Web SDK Setup

Integrations guide

This page sets out step-by-step instructions for setting up the Web SDK.

WebView manual

Tip
For a better mobile experience and NFC support than WebView integration, we recommend integrating with our App Drop-in.

To integrate the WebSDK via WebView, get a URL to redirect the client to the embedded WebView browser:


Success page

To specify your Success page URL for the SDK to redirect the client to if they successfully complete the workflow, add a redirect parameter to the URL:

Example Success page URL:

https://sandbox.v.fourthline.com/v1/?code=A1B2C3D4&redirect=https://yoursuccesspage.com

Failure page

To specify your Failure page URL for the SDK to redirect the client to if they don't successfully complete the workflow, add a redirectFailure parameter to the URL:

Example Failure page URL:

https://sandbox.v.fourthline.com/v1/?code=A1B2C3D4&redirectFailure=https://yourfailurepage.com

Example with Success and Failure page URLs:

https://sandbox.v.fourthline.com/v1/?code=A1B2C3D4&redirect=https://yoursuccesspage.com&redirectFailure=https://yourfailurepage.com

iOS video playback quality

To ensure video playback quality on iOS and maintain a high conversion rate for document and selfie videos, when you launch the Web SDK in WebView, in your iOS app, set the following parameter in the app to true:

ParameterDescription

Set to true.
