Thanks for your reply Maarten
So if I'm understanding correctly the embedded api app will allow me to create new pages in the admin section of a store (using all the visual styling already present in the admin area) and that on those new pages I can make calls to my CRM database on my server and have those calls populate values on the new page. I can then edit those values and have them written back to my CRM data base on my server?
Our main developer for this project will want to use PHP and Javascript will the embedded app example work for him?
