This can be accomplished using Azure.ApplicationModel.Configuration nuget package. In particular, the SetConfigurationSetting method seems to do what you are after.

string connectionString = "<connection_string>";
var client = new ConfigurationClient(connectionString);
ConfigurationSetting setting = client.SetConfigurationSetting("some_key","new_value");

Note: This package is in preview

This works only for Configuration Store I think. Or there is a way to use it with existing web app Application settings? What is connection_string for it then? – arteny Apr 10 '21 at 06:43
@arteny For the connection string, inject `IConfiguration`, then, assuming you've followed the instructions [here](https://learn.microsoft.com/en-us/azure/azure-app-configuration/quickstart-aspnet-core-app?tabs=core5x#connect-to-the-app-configuration-store), you can use `configuration.GetConnectionString("AppConfig")`. – Neo Apr 27 '21 at 19:10

You could use c# to call the REST API Web Apps - Update Application Settings manually.

PUT https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Web/sites/{name}/config/appsettings?api-version=2019-08-01

For more details about how to call Azure REST API in c#, you could refer to this link.

If you want to use c# to do it, you could try with Microsoft.Azure.Management.Fluent package, the below is the sample code, you could have a try.

            string tenantId = "*******";
            string clientSecret = "********";
            string clientId = "********";
            string subscriptionId = "*******";

            var azureCredentials = new AzureCredentials(new
              ServicePrincipalLoginInformation
            {
                       ClientId = clientId,
                       ClientSecret=clientSecret
            }, tenantId, AzureEnvironment.AzureGlobalCloud) ;
            var _azure = Azure
           .Configure()
           .WithLogLevel(HttpLoggingDelegatingHandler.Level.Basic)
           .Authenticate(azureCredentials)
           .WithSubscription(subscriptionId);

            var appResourceId = "/subscriptions/**********/resourcegroups/*******/providers/Microsoft.Web/sites/***"; //Get From WebApp -> Properties -> Resource ID

            var webapp = _azure.WebApps.GetById(appResourceId);

            webapp.Update()
                .WithAppSetting("test", "testvalue")
                .Apply();

Hi George, I have tried your code, it gave me an exception (Operation returned an invalid status code 'Forbidden') , what should I do to solve it — Walid, Feb 13 '20 at 16:31
Did you ever solve you 'Operation returned an invalid status code 'Forbidden' problem? I've run into the same problem — sjokkogutten, Aug 28 '20 at 09:28
Unfortunately this does not work, and as the other two posters have suggested that this produces a 403 forbidden response. — Simon Price, Mar 10 '22 at 11:54

This is an addendum to George Chen's answer.

To avoid the "Operation returned an invalid status code 'Forbidden' exception after calling _azure.WebApps.GetById(appResourceId), you need to ensure the service principal associated with the Azure Credential has contributor access to the subscription the web app is in. For more details refer to https://learn.microsoft.com/en-us/azure/active-directory/develop/howto-create-service-principal-portal.
