SEON JavaScript SDK v6

To successfully utilize this library, you must have a SEON account set up. (https://seon.io)

Installation

You can either use one of our CDNs, or this npm package to load the SDK.

CDN

It is preferred to use one of our CDNs directly, because this way you will always receive the latest version.

<script src="https://cdn.dfsdk.com/js/v6/agent.umd.js"></script>
<!-- or -->
<script src="https://cdn.deviceinf.com/js/v6/agent.umd.js"></script>
<!-- or -->
<script src="https://cdn.seonintelligence.com/js/v6/agent.umd.js"></script>

Then in your JavaScript you can use the window.seon object:

// On page load
window.seon.init();

// Later when the fingerprint is needed
const session = await window.seon.getSession();
// 'session' variable holds the encrypted device fingerprint as a base64 encoded string

For more information about the config options, please visit https://docs.seon.io/api-reference/fraud-api#javascript-agent-v6 . This will give you the collected device info in an encrypted format. You can not decrypt it yourself, you have to send it as the session parameter to SEON's proprietary Fraud API (see https://docs.seon.io/api-reference/fraud-api). The Fraud API will return the device fingerprint in the device_details field.

NPM

Note that with this method you will have to keep the package updated yourself to include our latest features and bugfixes.

npm install @seontechnologies/seon-javascript-sdk
# or
yarn add @seontechnologies/seon-javascript-sdk

Note:

In our package we do not include polyfills but we rely on newer browser features like Promise functionality (namely Promise.allSettled) support. Including polyfills are required for older browser support.

Usage:

import seon from '@seontechnologies/seon-javascript-sdk';
// or
// const seon = require('@seontechnologies/seon-javascript-sdk');

// On page load
seon.init();

// Later when the fingerprint is needed
const session = await seon.getSession();
// 'session' variable holds the encrypted device fingerprint as a base64 encoded string
