RingCentral API - Libraries

Use the RingCentral API to manage your business phone system. Their cloud-based phone system interfaces with the Public Switched Telephone Network, allowing businesses and customers to access their phone system via the web or mobile apps. The API is RESTful and uses standard HTTP requests with JSON. The app authenticates with OAuth 2.0. See the extensive documentation at the API home page for detailed instructions on getting started with the RingCentral API.
