Infinity Checkout Android Native SDK Integration

The Android Native SDK integration involves the following steps below:

📘
Note:

Ensure you store your Client ID and Secret in your Backend securely.

Integrate our APIs on your backend system.

We strictly recommend not to call our APIs from the frontend.

Failure to adhere to the above guidelines may result in legal implications. In such cases, you will be held responsible for any damage or loss arising from non-compliance.

1. [Prerequisite] Integrate APIs in Your Backend

Start a payment by triggering the payment flow. To start a payment, follow the below steps:

1.1. Generate Auth Token

Integrate our Generate Token API in your backend servers to generate the auth token. Use the token generated to authenticate Pine Labs Online APIs.

Below are the sample requests and response for the Generate Token API.

curl --location 'https://pluraluat.v2.pinepg.in/api/auth/v1/token' \
--header 'accept: application/json' \
--header 'content-type: application/json' \
--header 'Request-Timestamp: 2024-07-09T07:57:08.022Z' \
--header 'Request-ID: c17ce30f-f88e-4f81-ada1-c3b4909ed235' \

2. Installation

Follow the steps below to add the Express SDK to your Android application and initialize it using the token from the Order Creation API.

2.1. Add the SDK Dependency

Add the dependency to your app-level build.gradle:

dependencies {
    implementation 'com.github.pinelabs.express:1.0.0'
}

Alternatively, you can declare it through catalog styling using libs.versions.toml.

build-gradle-image — Figure: ADD SDK Dependency

2.2. Sync Your Project

Sync your project with Gradle to download the SDK and make it available in your build.

2.3. Initialize and Launch the SDK

Use the method below to start the SDK and pass the token received from the Create Order API.

ExpressSDKInitializer().initializeSDK(
    this@MainActivity,
    "${tokenEt.text}", // Replace with the actual token
    object : ExpressSDKCallback {

        override fun onError(
            errorCode: String?,
            errorMessage: String?,
            errorDescription: String?
        ) {
            Toast.makeText(
                this@MainActivity,
                "Error: $errorCode, $errorMessage, $errorDescription",
                Toast.LENGTH_LONG
            ).show()
            Log.e("ExpressSDK", "Error: $errorCode, $errorMessage, $errorDescription")
        }

        override fun onSuccess(
            responseCode: String?,
            responseMessage: String?,
            responseDescription: String?
        ) {
            Toast.makeText(
                this@MainActivity,
                "Success: $responseCode, $responseMessage, $responseDescription",
                Toast.LENGTH_LONG
            ).show()
            Log.i("ExpressSDK", "Success: $responseCode, $responseMessage, $responseDescription")
        }

        override fun onCancel(
            responseCode: String?,
            responseMessage: String?,
            responseDescription: String?
        ) {
            Toast.makeText(
                this@MainActivity,
                "Cancelled: $responseCode, $responseMessage, $responseDescription",
                Toast.LENGTH_LONG
            ).show()
            Log.d("ExpressSDK", "Cancelled: $responseCode, $responseMessage, $responseDescription")
        }
    },
    true // Set to false for PROD, true for UAT
)

initialize-start-sdk-image — Figure: Initialize SDK

2.4. Configure the Environment

Configure the runInSandBox flag based on the environment:

UAT (Testing):
Set runInSandBox = true
Production (Live):
Set runInSandBox = false

📘
Note:

Always validate the full flow in UAT before switching to Production.

2.5. Handle SDK Callbacks

The SDK triggers three callbacks via ExpressSDKCallback. Implement all three to manage the payment flow effectively:

1. onError

Triggered when an error occurs, such as network or API failures.
Provides:

errorCode
errorMessage
errorDescription

2. onSuccess

Triggered when the transaction is successfully completed.

3. onCancel

Triggered when you customer cancels the transaction.

3. Manage Transactions

To get the status of the transaction made from your application, you can use our Fetch APIs to know the real time status.

3.1. Get Order by Order ID

Use this API to know the real time status of the transaction made on your application. Refer to our Get Order by Order ID API documentation to learn more.

3.2. Webhooks

You can configure the webhook events to know the status of your transactions. Refer to our Webhooks documentation to learn more.
