Implement Revolut Pay - Android

Check the following high-level procedure of implementing Revolut Pay in your Android app. Use the links to jump to the details of each step:

1. Install Android SDK
2. Configure Android SDK
3. Create Revolut Pay button
4. Create Revolut Pay promotional banner

0. Before you start​

Before you start this tutorial, ensure that you have completed the following steps:

• Get started: 1. Apply for a Merchant account
• Get started: 2. Generate the API key

1. Install Android SDK​

1. Since the SDK is hosted on mavenCentral, to fetch the dependency add the following lines to your project level build.gradle:

   allprojects {
       repositories {
           mavenCentral()
       }
   }
   

2. Add the dependency to the module level build.gradle:

   implementation 'com.revolut:revolutpayments:1.0.0'
   implementation 'com.revolut:revolutpay:2.3'
   

3. Sync your project

2. Configure Android SDK​

Initialize the SDK by invoking RevolutPayments.revolutPay.init(environment: RevolutPayEnvironment, returnUri: Uri, merchantPublicKey: String, requestShipping: Boolean, customer: Customer?), where you will need to define:

• environment: either MAIN or SANDBOX. Use the Revolut Business Sandbox environment to test your Merchant account integration before you push the code changes to the production environment.

• returnUri: a URI that represents a deep link used by the Revolut app, to return to your app after the payment is confirmed or rejected. This will greatly improve the customer experience, as it will allow them to return to your app after authorizing the payment.

  The deep link should be registered in manifest to allow opening an activity, if you want to support automatic redirection.

  note

  The returnUri might be based on a custom host-scheme combination that can be defined within your application.

  Here is an example of an activity that can handle returnUri (note that launchMode should be set to singleTop, otherwise it will not be possible to return to your app):

  <activity
      android:name=".MainActivity"
      android:launchMode="singleTop">
      <intent-filter>
          <action android:name="android.intent.action.VIEW" />
          <category android:name="android.intent.category.DEFAULT" />
          <category android:name="android.intent.category.BROWSABLE" />
          <data
              android:host="return_uri_host"
              android:scheme="return_uri_scheme" />
      </intent-filter>
  </activity>
  

• merchantPublicKey: a public key for your merchant account from Revolut console.

• requestShipping: If you want the shipping address and delivery method to be quickly collected from the user through Revolut Pay, pass the requestShipping parameter as true.

  This way, your app can skip the shipping flow during checkout and the user can use existing shipping details stored by Revolut Pay.

  By default, Fast checkout is not enabled.

  caution

  Your backend must support Fast checkout for this functionality to work. For more information, see: Implement Revolut Pay with Fast checkout.

• customer: object containing customer details the merchant already has (name, email, phone number, date of birth).

For more details about the available parameters, see: Parameters: Android.

Now you can integrate the Revolut Pay button into your layout. It can be done either by including it in your .xml file, or by creating it via RevolutPayments.revolutPay.provideButton() method.

3. Create Revolut Pay button​

You can add the Revolut Pay button to your app in the following two ways:

Via adding button from kotlin/java code​

In case you want to create a button from code, you can use the RevolutPayments.revolutPay.provideButton() method, which has the following parameters:

• context - an instance of context used to create a view

• buttonParams - a set of parameters allowing to setup the appearance of the button

  RevolutPayments.revolutPay.provideButton(
      context: Context,
      buttonParams: ButtonParams
  ): RevolutPayButton
  

For more details about the available parameters and button styling, see: Parameters: Android and Revolut Pay button guidelines.

(Optional) 4. Add the Revolut Pay promotional banner widget​

Optionally, you can use the Revolut Pay promotional banner widget to offer rewards to customers who create a new Revolut account after checkout. You can add the widget to your app the following way.

To create the promotional banner, you can use the RevolutPayments.revolutPay.providePromotionalBannerWidget() method, which has the following parameters:

• context - an instance of context used to create a view

• bannerParams - a set of parameters allowing to setup the widget

• themeId - (optional) resource ID of the visual theme to be applied to the banner. If it's not provided, the default theme will be applied.

  RevolutPayments.revolutPay.providePromotionalBannerWidget(
      context: Context,
      bannerParams: BannerParams,
      themeId: Int
  ): RevolutPayButton
  

For more details about the available parameters, see: Parameters: Android

Create a custom theme for the banner​

To apply a customised theme to the banner, create a resource file with the following content:

<style name="RevolutPay_RevolutPayBanner">
    <item name="revolutPay_ColorAccent">#0666EB</item>
    <item name="revolutPay_ColorBackground">#F7F7F7</item>
    <item name="revolutPay_BannerCornerRadius">12dp</item>
    <item name="revolutPay_ComponentCornerRadius">12dp</item>
    <item name="revolutPay_StrokeWidth">0dp</item>
    <item name="revolutPay_StrokeColor">#BBC4CD</item>
</style>

After defining the resource file for your custom theme, reference it in the RevolutPayments.revolutPay.providePromotionalBannerWidget() method:

  RevolutPayments.revolutPay.providePromotionalBannerWidget(
      context: Context,
      params: BannerParams,
      themeId: Int = R.style.RevolutPay_RevolutPayBanner
  ): RevolutPayButton
