Offering Event On The Cloud as a service is very easy. You can either use our URL: http://share.footoomaster.com and direct the customer to it, or hide our url by embedding our site in your website using an iframe (we supply all the info and code on how to add it).
Here is an example that one of our customer did: http://iheartflipbooks.com/share/ You can either do that and embed our design in your website, or do a full customization and brand your own page from scratch. For example, one of our customers did this: http://www.noonah.co.uk/coke/ for Coca Cola. Once you input the code, you can view the branded event on the cloud page where you can further share your digital giveaway.
