Merge's Cookie Policy outlines the use of cookies to enhance user experience on their site, with a link to their Privacy Policy for more information. The company offers a Unified API that allows for hundreds of integrations, and introduces Magic Link, a feature that enables fast and frictionless integration through a shareable URL, requiring zero front-end code. Magic Link can be generated in two ways: through the Merge Dashboard or via an API call, and it expires after a maximum of 7 days. This feature is ideal for providing a seamless user experience, guiding users through authorization, and offering personalized support. Additionally, Merge offers Embedded Link for more control over the integration process, and provides resources such as onboarding docs and a blog with stories and best practices for using their platform.
