Deploying multiple Azure API App Versioning - azure-api-apps

I have a requirement to deploy multiple version of the same API app where the client older application use the existing and the new clients use the new api app which is got more functionality.
Is there a way to achieve this with Azure API Apps?

I have an article that shows how to do Transparent Versioning using API Management in front of API Apps.
The basic idea is that you have a version parameter in a URL and then use the set-backend-service to change which version of the API to access.

Swagger connected to Azure ..now what?

I connected my swagger PetStore api to Azure using swagger Azure API Management integration.
Now that it made it in azure; Where do I implement the actual logic of querying my azure database etc?
Using swagger if I generate a Node server stub I get the following generated. But these are not available if I use API management integration.
In the Backend section I only see Logic Apps and endpoint options. I tried the Logic App stuff but it seems I need 50 logic apps if I have api that large...Am I missing something?
Maybe you need to use SwaggerHub.
The Swagger UI you are currently using belongs to the community version and should not support direct integration. Assuming there are 100 api interfaces, you need to add 100 times in azure apim.

Creating an custom API using existing API

I am trying to set up a custom API for my application. This is a corporate application that I installed in my environment. The application comes with it's own out-of-the-box REST API, but I'm looking for a way to create my own custom API leveraging the existing one. The reason I want to create a custom API is because of all the customizations that have been made to the underlying database. I'm looking at using Node.js and the Express application framework to create the custom API, but all the use cases I've seen for this are for creating new APIs from scratch. I guess my question would be, how can I integrate my existing web services API into a Node.js (Express) set up. My existing web services API runs an Apache Tomcat web service. This publishes the existing web service endpoints in a format like this:
http://://?fields=,...
I'm looking for tips, pointers or something that can point me in the right direction. If there are any alternate (better) solutions available aside from Node.js (Express) I am open to exploring that as well.

Create API using Azure API management

I built a web application using react and node , and also i want to build a mobile app , so i'm trying to build REST API to manage the database . I heard about the Azure API management and trying to using it but couldn't find any tutorial that relevant with javascript
Does Anyone know good tutorial to refer??
Azure API Management is not intended to create API, it is intended to act as a proxy, to harden your API against attacks from outside. You should be using WebApp or ApiApp to create your API.
I assume that you want to build Mobile App back-end on Azure with node.js SDK.
About how to use the Azure Mobile Apps Node.js SDK, you could refer to the official documentation here: https://learn.microsoft.com/en-us/azure/app-service-mobile/app-service-mobile-node-backend-how-to-use-server-sdk.
Also, you could take the following complete series tutorial on the Node.js SDK as reference: https://shellmonger.com/30-days-of-azure-mobile-apps-the-table-of-contents/.
Any further concern or my misunderstanding, please feel free to let me know.

How to use my own API instead of using mobile API in Azure

is there any way to publish my API in azure mobile service API instead of using its own. I want just to know it, because assume I have a backup server in amazon and as you know I don't have access to azure sdk in there and it means technically I cant use the API anywhere outside the azure.
Azure mobile services is actually based on the .Net web api in their C# flavor and on node.js on the Javascript side. You could surely write an API using those technology and have the same behavior. You will gain the fact of being more portable, however you will lose some of the preconfigured stuff from Mobile services.
If you are using .NET, please check this to see how to build a Web api! http://www.asp.net/web-api.
If you are using Javascript, here is where you should start : https://nodejs.org/
Both tech are quite easy to learn and super powerfull, have fun! When your API is built, you could just publish them as an azure Web APP (http://azure.microsoft.com/en-us/services/app-service/web/) or an Azure API (https://azure.microsoft.com/en-us/services/app-service/api/) instead of the mobile App
Hope it helps, if you have more questions, please ask!
You can create and publish your own custom APIs in azure mobile service. You could even access in via azure mobile service sdk in client by using "InvokeApiAsync<>()" method.
https://msdn.microsoft.com/en-us/library/windows/apps/xaml/dn614130.aspx
If you want to access the api via fidder/httpclient than AZM SDK, pass the mobile service key in HTTP header as Name:'x-zumo-application' value:'application key from portal'

What is the difference between an API App and a Web App?

