Rest API - Translated Forms - CORS issue

I am trying to update the translated forms we have running that use this methodology: https://nation.marketo.com/t5/product-discussions/marketo-form-localization-translations/m-p/53988#M23260. 

 

I updated the submission endpoint, base url, etc to use the REST API information, but I am getting a CORS error.   I am also wondering if I need to reformat the information.  I was able to successfully submit in Postman, but when I added the code to this page: https://sovos.com/it/libreria-dei-contenuti/iva/post-brexit-iva-norme-e-book-proteggere-transfrontaliero-commercio/ I end up with the CORS error in addition to some CSS issues.   

 

I am not sure how to resolve the CORS error, as I am using the URLs provided which are all new and substantially different from both the LP URL and the direct marketo ##--app.marketo.com URL as well.

The REST API is never to be used directly on web pages. The error is expected.

The Marketo REST API (like most such APIs) is for server-to-server or app-to-server communication. Not browser-to-server.

 

And even if you gateway requests from the browser through a back end that in turn communicates with Marketo, you must pay very close attention to per-IP rate limits. Otherwise, you’re letting anonymous people consume your API calls just by interacting with the page.
