain a short-lived API token.
 * When a WooCommerce order changes to “processing” or “completed”, and you have
   configured a
    template code or SMS fallback text for that status: the customer’s
   billing phone number and the order number are sent, along with your sender key
   and the template code or SMS body.
 * When you send a message yourself through the plugin’s client: whatever recipient
   numbers and
    message content you pass to it.

No data is sent when the plugin is merely installed or activated, or when no template
code and
 no SMS fallback text has been configured.

## Installation

 1. Upload the plugin files to the `/wp-content/plugins/sendgo` directory, or install
    the plugin through the WordPress plugins screen.
 2. If you installed from source with Composer, run `composer install` in the plugin
    directory to generate `vendor/autoload.php`. The distributed zip already includes
    it.
 3. Activate the plugin through the “Plugins” screen in WordPress.
 4. Go to Settings > Sendgo and enter your Access Key, Secret Key, sender keys and 
    API version.
 5. If you use WooCommerce, configure the Alimtalk template code and SMS fallback text
    for each order status you want to notify on.

## FAQ

### Can I use this without WooCommerce?

Yes. The Alimtalk and SMS client works without WooCommerce. Only the automatic order

notification feature requires WooCommerce to be active.

### Where do I get my credentials?

From the Sendgo console at https://sendgo.io.

### Why did my customer not receive a notification?

Notifications are only sent for order statuses that have a template code or SMS 
fallback text
 configured, and only when the order has a billing phone number. Delivery
failures are written to the WooCommerce log under the “sendgo” source and never 
interrupt the order flow.

### Will the same notification be sent twice?

No. Each order status is recorded on the order once its notification succeeds, so
re-saving an
 order or a status change triggered by another plugin will not send
a duplicate.

## Changelog

#### 1.5.2

 * WordPress.org 번역 목록의 21개 항목을 한국어 번들에 모두 포함했습니다.
 * 별도 언어팩 설치나 승인 대기 없이 한국어 번역을 사용할 수 있습니다.

#### 1.5.1

 * 한국어 관리자 화면 번역을 번들하고 한국어 사용 안내를 추가했습니다.
 * 공식 Sendgo 로고, 디렉터리 아이콘·배너 및 실제 설정 화면 스크린샷을 추가했습니다.

#### 1.5.0

 * 코어 1.5 연동으로 템플릿 폴더 관리와 폴더 필터를 지원합니다.

#### 1.4.0

 * 계정 API 클라이언트와 코어 1.4 의존성을 추가했습니다.

#### 1.3.1

 * Plugin version headers corrected. 1.3.0 shipped with the header, SENDGO_VERSION
   and
    Stable tag still reading 1.2.4, so WordPress did not offer it as an update.
 * Corrected the note that said identity verification could not be done through 
   the API.
    A mobile sender number can be filed with an identity document attached,
   and the Kakao channel verification code is entered on your own screen.

#### 1.3.0

 * Management API exposed. The core SDK 1.3.0 services — kakaoSenders, noticeTemplates,
   
   brandTemplates, senderRegistration, messageTemplates, kakaoImages, rejectedNumbers
   and webhook — are reachable from Sendgo_Plugin::instance()->client(). Alimtalk
   templates can be registered and submitted for review from inside the plugin.
 * Event webhooks added. Subscribe to sender-number approval, Alimtalk review results,
   
   channel blocking and brand-message targeting results. Verify the signature against
   the raw received bytes (the SDK ships a helper).
 * Kakao image upload added. A brand-message template imageUrl must be a Kakao-hosted
   URL,
    and until now the only way to obtain one was the web console.
 * Opt-out (080) number lookup added, so a store can reconcile its own subscriber
   state.
 * Sender numbers can now be filed through the API with identity documents attached,
   
   so a shop owner no longer has to visit sendgo.io to complete PASS verification.

#### 1.2.4

 * Translated the readme, the plugin header description and all translatable strings
   into
    English so the plugin can be translated on translate.wordpress.org.
 * Documented the external service the plugin connects to and the data sent to it.
 * Corrected the “Contributors” list.
 * Fixed the `url` option being discarded whenever the settings form was saved.

#### 1.2.3

 * Fixed an upload rejection caused by the plugin header having an identical Plugin
   URI and
    Author URI. Plugin URI now points at the repository, Author URI at the
   service homepage.

#### 1.2.2

 * Prepared for wordpress.org distribution. The core SDK (sendgo/php) is bundled
   in vendor/ so
    the plugin installs and runs without Composer.
 * Fixed a version mismatch between the plugin header (1.2.1) and the SENDGO_VERSION
   constant
    (1.1.0).
 * Fixed the plugin silently doing nothing when the core SDK could not be found.
   Installation
    and configuration looked fine while no notification was ever sent;
   the cause is now shown as an admin notice.
 * Updated “Tested up to” to WordPress 7.0 and filled in the changelog.

#### 1.2.1

 * Replaced Friendtalk with Brand Message in the plugin description shown in the
   directory.

#### 1.2.0

 * Reflected the Friendtalk discontinuation (2025-12-31). From 2026-01-01, Friendtalk
   requests
    are automatically delivered as Brand Message (free-form) by Kakao. 
   Added migration notes and a message type mapping table (FT to BT, and so on) 
   to the documentation.
 * Updated the bundled core SDK to sendgo/php 1.2.1.

#### 1.1.0

 * Added short URL API support (via the core SDK).
 * Split templates per order status, fixing an issue where an order moving from 
   processing to
    completed sent the same notification twice and was billed twice.

#### 1.0.0

 * First release: Alimtalk, Friendtalk and SMS sending, plus WooCommerce order notifications.
