Estimote Cloud Api's integration in iOS app

i just want to confirm about api’s. Can i add specific action against beacons by using Estimote cloud.
For example i want to show a notification when a beacon detect according to the proximity(Near/Far and Immediate). And i want to add notification content on Estimote cloud. Notifications have tree type of content (image,video and text).
Basically i don’t want to use another server api’s to fetch these notification data.
If this possible please guide me how i can add notification content on estimote cloud ?

Can i add venues on cloud ?
I need your valuable suggestion regarding this.
