Is it possible to POST form submission to Marketo endpoint directly from HTML form without loading Marketo's forms2.min.js?
I have seen a few old threads suggesting this endpoint still exists but the only method of lead creation that Marketo seems to support in the docs is using the javascript library. We have a version of that working if we have to, but we are hoping that it is still possible to simply post directly to a Marketo endpoint from the HTML form without loading Marketo's javascript library. Does such an endpoint still exist?
An older thread led me to believe that a path like: {our-instance}.marketo.com/index.php/leadCapture/save2&formid={our-form-id}&munchkinId={our-munchkin-id} would be the endpoint we are looking for, but when we try to post a form submission to this endpoint from a form on our site, the request fails and we get this error in console:
"Mixed Content: The page was loaded over HTTPS, but requested an insecure stylesheet 'http://fonts.googleapis.com/css?family=Open+Sans:300'. This request has been blocked; the content must be served over HTTPS."
That leads me to believe we are either hitting the wrong endpoint or not properly authenticated to make this request. But is there a way to do so that doesn't involve loading the javascript? For the record as far as the post-submission redirect page goes, we are using our own hosted on our site and it does not use this font.
Thanks in advance to any insight!
