Embedded Overlay

Parallel provides a “Serverless” option for partners with existing websites. By adding a few lines of JavaScript to an existing web page, you can provide a flow embedded right on your site. You can then make API calls directly from frontend JavaScript without any backend server code necessary.

This option can be as easy as a quick copy and paste into an existing web page, so it is one of the fastest ways to integrate with Parallel.


You can see a live example for demo purposes on our test site Here’s a screenshot of the overlay “on top” of the SafeHarbor example site:
