Is api call carrying data?

hi, thanks for the plugin. I followed the blog post, mentioned in a previous reply for how to use it. I have my api and site keys in plugin settings saved, civicrm set ok (checked with internal api explorer, it works) however the contact form in wordpress can’t reach api and thus can’t create a contact. my webserver tells me that the api call was shown a 403 error (which I’m not getting if I use the keys as parameters when trying) and it’s reasonable as the 403 getting url has no parameters. I’ve tried to see if the POST method carries, but there is no network traffic when sending the form in WordPress… I can’t see what I’m missing. How can I check which POST request is sent by the plugin to my civicrm?
