You may on occasion come across an error stating that "This Website doesn't allow access to third party apps".
This is due to the way we serve webpages: We pull the page in using an iframe tag. However, there are ways to prevent a page from being shown in an iframe. If you want your page to be shown on SignCloud, you need to turn those options off.
For example, if your web server sends the X-Frame-Options:SAMEORIGIN tag, it won't serve the page to us when we request it from the iframe, resulting in the above error. Here's a little tool to help you find whether your site has an X-Frame-Options. If so, you may want to remove it or allow *.screen.cloud in the option. More on X-Frame-Options.
If you need additional assistance, please e-mail us, and don't forget to add a link to the web page you're trying to show, so we can test the site for you!
