Query string/GET request to embed code?

Is it possible to pass any variables that can be read into knacks embed code or any other way to pass the information on load? For instance, I want to embed some knack code on multiple websites and courses and I would like to be able to use a single embed code on all of them and just pass the correct info to display for the page. I supposed I could do the reverse and read the URL via javascript and display the correct info but I would like to know if we can pass variables dynamically into the embed code using a GET request or Query string as it is called
