RingCentral exposes communication APIs that allow applications built on different platforms to send messages like SMS, faxes, and calls through the cloud. These APIs can be accessed using RingCentral's SDKs, which make it easy to integrate RingCentral functionality into applications without needing deep knowledge of the underlying API details. The SDKs automatically handle authentication and other tasks like token management. RingCentral provides SDKs for popular languages like Java, PHP, Python, and JavaScript to lower the barrier for developers to integrate RingCentral services.

1. Ring central sdk overview
We seen different RingCentral APIs that are used to send different communication messages over
cloud in different form like SMS, Fax or Call etc. RingCentral exposes all it’s different
communication functionalities via different APIs which can be consumed by different applications
integrated into it and this integration can happened between different platform or application
developed through different programming languages.

2. In simple words, any application, either a standalone running with Java or a web application
created with PHP or JavaScript can use these RingCentral APIs for different functionalities . For
example, A Java application can send SMS to different production support team via these
RingCentral SMS API during a production downtime or outage.

3. RingCentral API uses the OAuth 2.0 protocol to protect all it’s API with authentication and
authorization. RingCentral also provides official SDK (Software development Kit) for different
languages like Java, PHP, Python, JavaScript etc to use their features in application code. It also
has methods to handle the authorization part.

4. The SDKs package of RingCentral APIs has easy-to-use libraries for each
programming language. It has the ability to handle all interaction with the
RingCentral API using existing methods provided in the SDKs, without much
info about lower level details of the API communication itself.
The SDK also provides benefits such as: • It automatically handles token
lifecycle procedures • Re-issues non-authorized requests • Ability to parses
multipart API responses • Provides a broad variety of helper functions to
work with API requests and responses

5. Below are some official and community resources link useful for someone
to start with RingCentral : • PHP SDK is here • For Python programmers
should look here • JavaScript SDK with the JS Developer Guide here • Ruby
SDK can be found here

As we can see there are different SDK, KITs and library already available by
RingCentral to use. It provides a lot of freedom to the developers from
different programming languages and background to use and integrate
these awesome features of RingCentral allowing you much more flexibility
as the APIs are independent to development platform .
