Microsoft’s Office 365 APIs are a deprecated part of the Microsoft Graph API set – but still underpin the functionality. They are generally of good quality but careful attention should be paid to where your user base will be when building an application as Microsoft routing systems can significantly impact latency. It is also worth noting that by using the legacy O365 APIs you may see faster call times than when using Microsoft Graph APIs.
Microsoft Graph is a unified API that provides access to various data within the Microsoft 365 platform, which includes Office 365, Windows 10, and Enterprise Mobility + Security. These APIs provide access to user data such as mail, calendar, contacts, documents, directory, and more, allowing developers to create rich, integrated applications that leverage this data.
Developers can use the Office 365 APIs to build applications that can read, write, and manipulate data stored in the Microsoft cloud. These APIs expose RESTful endpoints and use standard HTTP protocols, providing a familiar and consistent development experience. Authentication and authorization are handled using Azure Active Directory, which ensures secure access to sensitive data.
Using these APIs, developers can create contextually aware applications that not only interact with Microsoft services, but can also tie into their own services or other third-party services. This flexibility allows developers to build applications that are deeply integrated into the Microsoft ecosystem, yet remain customized to the specific needs of the business or end-user.
Noteworthy is the interoperability of the Office 365 APIs, due to their unified nature under the Microsoft Graph. They provide a way to work across multiple services without having to understand and implement the specific APIs of each service. This significantly simplifies the development process, making the Office 365 APIs a powerful tool for developers aiming to harness the full potential of the Microsoft 365 platform.
