8x8 is a company who specializes in services to fit the needs of businesses in the areas of voice, video, mobile, and unified communications. They offer a suite of APIs to couple your needs with the Virtual Contact Center offerings of 8x8.
This API allows clients the ability to interact with external interactive voice response (IVR) systems. This feature is presently embedded in 8x8 IVR Server. Once a request is made to the 8x8 IVR Server, an administrator may configure the IVR script to relay the request to an external server.
Requests are made using HTTPS after being authenticated through an issued "action request" token.
