Http request from an external site to Zoho Creator

Http request from an external site to Zoho Creator

Hello Experts!

I'm trying to make a http request from an external site to Zoho Creator. I can only write on Javascript.

Please, what is the most direct way to make this request?

I was trying to use the XMLHttpRequest with a getURL (), but it returns "No 'Access-Control-Allow-Origin' header is present on the requested resource." I think CORS is not supported on Creator.

A lot of thanks in advance.

Best regards.

José.
