An application programming interface or API is a piece of code that allows a developer to integrate a certain functionality into his app or platform. It means you don’t have to build the whole functionality from scratch, saving you a lot of resources and time.
On the other hand, a voice chat SDK is a software development kit that contains all the required components for building a voice chat application. It can contain libraries, APIs, debuggers, compilers, or other components needed for developing a voice chat and calling application. Using a voice chat SDK will help you greatly when developing a voice call platform.
