Automate VM deployment in Azure using Azure Rest API

Hi Everyone,

I need to automate VM deployment in Azure using Rest API. Azure Powershell and CLI are not an option in my project. I won't be using a client application for the same, all the rest API calls needs to be made via coding (preferably python). 

I need to know how can this be achieved. I have already been through the Microsoft documentation on the same but couldn't hit the correct resolution for my queries.

I will require solution to below points.

• Authentication using Azure Rest API calls via code.
• Deployment steps of a resource through Azure Rest API calls from a code.
• Whether keeping the deployment code as an Azure function would work on not
• All the permissions that need to be set in Azure for the deployment
• Prerequisite and how can they be setup to perform the actions

Note : I am new to Azure and hence don't have much knowledge even of a beginner.  

Thanks in advance for any and all the help.
