Azure App configuration provides a centralized place for storing the configurations. It provides a configuration explorer where you could add Key/value pair configurations. For more information on this, please refer to the below documentation
https://docs.microsoft.com/en-us/azure/azure-app-configuration/overview
In a BizTalk world, we developers use to store configurations in the SSO database. When I moved to Cloud based development using Logic Apps and Functions, there was nothing available initially for storing configurations in a centralized way. I assume few folks would have utilized the Azure functions application settings to store configurations. But now, we have Azure App Configuration.
At this point of time, we do not have a out of the box connector that can retrieve key/value from App configuration. I checked with the product team on this and say it’s in their roadmap

So, to get around this, I have created an Azure Function that can read from the Azure App configuration using the SDK.
public static class GetAppConfigValues { [FunctionName("GetAppConfigValues")] public static async Task<HttpResponseMessage> Run([HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)]HttpRequestMessage req, TraceWriter log) { log.Info("C# HTTP trigger function processed a request."); // Extract the Config Key from the Request header string appKey = req.Headers.GetValues("AppKey").FirstOrDefault(); // Extract the Connection String from the Function App Settings string connectionString = System.Configuration.ConfigurationManager.AppSettings["AppConfigConnectionString"]; var builder = new ConfigurationBuilder(); builder.AddAzureAppConfiguration(connectionString); var build = builder.Build(); string message = build[appKey.ToString()]; return message == null ? req.CreateResponse(HttpStatusCode.BadRequest, "Azure Configuration Key not found - " + appKey.ToString()) : req.CreateResponse(HttpStatusCode.OK, message); } }
I have installed the nuget package Microsoft.Extensions.Configuration.AzureAppConfiguration
I created an instance of the ConfigurationBuilder and added the app configuration using the connection string. The rest is self explanatory. I can now call the Azure function to read the key/value pair.

I am not sure when the connector will be released. Until then, I will have to use this in our integration projects.
