Sensfrx Extension – Fraud Detection & Analytics for Kodular Apps

Description

Sensfrx is a security and analytics extension designed to help Kodular developers detect and prevent fraudulent activities in their apps. This extension enables features like device fingerprinting, event tracking, location-based actions, and secure transaction management.

With Sensfrx, you can add an extra layer of security to protect your app from fake signups, unauthorized logins, and suspicious transactions.

Blocks Overview

How to Use Sensfrx in Your Kodular App

Prerequisites

Before integrating Sensfrx into your Kodular project, make sure you have:

A Sensfrx Account (Sign up for a free trial and verify your email).
A Property ID and Secret Key (Generated after setup).
The following permissions added to your app:
- Internet: Required for server communication.
- Access Fine Location: Needed for location tracking.

Integration Steps

1. Configure Sensfrx

Use the ConfigureSensfrx block to initialize Sensfrx in your app.

Parameters:
- sandboxMode (boolean): Use true for testing mode, false for production.
- secretKey (String): Your Sensfrx-provided secret key.
Usage:
- This block should be placed in Screen1.Initialize so Sensfrx is ready when your app starts.

2. Generate Encoded Device Fingerprint

Use the GetDeviceFingerprint block to create a unique device fingerprint.

Parameters:
- latitude (double): Device’s current latitude.
- longitude (double): Device’s current longitude.
Usage:
- This fingerprint is useful for authentication and fraud prevention in login, registration, and transaction events.

3. Pass User ID After Login

Use the PassUID block to link user actions to a specific account.

Why use this?
- Ensures that login, transaction, and other activities are linked to a verified user.

4. Retrieve App Details

GetPackageName: Gets your app’s package name.
GetToken: Retrieves a unique authentication token for the session.

These blocks help validate and secure transactions by linking actions to a specific app instance.

5. Track User Actions

TrackClickEvent: Captures screen touch coordinates and gyroscope data. Use this block in every screen where you want to track user interactions.

TrackTransactionEvent: Logs secure transaction details by sending a JSON string with transaction data.
