How To: Implement Chargeback Protection

1. Add the <CoinflowPurchaseProtection> component to every page on your site.
2. Add your merchantId as a property to the <CoinflowPurchaseProtection> component.
3. In every <CoinflowPurchase> component, add the chargebackProtectionData property and input information about each purchase made via Coinflow.

Implement the nSure Mobile SDK

IOS:

1. Drag and drop LocalPods folder from ReactNative > Resources into local IOS folder. Add this line to the podfile “pod ‘nSure’, :path => ‘LocalPods/nSure’” and run pod install
2. Drag and drop NSureSDK.h and NSureSDK.m from ReactNative > Resources into the Xcode workspace. In NSureSDK.h change the conditional import to just “#import <React/RCTBridgeModule.h>”
3. Add dependency AdSupport in the Xcode General tab under Frameworks, Libraries and Embedded Content
4. In the Xcode Build Settings tab add -framework “nSure” to the Other Linker Flags. Follow the remaining steps in the docs as is.
5. Call nsureSDK.sharedInstanceWithAppID to get the deviceId

Android:

1. Create a ‘libs’ folder in the android app and drag and drop Nsure.aar into the folder. Drag and drop NSureSDK.java and NSureSDKPackage.java into the project source (android > app > src > main > java > com > ‘project name’ >)
2. Change the first line in NSureSDK.java and NSureSDKPackage.java from “package com.nsurereactnativesample;” to “package com.<project name>”. Follow the remaining steps in the docs as is.
3. Call nsureSDK.getDeviceId to get the deviceId

Additional Steps:

2. Pass the deviceId in {"<CoinflowPurchase>"} by implementing the following code:

1
import { NativeModules } from 'react-native';
2
var nsure = NativeModules.NSureSDK;
3
var deviceId = "";
4
nsureSDK.sharedInstanceWithAppID("9JBW2RHC7JNJN8ZQ", (nsure, _deviceId) => {
5
  this.deviceId = _deviceId;
6
});

3. In {"<CoinflowPurchase>"} add the chargebackProtectionData property and add information about every purchase that is being made via Coinflow.

SDK Repositories:

Here are the links for the public repositories of the iOS and Android SDKs:

• iOS SDK Repository
• Android SDK Repository

Application ID: 9JBW2RHC7JNJN8ZQ

1. Add the following code to every page on your site:

1
{"<script src=\"https://sdk.nsureapi.com/sdk.js\"> </script>"}
2
<script>
3
  window.nSureAsyncInit = function(deviceId) {
4
    window.nSureSDK.init('9JBW2RHC7JNJN8ZQ');
5
    window.nSureSDK.init({
6
      appId: '9JBW2RHC7JNJN8ZQ', // Remains the same on sandbox and prod
7
      partnerId: 'COINFTEST' //Use COINFTEST on sandbox. This will be assigned on PROD
8
    });
9
  };
10
</script>

📘 This code will allow us to gather information on the user’s device, how they interact with your website, and other info that allows the models to predict the risk of fraud or chargeback for this particular user.

2. To each of your API calls, add the x-device-id header and pass the value which comes as a result of calling window?.nSureSDK?.getDeviceId() on your website.

This deviceId is how the system relates the individual request to the information collected about the user’s device and session from the SDK added above.

3. In the Checkout Endpoint and the Redeem Transaction Endpoint, pass the chargebackProtectionData.

📘 This information provides information about what is being purchased, which allows the AI models to determine the risk of chargeback for this particular purchase.
