Integrating Verisoul in Web Applications
Integrating Verisoul in web browsers is straightforward and requires minimal code changes. This guide covers everything you need to implement Verisoul’s fraud prevention in your web application.
Installation
Script Tag Installation
Add the Verisoul script to your HTML:
Replace the following parameters:
{env}
: Use eitherprod
orsandbox
{project_id}
: Your project ID, which must match the environment
Installation Options
It is recommended to use the async
or defer
script attributes. If you choose these methods, make sure the Verisoul object is initialized on the window before using it.
Content Security Policy (CSP)
If your application has a Content Security Policy, update it to include the following Verisoul domains:
Usage
Once installed, you can use the SDK to get the current session_id
when you need to make a prediction or reinitialize a session when an account logs out.
session()
Verisoul generates a session_id
to uniquely identify each user session. The session_id
is required when you need to get a risk prediction from the backend API and must be passed from your client to the server.
You can get the current session_id
at any time by calling Verisoul.session()
. The function returns a promise that resolves once Verisoul collects a minimum amount of session information to make a prediction.
Important: Each session_id
expires after 24 hours and cannot be used to call the backend API after expiration. It is recommended to only get a session_id
right before you need to make a server-side request.
Example usage:
reinitialize()
It is recommended that each session_id
only be tied to one account. To avoid problems joining a session to an account, reinitialize the session once an account logs out.
Calling Verisoul.reinitialize()
generates a new session_id
, which ensures that if a user logs out of one account and into a different account, Verisoul will be able to delineate each account’s data cleanly.
Example usage:
account()
This function is intended only for customers piloting Verisoul. Do not use for long term production use or real-time fraud prevention.
The account()
function provides a simplified way to send user account information to Verisoul directly from the client side. While easy to integrate, this method has important limitations:
- Offline analysis only: Data sent via
account()
is only visible in the Verisoul dashboard - No real-time decisions: Unlike the server-side API, this method doesn’t allow your application to receive and act on Verisoul’s risk scores in real-time
- Limited use case: Designed specifically for initial pilots and evaluation purposes
The function accepts the Account Object which is the same object used in the authenticate API, making it easy to transition to the server-side integration later.
Example usage:
For production environments, we strongly recommend implementing the full server-side integration to leverage Verisoul’s real-time fraud prevention capabilities.
