Is it possible to get azure function URL (at runtime) for Http triggered function app developed in C#.I have implemented a health check for function app.I need to call function URL to check whether the function is healthy or not . I know azure provide services to check FA health but I need to implement as per organization standards. So, Basically it will be a endpoint /healthCheck to get health report.

While I don't understand yet what you are trying to do (and if that is a good idea..) you can infer your function URL through the pre-set env var WEBSITE_HOSTNAME (assuming you are not using a custom domain):
var url = $"https://{Environment.GetEnvironmentVariable("WEBSITE_HOSTNAME")}/api/YOURFUNCTIONNAME";

I do not see a need of getting runtime Azure function app URLs as they remain the same always after creation. On the same lines, you can automate your Function Apps using ARM templates.
And, use the created URLs defined in your endpoint's configuration and use them in your code from the configuration. For example, if you are using App Service, you can save those values in App Settings and read them like below:
var value = Environment.GetEnvironmentVariable("your_key_here");

Yes , I can set function URL in app settings of function app using ARM template . But, for first time when the FA is provisioned , there wont be any function deployed in FA. As per my understanding, I need an separate task (post function deployment) in devops pipeline to set function URL in FA settings.
