-#### Visa SDKs for Account Authentication
-
-Tink Link (a Visa solution) is the front-end SDK for Visa IAV. It is designed to be embedded into your application using one of [Visa’s SDKs](https://docs.us.tink.com/resources/sdk). This guide will focus on using the Web Integration which redirects users to a generated Visa URL to perform the account verification process. If you are building a web application, either for desktop or mobile, use the Web SDK (Exchange Session URL) through:
-
-- [Tink/Visa Link URL](https://docs.us.tink.com/resources/sdk/link-url) (most performant integration option, navigates the entire page from your domain to the Visa domain)
-- [iFrame](https://docs.us.tink.com/resources/sdk/sdk-iframe) (embedded in your domain, Visa domain is not visible)
-
-Note: When referencing the documentation, replace the Tink/Visa Link URL with the external-provider-session URL that you retrieve from the Dwolla API.

 #### Dwolla Node SDK for API Interactions
 
 Throughout this guide, we'll assume you're using the [Dwolla Node SDK](https://developers.dwolla.com/sdks-tools/node) to interact with Dwolla's API endpoints. This SDK simplifies making requests and handling responses for various Dwolla functionalities.
