remote stop, remote start azure-functions

Question

Good afternoon!
There is a working azure-function.
How can I implement remote stop, remote start azure-function in C# (visualstudio).
How to access management (start/stop https://[myname].azurewebsites.net/api/[myfunction]).
As a result, it must be remotely stopped and started in Azure using a program in C#.
Thanks.

Answer 1

@Valdislaf You can leverage the management API endpoints to start and stop the app:
https://learn.microsoft.com/en-us/rest/api/appservice/webapps/start
https://learn.microsoft.com/en-us/rest/api/appservice/webapps/stop
You can use Httpclient to make an API call to the endpoints mentioned in the document. You may need to pass an authorization token for validation , for that please refer to this

Please let me know whether this makes sense. If yes, please don't forget to "accept the answer" and "up-vote" so that it could help others in the community.

/**Azure Active Subscription
Azure CLI Jump or Cloud Shell Jump
1.Open elevated CMD, type az login and press Enter.

>az login

To sign in, use a web browser to open the page https://microsoft.com/devicelogin Jump and enter the code ######### to authenticate.
2.Open in a web browser the page https://microsoft.com/devicelogin, enter the code ######## to authenticate the device on azure.
3.After we authenticate the device to connect Azure we can continue with the next commands and the first is used to set the default subscription.

>az account set  --subscription "########-####-####-####-############"

4.Create Azure Service Principal

>az ad sp create-for-rbac -n "Azure_Service_Principal_Name"

result:
"appId": "e4faxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx2",
"displayName": "Azure_Service_Principal_Name",
"name": "http://Azure_Service_Principal_Name",
"password": "8xxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxx",
"tenant": "d8xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxc34"
