Synchronous API calls are blocking, meaning they hold up code execution until a response is returned from the server. This can lead to perceived latency or performance lag in an application if not managed properly. In contrast, asynchronous API calls do not block code execution; they allow the program to continue running and handle the response once it’s available, typically through a callback function

 The DCNM API is REST-based, allowing third parties to test and develop application software. It supports a wide range of operations that can also be performed using the DCNM GUI, which uses these REST APIs to render the GUI itself. This means that the same tasks available through the API can be accessed and managed through the graphical user interface, providing flexibility in how network administrators interact with DCNM23.
