How to implement daemon authorization in MS Azure to use Azure REST API?

Question

API

The idea is this: we want to manage Azure from our web server. Namely, create tasks for the automation service. This is what we will do: https://msdn.microsoft.com/en-us/library/azure/mt6...
In order for Azure to accept some requests from the web server, you must first log in to Azure and receive a token that will later be used in each Azure management command.
Of course, all this should happen, without user intervention.
We acted according to the article https://ahmetalpbalkan.com/blog/azure-rest-api-wit...
But it requires user participation and the presence of a web browser. The demon doesn't have that.
Maybe you don't need to use OAUTH 2.0, but some certificates, or I don't know what else?
Where to dig? Is this even possible?
Thank you!
