# Modeling responses

What we need to do with that JSON blob is to generate C# classes from it so that the response can be accessed in Unity.  The simplest way to go about this, even before creating our HTTP operation, is to get a sample of the response from tools such as the [APIGEE Console](https://apigee.com/console/instagram)(defunct) or use [Postman](https://www.getpostman.com/) for your own private APIs.  

* **Step 1: Get the JSON Blob**

Go to the [APIGEE Console for Instagram](https://apigee.com/console/instagram)(defunct) and select OAuth2 from the Authentication dropdown.  Then follow the prompts to allow APIGEE access to your Instagram account.  At this point the Authentication dropdown should say ‘instagram-AuthenticatedUser’.  From the API Method selection pick the method we have been working with: ‘tags/{tag-name}/media/recent’.  Directly in the Request URL you can replace ‘{tag-name}’ with ‘games’ and press Send.  Once a response arrives, click the Snapshot button.  At the Snapshot screen, click the View Raw link and copy all of the JSON data into the clipboard.

* **Step 2: Generate C# Classes**

With the raw JSON text in our clipboard go to [JSONUtils.com](http://jsonutils.com/).  Clear out the ‘JSON Text or URL’ field and paste in your JSON text.  Click Submit.  You just generated a C# representation of the JSON data!

Copy the C# code found in the lower pane and paste it below your HTTP operation.  Notice that the generated class named ‘Example’ is the root class of the response.

*NOTE: Replace all instances of IList to either List or an array.*

**Step 3: Update Operation**

Let’s modify our operation a little and add the following class field.

> `[hg.ApiWebKit.mappers.HttpResponseJsonBody] public Example Response;`

The attribute \[HttpResponseJsonBody] evaluates the returned JSON text and maps it to an instance of the Example class.

It is time to run our operation again.  Attach the debugger and place a breakpoint within the ‘on\_complete’ block.

Below is the response which we can now use within our app.

In the next post we will take a look on how to send and receive data with assets such as BestHTTP, UniWeb, UnityHTTP, etc.
