BLIK Android Component

This page explains how to add BLIK to your existing Android Components integration.

Requirements

Set up the BLIK Component

1. Import the BLIK Component to your build.gradle file:

   implementation "com.adyen.checkout:blik:<latest-version>"

   For the latest version, refer to our GitHub.

2. Build a client-side configuration of the BLIK Component:

   val blikConfiguration =
     BlikConfiguration.Builder(context, "YOUR_CLIENT_KEY")
     // When you are ready to accept live payments, change the value to one of our live environments.
     .setEnvironment(Environment.TEST)
     .build()

3. Add the Component view to your layout:

   <com.adyen.checkout.blik.BlikView
     android:id="@+id/YOUR_COMPONENT_VIEW_ID"
     .../>

   You will attach the initialized component to this view when collecting payment details.

Collect payment details

Use the client-side Component to collect the phone number from your shopper.

1. Deserialize the /paymentMethods response with the SERIALIZER object:

   val paymentMethodsApiResponse = PaymentMethodsApiResponse.SERIALIZER.deserialize(paymentMethodsResponse)

2. From the result, get the object containing paymentMethods.type: blik.
3. Initialize an instance of the Component. Call PROVIDER.get from the BLIK Component and pass the following:
   • The context (for example, this@YourActivity)
   • The PaymentMethod object (for example, paymentMethod)
   • The BlikConfiguration object:

     val blikComponent = BlikComponent.PROVIDER.get(this@YourActivity, paymentMethod, blikConfiguration)

4. Attach the Component to the view to start getting your shopper's payment details. You need to call attach from the payment method's Component view and pass in:
   • the BlikComponent
   • the context (for example, this@YourActivity): BlikView.attach(blikComponent, this@YourActivity)
     You start receiving updates when the shopper enters their phone number.
5. Check if isValid is true, and when the shopper proceeds to pay, pass the paymentComponentState.data.paymentMethod to your server:

   blikComponent.observe(this@MainActivity) { state ->
     if (state?.isValid == true) {
         //serialize data
         val paymentComponentData = PaymentComponentData.SERIALIZER.serialize(state.data)
         // When the shopper pays, pass the serialized `state.data` to your server to send a /payments request
     }
   }

Handle the await action

Step 1: Deserialize the action object

In your client-side app, deserialize the action object from the /payments response:

val action = Action.SERIALIZER.deserialize(paymentResponse.action)

Step 2: Initialize the Component

1. Before initializing the Component, make sure that you have added the following to your build.gradle file:

   Check the latest version on GitHub.

2. Create a configuration object for the Component, passing your client key:

3. To initialize an instance of the Component, call PROVIDER.get from the Component and pass in the context (for example, this@YourActivity), application class, and the configuration object created in the previous step:

4. From your instance, call handleAction and pass:

   • the context (for example, this@YourActivity)
   • the action object from the deserialized /payments response.

Step 3: Check the payment result

The Component notifies the observer with the actionComponentData object from the data in intent.data. Pass this to your server to make a /payments/details request.

Test and go live

You can test BLIK transactions in the test environment using any 6-digit number that starts with 777 as your blikCode.

You can test different refused payment result scenarios by using the following amounts in your /payments request:

Check the status of BLIK test payments in your Customer Area > Transactions > Payments.

Before you can accept live BLIK payments, add BLIK in your live Customer Area.
