Open Checkout

Open the Visa Application experience using the Sherpa SDK.

Please note that we are still adding to this page.

What we are building

1. Add SDK

<script src=”{endUrl}”></script>

<!-- where endURL is defined in the table below -->

Please keep in mind that if your implementation requires a custom endURL we will send it directly to you.

EnvironmentSDK Url

The global function defined below is triggered by any event that happens in the SDK.

function onSherpaEvent(event) { console.log(event); }
{type: "sdkLoaded", data: null}
data: null
type: "sdkLoaded"

The below function creates a widget on the page. This function will change for custom implementations.
