Fourthline's Web SDK smoothly redirects clients from your website to workflows in their mobile browser, hosted by Fourthline on a secure, private subdomain. It takes care of all interaction with the client, collects and uploads the relevant data (e.g. ID document, selfie, geolocation) to Fourthline for case processing. You never handle sensitive personal data.

The SDK leverages our responsive, best-practice UI, and you can customize the appearance to match the look and feel of your brand.

Supported products

The SDK supports the following products:

How it works

The flow is as follows:

Redirect flow

The redirect flow sends the client from your website to the workflow. This functionality is typically hosted by you and embedded in your website.

There are 2 redirect options:

Redirect option	Description
QR code	The client scans a QR code with their mobile device.
SMS	The client receives an SMS containing the workflow URL. • The client enters their (valid) mobile phone number and clicks or taps Send SMS. • While awaiting the SMS, the client can check their mobile phone number is correct. If the countdown reaches zero, they can click or tap Try again to go back and re-enter the phone number. • If the client doesn't receive the SMS, they can re-request it a maximum of 3 times.

Redirect option

Description

QR code

The client scans a QR code with their mobile device.

SMS

The client receives an SMS containing the workflow URL.
• The client enters their (valid) mobile phone number and clicks or taps Send SMS.
• While awaiting the SMS, the client can check their mobile phone number is correct. If the countdown reaches zero, they can click or tap Try again to go back and re-enter the phone number.
• If the client doesn't receive the SMS, they can re-request it a maximum of 3 times.

The QR code and SMS are unique for each SDK session.

Desktop browser

If the client starts on your website in their desktop browser, initialize the Web SDK, display the redirect options, and redirect the client to the workflow URL in their mobile browser.

Mobile browser

If the client starts on your website in their mobile browser, either:

You display the redirect options, and then redirect them to the workflow URL on your subdomain.
Or, if the SDK detects the client's mobile device, instead of displaying the redirect options, it displays a Continue to mobile device screen. This creates a better user experience.

Product flow

The product flow starts, the SDK collects the relevant data, and then uploads it to Fourthline.

At each step, the original browser window displays the client's progress.

Tip

Clients may not know how to take photos with appropriate lighting, background, and framing, which can lead to processing delays or unnecessary rejections.
The Web SDK UI provides clients clear instructions and real-time feedback to optimize image quality, and additional guidance if required.
Fourthline ensures the photos were taken during the workflow, in compliance with art. 41b of the European Banking Authority – Guidelines on the use of Remote Customer Onboarding Solutions under Article 13(1) of Directive (EU) 2015/849.
