Sharepoint Provider Hosted app with Odata Web API - sharepoint

We have a requirement to build a SharePoint Provider hosted app, which needs to call to a ASP.NET Web API built with Odata. I could't find a exact solution for this. Any help to perform this would be highly approciated

It should be like any other web application as the provider hosted App is totally independent from SharePoint.
IF you are building the app using asp.net, then you can just add a reference to the odata endpoint, ex: http://yourservice/odata/$metadata
Visual Studio will generate a proxy to all entities in the odata service.
If you are building the app using other technology, then deal with the service as a normal REST service and call it using any HTTP client, from browser or a backend.

How to wrap an asp.net WebApi project with azure API management?

I am having a Web API project in asp.net and this project is hosted on Azure web app services .Azure endpoint of the api works . How can i wrap this api under azure api management ?
Current setup
Asp.net web Api project > Hosted in azure web app services
I tried to add the api in API management via blank and open api specification.
I would expect the Azure API Management could connect to my web app service where my asp.net web api project is hosted.
Deploy your Web API to Azure App Service API App instead of App Service Web App. You will be able to import the API's directly from the UI. Here is the doc.
Alternative to Ketan's approach is to configure API manually using "Blank API" option. where you'll need to specify your App's base URL. You will be required later on to create all operations manually.

Azure web and mobile app (shared API)

I'm currently in the planning process for a mobile app I'd like to build, with a companion web app. The Mobile app and the Web app will share common data (for example, users can take a questionnaire in the mobile app or take the same questionnaire on the web app).
I've used Azure a couple of years ago to create and host a web app, but this is my first venture in mobile development. I'm trying to wrap my head around the architecture in Azure for hosting the API.
I've searched high and low, but either can't find a definitive answer to my question, or am not quite understanding what I am reading on the subject.
Basically: Where would my API live in Azure? Would I create a Mobile App in my App Service, which hosts the shared web API? Then create a Web App in the app service, and use something like RESTSharp to access the API from the web app?
AFAIK, Web Apps and Mobile Apps are just different types of Azure App Service Apps which use to host the relevant applications (e.g. WebApps host website,webapi and MobileApps serve as the mobile backend service). Basically, they are the same and the difference between them is the app type and the Quickstart tutorial for them.
For mobile development, you could leverage the relevant SDKs (server-side and client-side) provided by Mobile Apps. You could also deploy your mobile backend application to Azure Web Apps to get the Mobile Functionality.
For Web Apps, you could follow here to build your web application and deploy to web app. For Mobile Apps, you could follow here to build your mobile backend and the tutorials for building your mobile client project.
Basically: Where would my API live in Azure? Would I create a Mobile App in my App Service, which hosts the shared web API? Then create a Web App in the app service, and use something like RESTSharp to access the API from the web app?
AFAIK, for Azure Mobile Apps backend, you could choose Node.js or C#. The relevant server SDKs provide out-of-the-box CRUD operations against the table. I would use the Mobile Apps SDKs to build my backend project and provide the ability to do operations on the specific table and the custom Web API to handle other operations. For your web app, you could use RESTSharp or just leverage the client SDKs provided by Azure Mobile Apps to communicate with your mobile backend endpoint (hosting on a web app or a mobile app).
For C# mobile app backend and mobile client side tutorials, you could follow adrian hall's book here.
For Node.js related mobile backend development, you could follow 30 DAYS OF AZURE MOBILE APPS.

Azure - Making an API App available to a Logic App

I've created a web application API with a swagger interface that I've deployed as an API App to Azure.
When creating a Logic App I can find my API App but whenever I try to use it I get the following error:
Failed to fetch swagger. Ensure you have CORS enabled on the endpoint
and are calling an HTTPS endpoint.
I'm using the default https url for the API definition in the API App:
https://microsoft-SOME-LONG-MS-INTERNAL-ID.azurewebsites.net/swagger/docs/v1
The swagger docs have been provided in my C# web API application through Swashbuckle.
For CORS I've set a single * item.
This didn't seem sufficient for the Logic App to access the API App I then configured Authentication / Authorization for the API App to use Azure Active Directory (express), creating an AD Azure App.
I believe the issue will be one of configuring security which is all pretty new to me in Azure. I'd like to make the API App inaccessible externally, but available to Web Apps and Logic Apps within my Azure subscription.
I've not added any authentication mechanism to the ASP.NET web application itself as I figured the web application would effectively be sitting in a private network on Azure. Perhaps this is a bad assumption and I need to add authentication to allow Azure AD to work?
Any pointers / suggestions?
Turns out I needed to update the Azure SDK for Visual Studio. I had an older version that was deploying a preview Api App which resulted in a "Api app host" type being deployed rather that an "API app" type.
Everything works after the update and I've found some documentation for securing the API App and making it available in the Logic App - https://azure.microsoft.com/en-us/documentation/articles/app-service-logic-custom-hosted-api/

How can i integrate Azure Mobile App win Azure API app

We are building a mobile cross platform solution with Xamarin (Xamarin.Forms).
We developed a backend API in Azure with Azure API Apps.
Now we want to integrate and use Mobile Apps (Mobile Services) but using Azure API Apps we created previously.
I see this BUILD presentation https://channel9.msdn.com/Events/Build/2014/3-623
and the idea i think is to use ApiController and call to Azure API Apps there.
Is this correct? Some sample? How can i do? I must have 2 projects API Apps + Mobile Apps? or I must integrate in one (only one API)?
You could potentially have your mobile clients connect to your API app, but you'll have an easier time if you convert your API App to use the Mobile App backend packages. Another option is to have your Mobile App backend connect to the API app, but that's a lot of hops without much benefit.
For details on these packages, see How to work with the .NET backend server SDK for Azure Mobile Apps.
For a step-by-step tutorial, start with Create a Xamarin.Forms app on Azure Mobile Apps.

Is OWIN/Self-Hosting required for Web API v2 authorization/authentication

I have been trying to learn how to implement authentication and authorization within an ASP.NET Web API v2 project. Does the Web API need to be self-hosted via OWIN before authorization can be implemented or can it still be accomplished when hosting through IIS?
You can host Owin/Web Api in IIS as well.
Remember to install Microsoft.Owin.Host.SystemWeb.
Your config file must be called web.config.
