@tripleplaypay/react-native v1.1.3

TPP React Native SDK

Getting Started

Install the SDK

npm install @tripleplaypay/react-native

Setup

For assistance setting up the hardware, visit this document.

iOS

To get started with the TPP React Native SDK on iOS, follow these steps: 1. Install the TPP React Native SDK and link the pods:

npx pod-install

2. Open the XCWorkspace file under ios/ in XCode. You can do so from the commandline like this:

open ./ios/MyProject.xcworkspace

3. Add the Bluetooth permission to your app's Info.plist file:

• The app's Info.plist must contain an NSBluetoothAlwaysUsageDescription key with a string value explaining to the user how the app uses this data.
• You can easily configure this from the Info tab. Click on the + button under any of the entries and select Privacy - Bluetooth Always Usage Description and make sure to place an accurate description in the text box next to it.

3. Under the signing and capabilities tab, make sure to set up your Apple account for signing the application.
4. Add the `MagTekSDK.xcframework.

• Under the General tab, Click on the + symbol
• Select the library Workspace > Pods > MagTekSDK.xcframework
• Click add

5. Make sure to build the project in XCode first, this will place the app on your phone. Afterwards you can run the react-native server using:

npx react-native start

Android

If our Android MagTek SDK doesn't resolve, you may need to add our repo to the allprojects section of your android app's gradle file, like so:

allprojects {
    repositories {
        google()
        mavenCentral()
        maven {
            url = uri('https://maven.pkg.github.com/TriplePlayPay/TPP-Android-MagTekSDK')
            credentials {
                username "${GITHUB_USER}"
                password "${GITHUB_TOKEN}"
            }
        }
    }
}

Usage:

1. Import the @tripleplaypay/react-native module in your project:

import {TPPSDKModule} from '@tripleplaypay/react-native';

2. Prior to any usage, initialize the SDK with your publishable key:

TPPSDKModule.initialize('prod-key-example');

or for testing sandbox transactions

TPPSDKModule.initializeSandbox('sandbox-key-example');

3. To initiate a transaction, use the useTransactionUpdates hook to get the startTransaction method and a stateful transactionResult object that updates during each phase of the transaction processing.

   Use the hook inside of a react component so that transactionResult changes will trigger re-render effects:

const {transactionResult, startTransaction} = TPPSDKModule.useTransactionUpdates();

// Start the transaction
startTransaction('10.00');

The message property on transactionResult will begin statefully updating with messages such as: "PRESENT CARD" when it is ready for the user to pay, "APPROVED" if the transaction submitted to TPP servers successfully, or "DECLINED" for other failures.
