Yes. Our REST API can initiate calls, buy phone numbers, send SMS messages, get detailed information about account activity, create conference calls, and much more! Experience with REST is useful when developing with Avaya OneCloud CPaaS, but it is not required. We do our best to provide as much information needed for working with our REST API in our documentation.
