Whatsapp business api SDK, written in java. This SDK implements the Official [Whatsapp Cloud API](https://developers.facebook.com/docs/whatsapp/cloud-api) and [WhatsApp Business Management API](https://developers.facebook.com/docs/whatsapp/business-management-api) and [Engagelab Whatsapp API](https://jiguang-docs.yuque.com/te6n14/whatsapp.engagelab/birhgucglgdgqc6c). These allows you to:
- manage your WhatsApp Business Account assets, such as message templates and phone numbers;
- send messages to your contacts, such as simple text messages, messages with buttons, video, images, sticker...
- upload, delete and retrieve media files.
- receive webhooks events

The WhatsApp Business API allows medium and large businesses to communicate with their customers at scale. Using the API, businesses can build systems that connect thousands of customers with agents or bots, enabling both programmatic and manual communication. Additionally, you can integrate the API with numerous backend systems, such as CRM and marketing platforms.

This sdk implements whatsapp business cloud api version v16.0. [See api changelog](https://developers.facebook.com/docs/whatsapp/business-platform/changelog)

This sdk implements engagelab whatsapp API version v1.

## :hammer_and_wrench: Installation

:warning: this library is compatible with **java 1.8+**.

### Maven

**1. Add the [JitPack](https://jitpack.io/#harmonyzhang/whatsapp-business-java-sdk) repository to your build file:**

```xml
<repositories>
	<repository>
		<id>jitpack.io</id>
		<url>https://jitpack.io</url>
	</repository>
</repositories>
```

**2. Add the following Maven dependency to your project's `pom.xml`:**

```xml
<dependency>
  <groupId>com.github.harmonyzhang</groupId>
  <artifactId>whatsapp-business-java-sdk</artifactId>
  <version>v1.0.1</version>
</dependency> 
```

### Gradle:

**1. Add it in your root build.gradle at the end of repositories:**

```gradle
allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}
```

**2. Add the dependency**

```gradle
dependencies {

## :eyes: Overview

There are two client classes that can be used to interact with the API:

1. [`WhatsappBusinessCloudApi`](https://github.com/harmonyzhang/whatsapp-business-java-sdk/blob/main/src/main/java/com/whatsapp/api/impl/WhatsappBusinessCloudApi.java), a synchronous/blocking [WhatsApp Business Platform Cloud API](https://developers.facebook.com/docs/whatsapp/cloud-api) client;
> Send and receive messages using a cloud-hosted version of the WhatsApp Business Platform. The Cloud API allows you to implement WhatsApp Business APIs without the cost of hosting of your own servers and also allows you to more easily scale your business messaging.

```java
 WhatsappApiFactory factory = WhatsappApiFactory.newInstance();

WhatsappBusinessCloudApi whatsappBusinessCloudApi = factory.newBusinessCloudApi(TestConstants.TOKEN);
```

2. [`WhatsappBusinessManagementApi`](https://github.com/harmonyzhang/whatsapp-business-java-sdk/blob/main/src/main/java/com/whatsapp/api/impl/WhatsappBusinessManagementApi.java), a synchronous/blocking [WhatsApp Business Management API](https://developers.facebook.com/docs/whatsapp/business-management-api) client;
>The WhatsApp Business Management API allows you to programmatically manage your WhatsApp Business Account assets, such as message templates and phone numbers.

```java
WhatsappApiFactory factory = WhatsappApiFactory.newInstance();

WhatsappBusinessManagementApi whatsappBusinessCloudApi = factory.newBusinessManagementApi(TestConstants.TOKEN);
 ```

3. [`WhatsappEngagelabApi`](https://github.com/harmonyzhang/whatsapp-business-java-sdk/blob/main/src/main/java/com/whatsapp/api/impl/WhatsappEngagelabApi.java), a synchronous/blocking [Engagelab Whatsapp API](https://jiguang-docs.yuque.com/te6n14/whatsapp.engagelab/birhgucglgdgqc6c) client;
>需要有个极光账号并开通whatsapp服务.

```java
WhatsappApiFactory factory = WhatsappApiFactory.newInstance();

WhatsappEngagelabApi whatsappEngagelabApi = factory.newEngagelabApi(TestConstants.ENGAGELAB_DEV_KEY,TestConstants.ENGAGELAB_DEV_SECRET);
 ```

These can be instantiated through the corresponding factory method of [`WhatsappApiFactory`](https://github.com/harmonyzhang/whatsapp-business-java-sdk/blob/main/src/main/java/com/whatsapp/api/WhatsappApiFactory.java), by passing the token, which can be created following the instructions at [whatsapp](https://developers.facebook.com/docs/whatsapp/cloud-api/get-started).

## :arrow_down: WebHooks
Webhooks are triggered when a customer performs an action or the status for a message a business sends a customer changes.

WebHook objects are mapped on [**WebHookEvent class**](https://github.com/harmonyzhang/whatsapp-business-java-sdk/blob/main/src/main/java/com/whatsapp/api/domain/webhook/WebHookEvent.java)

See [Whatsapp api documentation](https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks) for more details.
**Example:**

```java
//payload = the webhook payload json sent by Whatsapp
//using WebHook.constructEvent() to deserialize event
WebHookEvent event = WebHook.constructEvent(payload);
```
See an example [here](https://github.com/harmonyzhang/whatsapp-business-java-sdk/tree/main/src/test/java/com/whatsapp/api/examples/WebHookExample.java)

You get a webhooks notification:

1- When a customer performs an action

- Sends a text message to the business
- Sends an image, video, audio, document, or sticker to the business
- Sends contact information to the business
- Sends location information to the business
- Clicks a reply button set up by the business
- Clicks a call-to-actions button on an Ad that Clicks to WhatsApp
- Clicks an item on a business' list
- Updates their profile information such as their phone number
- Asks for information about a specific product
- Orders products being sold by the business

2- When the status for a message received by a business changes (includes pricing information)

- delivered
- read
- sent

3- When WhatsApp Business Management API updates:

- Message Template Updates
- Phone Number Updates
- WABA Updates

## :paperclip: Media

You can use 4 different endpoints to manage your media:

- Upload media.
- Retrieve the URL for a specific media.
- Delete a specific media.
- Download media from a media URL.

**See the examples:**

#### [Uploading media](https://github.com/harmonyzhang/whatsapp-business-java-sdk/tree/main/src/test/java/com/whatsapp/api/test/examples/UploadMediaExample.java)

WhatsappBusinessCloudApi whatsappBusinessCloudApi = factory.newBusinessCloudApi(TestConstants.TOKEN);

var fileName = "starwars.png";

byte[] fileContent = Files.readAllBytes(Paths.get("src/test/resources/" + fileName));

var response = whatsappBusinessCloudApi.uploadMedia(TestConstants.PHONE_NUMBER_ID, fileName, FileType.PNG, fileContent);

System.out.println(response);
```
