Is there a REST API support for Azure Network Function Manager, especially for deploying individual network functions to your on-premises environment?
I find unsupported API's but not the supported REST API.
Oh again I found the answer in official Azure document itself. Azure Hybrid Network REST API also support Azure Network Function Manager for deploying individual network functions to your on-premises environment.
