In this article, we will discuss basics of Azure API Management to manage our Web API.



In this article, we will discuss all the basics of Azure Management to manage our Web API. Here, we will not discuss about the Azure Management, how it works and how we can create Virtual Machine, Create Cloud App and host Apps with Azure, although our focus will be to stick only to Managing Web APIs using Azure Management.

In this article, we will:

  • Create an ASP.NET WEB API
  • Host/deploy our services to Azure
  • Manage our services using Azure API Management


To work with this article, we need:

  • Visual Studio 2013 or later (you can use community edition)
  • SqlServer 2012 or later (you can use Express edition)
  • Basic knowledge of ORM (we will use FluentNHibernate in our demo app)
  • Basic knowledge of ASP.NET WEB API
  • Basic knowledge of ReSTful services
  • A valid Windows Azure subscription (if you do not have it, get a one month free subscription)

Let's Develop A Simple ASP.NET WEB API

To fulfill the purpose, we need ASP.NET WEB API, which hosts on the server. In this article, we are not going to discuss how to create an ASP.NET WEB API.

To know more about how to create an ASP.NET WEB API, please refer to this article: CRUD Operations with ASP.NET Web API using FluentNHibernate, Repository Pattern.

Host/Deploy Our Services to Azure

I hope you have gone through the article mentioned in the preceeding step. Now, download the demo project if you did not download it yet. Otherwise, you can find the complete source code here: Crudd operations with WEB API.

Let's now deploy our above created services to our Azure server.

  • From Solution Explorer, Right click and Publish

    Publishing to Azure

  • We are deploying/publishing our ASP.NET WEB API as a Azure Website so, we can get a robust endpoint – we will discuss about this in upcoming sessions/articles.
  • And then, click on Publish.


  • After a few minutes, our WEB APIs will be available.
  • Check by browsing URL: Crud With Web API.

    Crud with WEB API

Let's proceed to setup our Azure API Management.


Now, we are ready with our WEB API to host/manage these with AZURE MANAGEMENT. If you do not have any Azure subscription, try a trial one from here: Sign Up Azure Trial.

Create an Instance of API Management

First, we need to create an API Management instance. Follow these step(s):

  • Log into your Azure Management portal from here:
  • If you do not have any subscription, get one from here:
  • Click New, App Services, API Management, Create

    Create instance of API Management

  • In URL textbox, specify a unique sub-domain name to use for the service URL.
  • Choose the desired Subscription and Region for your service instance. After making your selections, click the next button.
  • Enter Organization name and E-mail id

    Image 6

  • API Management service instances are available: Developer, Standard and Premium. By default, new API Management service instances are created using the Developer tier. To select the Standard or Premium tier, check the advanced settings checkbox and select the desired tier on the following screen.

    Image 7

    (P.S.: Premium is not available in promotional and Free/Trial accounts).
  • Finally, click to create.

    Image 8

  • Here, we are on our API MANAGEMENT screen.

    Image 9

  • Click on MANAGE from bottom of your dashboard and we will be on:

    Image 10

  • To create our first API, click APIs from the API Management menu on the left, and then click Add API.

    Image 11

  • Let's discuss what we did in preceeding section(s):

    • We provide a unique name to our API as ‘Demo’ into the Web API Title textbox. Web API Title provides a unique and descriptive name for the API. It is displayed in the developer and management portals.
    • We provide the actual address where our WEB API is hosted, please refer to the above section, where we discussed about the deployment of our WEB API to Azure. into the Web service URL. Web service URL references the HTTP service implementing the API. API management forwards requests to this address.
    • We provide a suffix as ‘demo’ to our API. Web API URL suffix is appended to the base URL for the API management service. Our APIs will share a common base URL and be distinguished by a unique suffix appended after the base.
    • Web API URL scheme determines which protocols can be used to access the API. HTTPs is specified by default.
    (P.S.: Here we selected both HTTP and HTTPs protocols – will discuss about this 
    in coming sections/series of articles)
  • The API section has six tabs.
    • The Summary tab displays basic metrics and information about the API.

