Native SDK Integration Steps – Pine Labs Payments

❗️
Security Best Practices:

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. Prerequisites

Available Platform SDKs

Android iOS

Requirements:

Android SDK version 21 (Lollipop) or higher
Android Studio 4.0 or higher
Internet permissions configured in AndroidManifest.xml

1. Requirements:

Requirements

Category	Minimum Supported
iOS Version	`iOS 16.0+`
Xcode Version	`Xcode 15.0+`
Swift Version (SDK)	`Swift 5.x`
Swift Version (App)	`Swift 4+`
Framework Type	`XCFramework`
Architectures	`arm64`

2. Enable Apple Pay Capability in Xcode:

1. Open Your Project in Xcode

Launch Xcode and open your project.
In the Project Navigator (left panel), select your project name.
Under Targets, select your app target.

2. Configure Signing & Capabilities

Click on the Signing & Capabilities tab at the top of the main editor.
Ensure that your Team and Bundle Identifier are properly configured.
Verify that your project uses a valid Apple Developer account (with Merchant ID access).

3. Add the Apple Pay Capability

Click the + Capability button in the top-left corner.
In the popup, search for Apple Pay.
Double-click Apple Pay (or press Enter) to add it.
The Apple Pay capability will now appear under your app’s capabilities list.

4. Configure Merchant IDs

Under the newly added Apple Pay section, locate Merchant IDs.
Click the “+” button to add one.
Select an existing Merchant ID if already created in the Apple Developer Portal.
If not available, choose “Add an Account → Manage Certificates, Identifiers & Profiles” to create a new Merchant ID.
Use a naming convention such as:

bussiness_name.com.yourcompany.app

5. Verify Entitlements

Xcode automatically adds the required entitlements file (if not already present) and enables the following key:

<key>com.apple.developer.in-app-payments</key>
                                    <array>
                                    <string>merchant.com.yourcompany.app</string>
                                    </array>

This ensures your app is authorized to process Apple Pay transactions using the registered Merchant ID(s).

2. Integrate APIs in Your Backend

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

2.1. 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' \

3. SDK Installation & Initialization

Android iOS

3.1. Installation

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

Step 1: Add the SDK Dependency

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

dependencies {
    implementation("com.github.plural-pinelabs:Pinelabs-Android-SDK:1.1.8")
}

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

Step 2: Sync Your Project

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

3.2. Initialization

To initialise the android web SDK, follow the below steps:

Step 1: 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 Redirect 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
)

Step 2: 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.

3.1. Installation

Swift Package Manager Manual Installation

2.1 Add the SDK via Swift Package Manager

Recommended method for easy updates and dependency management

Requirements

Xcode 12.5+ iOS 11.0+

Installation Steps

Open your project in Xcode

Launch Xcode and open your iOS project.

Navigate to Add Packages

Go to the menu:

File → Add Packages…

Enter SDK GitHub URL

In the search bar, paste the SDK GitHub URL https://github.com/plural-pinelabs/Infinity_Checkout_iOS_SDK.

Select Release Tag

Choose the latest Release Tag (e.g., 1.1.1).

Add to App Target

Add the package to your App Target.

Verify Installation

Once added, it should appear in the General tab of your app target. You can also see the package details by clicking on the Package Dependency.

You can also see the package details by clicking on the Package Dependency.

Easy Updates

In case of any new release update, simply select Update Package and it will automatically get the latest build.

2.2 Add the SDK via Manual Method

To add the SDK to your app, import the (SDKFramework).xcframework file to the project using the following steps:

Installation Steps

Download the SDK Framework

You can download the SDK as a (SDKFramework).xcframework file here, which is in a package format that Apple recommends for distributing binary frameworks.

Drag and Drop Framework

Drag and drop the (SDKFramework).xcframework file into your Xcode project in the Project Navigator under the Frameworks section.

Configure Dialog Settings

A dialog box will appear when you drop the framework file into your project.

Ensure that the checkbox labeled "Copy items if needed" is selected. This ensures the framework gets copied into your project directory, making it available for builds.

Complete Installation

Drag and drop the .xcframework in the app.

Copy files to destination.

3.2. Configuration

You need to configure the target to embed the SDK framework properly.

Navigate to the General tab of your target's settings. Add the (SDKFramework).xcframework file under the Frameworks, Libraries, and Embedded Content section.
Ensure you choose Embed & Sign. This ensures the framework is embedded in your app when it's built and signed properly to run on iOS devices.

Note: Once the .xcframework is embedded, you can import the package in the view controller.

Info.plist update: To ensure proper functionality, you must update your app’s Info.plist (Information Property List) file to allow the required connections.

To enable UPI payments, add the necessary URL Schemes in the Info.plist file as shown below:

property-list-view — Figure: Property List View

Without these entries, the SDK won’t be able to navigate to the required UPI payment app.

3.3. Initialization

To initialise the iOS Native SDK, follow the below steps:

Import the SDK into the app.
Create an object of the class PineLabsOnlineSDKManager to initiate the payment function. In your application, you are creating a function that passes the order token received from the create order response to start the payment function of our SDK.

Parameters for startPayment:

from: Pass the context of the current ViewController where the SDK is invoked(generally ‘self’).
orderToken: The token generated from the Create Hosted Checkout API response.
environment: Use .uat for testing (default) or .prod for production.
MerchantCallbackResponse: An instance that sends callback messages to the merchant IOS app. This value remains constant.

Note: You can use a single build and change the environment variable to run the SDK in either UAT or Production. Currently, only two modes are supported: .uat for UAT and .prod for Production.

4. Handle Payment Callbacks

You need to implement call-back methods to handle your payment responses. This will provide the payment status and reason for transaction failures. Based on the reasons for failures, handling can be built at your end. Transaction callbacks can be listened to via overriding methods of EdgeResponseCallback.

Android iOS

Callback Methods

onSuccess() : Triggered when the transaction is successfully completed
onError() : Triggered when an error occurs (network, API failures, etc.)
onCancel() : Triggered when the user cancels the transaction

Callback Methods

onSuccessResponse : Triggered when the transaction is successfully completed
onFailureResponse : Triggered when an error occurs (network, API failures, etc.)
onCancelTxn : Triggered when the user cancels the transaction
onPressedBackButton : Triggered when the user presses the back button

4.1. Implementation Code Samples

public class MerchantCallbackResponse: UIViewController, ResponseCallback {

    public func onFailureResponse(orderID: String, status: String, code: String, message: String) {
        print("Test app response: error occurred")
    }

    public func onSuccessResponse(orderId: String, status: String) {
        print("Test app response: transaction response")
    }

    public func onCancelTxn(orderId: String, code: Int, message: String) {
        print("Test app response: transaction cancelled")
    }

    public func onPressedBackButton(code: Int, message: String) {
        print("Test app response: back pressed")
    }
}

5. Manage Transactions

Track and verify transaction status using Pine Labs APIs. To retrieve the latest status, use the Fetch APIs or subscribe to webhooks for real-time transaction updates.
