Microsoft has just introduced several new capabilities for developers to leverage its Office 365 platform.

First off, the tech giant has opened up new Office 365 APIs for mail, calendar, contacts, and files.

“These new robust REST-based APIs empower all developers to leverage the more than 400 petabytes of data and popular services across Office 365 in any application,” Microsoft notes. “From a travel reservation app that connects to Office 365 calendars and contacts, to a sales automation app that fully integrates with Office 365 mail and files—the possibilities with Office 365 are endless.”

One of Microsoft’s launch partners for the new Office 365 APIs is the popular multi-platform automation service IFTTT, allowing users to run automated actions or “recipes” connecting different services with Office 365 mail, calendar, contacts, and files. For example, in the recipe shown above, IFTTT is set to text the user if an email is received from Microsoft CEO Satya Nadella.

Microsoft is also releasing new mobile SDKs for native app development. The company is introducing a new SDK for iOS and a new version of its SDK for Android, both of which supplement the Visual Studio SDK. In particular, the iOS SDK supports Objective-C, with support for Apple’s new Swift programming language coming soon.

Finally, Microsoft is now allowing developers to put their apps alongside Outlook, Yammer, or OneDrive in the Office 365 app launcher.

The introduction of the aforementioned developer capabilities follows Microsoft’s announcement that all Office 365 subscribers are now eligible to enjoy unlimited OneDrive storage at no additional charge. An Office 365 subscription starts at $6.99 per month.
