To enable Sniply on your website, you have two options:
Option B: HTTP Headers
This is a secondary option that requires you to set the X-Frame-Options response header, which will allow anyone to frame your site.
Here's a Mozilla document explaining X-Frame-Options and how to set it in popular server configurations: https://developer.mozilla.org/en-US/docs/Web/HTTP/X-Frame-Options Note that rather than 'SAMEORIGIN', you need to set it to 'ALLOW'.
If you have any issues setting up the X-Frame-Options header, or if you to set the X-Frame-Options header to allow ONLY for Sniply requests, let us know at firstname.lastname@example.org what webserver/framework you're using and we can send over specific instructions/code.
