Flow Diagram

/The diagram is a typical implementation of our browser SDK.

sessionID and userId is made available to your front-end application (preferable from the backend where required).
Call the BureauAPI.getBureauApiInstance()function with the parameters ( need to call this initiate in onCreate() of application class)
1. sessionId - MANDATORY
2. clientId - MANDATORY
3. environment - MANDATORY - default is production
If you want to collect behavioral signals, then do the following-
1. Call startSubSession to commence the collection of raw behavioral data points
2. Call stopSubSessionto end the collection of raw behavioral data points
3. Ideally, a typical flow would start collecting after the launch of the application and stop collecting after the login or sign-in button is pressed when the user enters the username and password
Call the setters functions for the below mandatory parameters
1. UserID - setUserId - meant to be unique to a user e.g. hashed value of a PAN number or SSN or hash of mobile number
Finally, call the submit function to send the device and behavioral data points for processing
1. Call submitfunction
A callback is received in the SDK upon successful submission of the parameters. The next steps can be taken based on the callback (success/failure)
After receiving a successful callback, invoke the Bureau's backend API /v2/services/behavioural-device-insights to fetch the results of behavioral and device intelligence results such as device fingerprint ID, user similarity score, bot score and so on

Step 1: Initializing an SDK instance

Inside your JavaScript code, initialize SDK with the Session ID, Client ID, User ID, and Environment once the page is loaded. This initializes the data-capturing functionality and collects browser data such as the device's IP address, browser, and operating system.

Example:

window._Fingerprint.init({ 
	sessionId:'f3199e64-cce9-47a2-a79c-67d55314',
	clientId:'3e912115-7890-4238-a123-ab4bb6d82975', 
	userId:'7a68c98e-feb5-4dc0-b9ff-85b469ba97b5',
	environment:'SANDBOX'
})

window._Fingerprint.init({ 
	sessionId:'f3199e64-cce9-47a2-a79c-67d55314',
	clientId:'3e912115-7890-4238-a123-ab4bb6d82975', 
	userId:'7a68c98e-feb5-4dc0-b9ff-85b469ba97b5', 
	environment:'PRODUCTION'
});

Step 2: Initializing behavioral data collection

Start Session

After the SDK initialization, this starts collecting the user behavioral data like keystroke data, click data, motion data, and sensor data. Using these data points, the user similarity behavior, behavioral anomaly score, and bot prediction score are calculated. To train the model on each user, six sessions are needed.

Example:

 window._Fingerprint.startSession();

 window._Fingerprint.startSession();

Stop Session

This stops collecting the behavioral data.

Example:

 window._Fingerprint.stopSession();

 window._Fingerprint.stopSession();

Note: Ideal Flow is to start collecting after the launch of the application and stop collecting after the login or sign-in button is pressed.

Step 3: Submitting an SDK

This submits the collected data to the Bureau. Invoke this method at the end of your page.

window._Fingerprint.onSubmit((response)=>{
  //do something
});

Step 4: Invoke API for Insights

To access insights from users and devices, including device fingerprint, and risk signals, integrating with Bureau's backend API for Device Intelligence insights.

Error Codes

The table below lists a few error codes returned by Bureau's SDKs.

HTTP Error Code	Description	Possible Cause	Recommended Action
420	HTTP exception	Indicates a server-side issue. This can include errors such as: - Rate limiting, server overload, or application error - Firewall or network restrictions - Server-side scripting errors - Third-party services	- Check your server logs to help identify the cause. - Implement rate limiting or load balancing if necessary. - Check firewall rules and network settings to ensure they are not interfering with the connection. - Inspect server logs for any specific error messages or warnings. - Contact the service provider for assistance or look for alternative solutions.
421	Network error	- Too many connections from a single IP address - DNS resolution issues - Load balancer issues - Client-side issues (browser extensions, network configurations)	- Reduce the number of simultaneous connections. Consider using a load balancer. - Try flushing your DNS cache or using a different DNS server. - Check the load balancer's status and logs for any problems. - Try disabling extensions or using a different network connection.
432	A general, unexpected exception or error occurred.	Various reasons such as: - Programming errors - Unexpected input - System failures	1. Review the code for potential errors or logic issues. 2. Check if the input data is valid and meets the expected format. 3. If the error persists, check our SDK documentation or our contact Support Team.
433	The required session ID is missing or empty.	The session ID was not provided or was not passed correctly.	1. Ensure that the session ID is included in the API request and is not empty. 2. Refer to the API documentation for the correct format and usage of the session ID.
434	The eaIV or eaKey is empty. These are essential for decrypting encrypted data.	The required encryption parameters, eaIV (Initialization Vector) and eaKey (Encryption Key) are missing or invalid.	- Verify that the eaIV and eaKey are provided and correct. - Ensure they are generated using a secure method and are not compromised.
