Please go to this link and follow the steps to setup server for whatsapp verification

Now Let's Proceed Further

Gradle

Add the JitPack repo to your project's build.gradle file:

maven { url 'https: //jitpack.io' }

Add the dependency below to your module's build.gradle file:

dependencies {
	   implementation 'com.github.Piyusinha:WhatsappBasedLogin:v1.0.1'
	}

How to Use

WhatsAppBasedLogin supports both Kotlin and Java projects, so you can reference it by your language.

Create WhatsappLogin with Kotlin DSL

WaVerifySdk.WASdkBuilder(
	context,
	businessnumber,
        socketUrl )
        .callback(whatsappLoginCallback) \\ optional
        .message(message) \\ optional
	.jwtSecretKey(key) \\ required if you are not using our default key
        .build()

Here, whatsappLoginCallback is an interface that you need to define in your app where you would get the success or failure callbacks

Note : Use same businessnumber which you verify on Meta for Developers Portal

Default JWT secret key = "accesstokensecretaccesstokensecr" (lenght must be greater the 32 )

You can trigger the Whatsapp verification flow by calling the following method

GlobalScope.launch {
  WaVerifySdk.getInstance()?.verifyOtpService()
 }

Note: Socket Runs on Background Thread so calling this method require Coroutine Scope.

Implements Callback

val whatsappLoginCallback: WhatsappLoginCallback = object : WhatsappLoginCallback {
  override fun onWhatsAppLoginSuccess(success: WASuccessResponse?) {
      this@MainActivity.runOnUiThread({
          findViewById<TextView>(R.id.textView)?.text = success?.name
      })    
  }
  
  override fun onWhatsAppError(exception: Throwable) {
  
    }
} 

Callback coming from Background thread so it's important to pass it to main thread

Clearing SDK instance (Important)

override fun onDestroy() {
  super.onDestroy()
  WaVerifySdk.getInstance()?.onDestroy()
}

Note: It's important to Destory SDK instance beacause it's close the socket connection.

Check whatsapp present in User's device or not

You can check if the Whatsapp app is present on the user's device or not by using the following method

WaVerifySdk.getInstance().isUsable()
