Integrate hyper SDK to your Kotlin App using Pesaswap-node

​
Requirements

  • Android 6.0 (API level 23) and above
  • Android Gradle Plugin 8.5+
  • Gradle 8.8+
  • AndroidX

​
1. Setup the Server

npm install @Pesaswap-/Pesaswap-node
Follow the Server Setup section.

​
2. Build Checkout Page on Your App

​
2.1 Add the Buildscript Classpath

To start integrating the Pesaswap SDK, add the following classpath to the buildscript block of your project-level build.gradle file: 
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "io.Pesaswap:Pesaswap-gradle-plugin:$latest_version"
    }
}

​
2.2 Add the Plugin

Add the following plugin to the plugins block of your app-level build.gradle file: 
plugins {
    // Apply Pesaswap Plugin
    id 'io.Pesaswap.plugin'
}

​
2.3 Implement the HyperInterface

Next, implement the HyperInterface in your CheckoutActivity. This involves extending FragmentActivity and implementing the HyperInterface: 
class CheckoutActivity : AppCompatActivity(), HyperInterface {
    // ...
}
Note : PaymentSession is designed to work with AndroidX activities. Ensure that your CheckoutActivity extends FragmentActivity or its subclass from the AndroidX library.

​
2.4 Setup the SDK and Fetch a Payment

Set up the SDK using your publishable key. This is essential for initializing a PaymentSession: 
val paymentSession = PaymentSession(applicationContext, "YOUR_PUBLISHABLE_KEY");
Note : PaymentSession needs to be initialized in onCreate method of your FragmentActivity.
Note : For an open-source setup, use the following parameters:
val paymentSession = PaymentSession(applicationContext, "YOUR_PUBLISHABLE_KEY", "YOUR_CUSTOM_BACKEND_URL", "YOUR_CUSTOM_LOG_URL")

​
Fetch a Payment

Request your server to fetch a payment as soon as your view is loaded. Store the client_secret returned by your server. The PaymentSession will use this secret to complete the payment process.

​
3. Complete the Payment on Your App

​
Initialize Payment Session

Initialize the payment session with the client_secret: 
paymentSession.initPaymentSession(paymentIntentClientSecret)

​
Handle Payment Result

Handle the payment result in the completion block. Display appropriate messages to your customer based on the outcome of the payment: 
private fun onPaymentSheetResult(paymentResult: PaymentSheetResult) {
    when (paymentResult) {
        is PaymentSheetResult.Completed -> {
            showToast("Payment complete!")
        }
        is PaymentSheetResult.Canceled -> {
            Log.i(TAG, "Payment canceled!")
        }
        is PaymentSheetResult.Failed -> {
            showAlert("Payment failed", paymentResult.error.localizedMessage)
        }
    }
}
Important : Please retrieve the payment status from the Pesaswap backend to get the terminal status of the payment. Do not rely solely on the status returned by the SDK, as it may not always reflect the final state of the transaction.

​
Present the Payment Page

Create a configuration object to customize the payment sheet and present the payment page: 
val configuration = PaymentSheet.Configuration("Your_app, Inc.")

// Present Payment Page
paymentSession.presentPaymentSheet(configuration, ::onPaymentSheetResult)

​
Final Step

Congratulations! You have successfully integrated the Pesaswap Android SDK into your app. You can now customize the payment sheet to match the look and feel of your app.