I've been reading a few tutorials now on deploying Web Apps and API Apps to Azure. However, I am still a little unsure as to why you would use one over another.
I can create a new .NET solution with API controllers and deploy this as a Web App, so why would I specifically require an API App? Are these optimized specifically for ASP.NET Web API, where as Web Apps are for delivering HTML?
Updating the answer to current state of Azure,
App Services now replaces all Mobile, Api and Web Apps flavors as a single app framework with all the functionality rolled over to make things more accessible across application types. Currently all of Web, Mobile and Api Apps are collectively called App Services. We still offer customer to be able to create a Mobile App and a Web App in the gallery but that is basically resolve into an App Service App.
https://azure.microsoft.com/en-us/documentation/articles/app-service-api-apps-why-best-platform/
Features for Mobile work for Web App as well such as Easy Tables and Easy API. And features for API apps like API Cors and API definitions now work on web apps as well. A customer can host a single web app to act as any mobile service or an api with all the features offered through the app services.
We also have a new service in preview particularly targeting API Apps by offering a management experience for your APIs, Basically you can control the generate try API pages, gather execution analytics, throttle and much more. Check out the feature blog to learn more about the Azure API Management Features. And yes you can host the APIs as a App Service App and hook things up with API Management.
https://azure.microsoft.com/en-us/documentation/articles/api-management-get-started/
There was a point in time when there were differences between the different app service types, but that is no longer true. The documentation now states:
The only difference between the three app types (API, web, mobile) is the name and icon used for them in the Azure portal.
So it no longer matters which app service type you choose to deploy to (unless you care what the icon looks like).
UPDATE
Function apps are now the exception. Creating a function app changes the user interface in the portal. The underlying web app, however, is no different. Setting an app setting named FUNCTIONS_EXTENSION_VERSION = ~1 turns any web app into a function app (minus the user interface in the portal).
There are many minor difference between Web API and API Apps, but the very notable and key differences are
Native Swagger implementation - When you create API App in Visual studio, swagger reference comes by default. Swagger provide very developer friendly features for API consumers to Interact with your API thru Swagger UI. Also Swagger based API's provides client SDK generation (both .Net based client and Javascript based client) which makes easy to call API's just like regular method call.
Note: Swagger implementation on regular Web API is possible manually.
Ability to publish your API Apps into Azure Market Place. Azure Market Place is the public repository for all API Apps that can be consumed freely or by charge.
this 15 minute video from Channel 9 gives an excellent overview about Api Apps.
To supplement Greg's answer, Here's an even more recent article describing the differences.
To sum up:
"The key features of API Apps – authentication, CORS and API metadata – have moved directly into App Service. With this change, the features are available across Web, Mobile and API Apps. In fact, all three share the same Microsoft.Web/sites resource type in Resource Manager."
And here's another important note:
"If your API is already deployed as a Web App or Mobile App, you do not have to redeploy your app to take advantage of the new features."
This can depend on what you are trying to do, but you would use a Web API when you are creating a service. ASP.Net Web API is a framework for building HTTP services that can be consumed by a broad range of clients. This allows you to build it not only for a web app, but have it open to connect to Android apps, IOS apps, web apps, Windows 8 apps, WPF apps etc..
So if you need a Web Service but you don't need SOAP then you can use Web API.
Here my comments:
API app:
Used for specific functionallity. Triggering that functionality from an URL.
Can be used to use with GET, POST, PUT, DELETE.
Can receive parameters at BODY (Json).
Response with valid status code (fail, sucess.)
Web APP: An application deployed with multiple functionallity, for example
a catalog for create, update and delete customers or to create a complete ERP.
Function APP: Is very similar to API app,
Used for specific functionallity. Triggering that functionality from an URL.
Can be used to use with GET, POST, PUT, DELETE.
Can receive parameters at BODY (Json).
Response with valid status code (fail, sucess.)
Actually you can deploy your aspnet webapi on Azure WebApp and a self host on Worker Roles.
On WebApp (former Azure websites), it will be deployed on IIS, so you can take advantage of IIS features.
