A RESTful API is an application program interface (API) that uses HTTP requests to GET, PUT, POST and DELETE data. Using a REST API with callbacks (or webhooks) allows for a robust, scalable, asynchronous API model.
Bandwidth provides a REST API for phone number management and line features, and another REST API for sending and receiving phone calls and text messages. Bandwidth also offers a Voice XML model for call control called BXML.
Using Bandwidth’s REST API allows for extreme call control flexibility. Each phone call can be modified in real-time and at any time while the call is active. Calls can be bridged and unbridged as needed to build unique experiences to fit any use-case.
