How do I generate the API keys for the contact widget? Not

How do I generate the API keys for the contact widget?

Not sure if I am using the widget correctly but I inserted the widget into a page using Themify's Builder and it gave me the widgets properties form to configure the various options. I want to use the CAPTCHA option but its not showing up on my form. I read on one of the support posts that I need to configure the API keys but I dont know how... do I just enter key values I want to use or is there another way of configuring the API keys?

Thanks for your help in advance :slight_smile:
