The DocuSign Java library by DocuSign offers a Java REST API that consumes RESTful services related to electronic signature. The access to work with Java has the potential to automate signatures for contracts and documents. At the same time this project provides lines of code, it also displays a redirecting link to study demo services from the official site at http://iodocs.docusign.com/
As the amount of processing power that can be affordably invoked via the cloud continues to increase, applications that were once thought too impractical to build are suddenly quite feasible. A good example of that is AppStream, a new service that Amazon is beta testing that allows graphically and resource-intensive applications to be extended out to any number of devices that previously would not have had the processing capabilities to run them.
Perhaps your most important online network of business contacts is now programmable. LinkedIn launched its API (our LinkedIn API profile), which allows developers to access a user's connections and anyone's profile data, in addition to several other features. Though some are saying "finally," it's clearly not too late for LinkedIn, who aims to be the professional networking platform.