      Image 12

    • The Settings tab is used to view and edit the configuration for an API, including authentication credentials for the back-end service.

      Image 13

    • The Operations tab is used to manage the APIs.

      Image 14

    • The Security tab can be used to set Proxy Authentications using Basic and Mutual certificates or can be used to set OAuth 2.0 – we will not discuss this in details.

      Image 15

    • The Issues tab can be used to view issues reported by the developers using our APIs.

      Image 16

    • The Products can be used to create and manage products for our APIs – in this article, we will be not discussing this section.

      Image 17

Add an Operation

Follow these step(s):

  • Go to Operation tab.
  • We did not create anything so, this tab will be empty.
  • Click on ‘Add Operation’ to add new API operation.
  • In our Web APIs, we have the following resources:

    Action HTTP method Relative URI
    Get a list of serverdata GET /api/serverdata
    Get a serverdata by ID GET /api/serverdata/id
    Get serverdata by datatype GET /api/serverdata/type/datatype
    Get serverdata by machine IP GET /api/serverdata/ip/ip
    Create a fresh serverdata POST /api/serverdata
    Update an existing serverdata PUT /api/serverdata/id
    Delete an existing serverdata DELETE /api/serverdata/id
  • Let's add our very first API resource as an operation in API Management portal.

    Image 18

    In the preceeding section, we specified:

    • HTTP verb as a GET – for retrieving the things.
    • URL template – our actual resource of Web API (as mentioned in the above table).
    • For this operation, we did not have any Request parameters so, no need to define any one.
    • Note that we can give parameters as query parameter or Body.
    • Under RESPONSES, we select HTTP STATUS code 200 which is ‘OK’ means when everything will be fine, it will return specified application/json format.

    We are done with our APIs work. We have hosted our Web API with Azure API Management. Now, these are ready to use or to consume by developers. Developers will use Azure API Management developer portal to use/see all APIs related documentations.

    Unfortunately, yet we did not register any user as a developer, let's follow these steps to register our API products.

    (P.S.: we will discuss in coming session – how to setup different products 
    and mange users with Azure API Management).

Get Subscription for Created API Products

To create subscribers, we can do it by invitation and with the use of Administrator portal of API Management.

Image 19

Here, we are using Developer portal where we have already invited/shared our development portal links to our end-users or targeted audience for development.

Discussing API MANAGEMENT Developer Portal

In this section, we are going to discuss all about Developer portal in brief.

Image 20

This will be the default Home page for every developer. Developers can go through the app APIs documentation, your API Blog (if created) and other applications (if you are providing any for any Product).

Since we are not going into details of the Developer Portal, let's sign up as a Subscriber.

  • Click on SIGN IN from Right-Top.
  • From Sign In page (as we have not registered yet), click on Sign up now.

    Image 21

  • Enter all specified details and click on Sign up.

    Image 22

  • You need to verify your email:

    Image 23

  • After verification of your email, log in to developer portal, click on API link.

    Image 24

  • Subscribe to a Product.

    Image 25

  • From Administrator Portal, click Users and approve subscription for user.

    Image 26

    • Click on Demo API from Developer Portal.
    • Here, you will get all APIs listed under Demo.

      Image 27

    • Click on First Get ServerData.

      Image 28

    • Here you can see that our Request URL required a subscription-key which is nothing, just our Primary/Secondary API key, provided by Azure API MANAGEMENT as per subscription.

      Image 29

Testing APIs

We can test our hosted APIs via any external Client or using Console from within API Developer Portal.

  • Click on Open Console from current Get ServerData API.
  • Here, you should need API key, select either Primary or Secondary.

    Image 30

  • After hitting HTTPGET (this is a GET Resource), you will get the related output.

    Image 31

We are done with everything to manage the Web API with Azure API Management.


This article explained the creation of an ASP.NET Web API, hosting to Azure and management using the Azure API Management.

In future sessions/articles, we will explain more about advanced topics/features of Azure API Management.
