Previously I discussed how to perform OAuth 1.0a authentication in C#, which is necessary when communicating RESTfully with WooCommerce using Unity. Now I would like to get into more depth in terms of how to do the actual communication with the API using Representational State Transfer (REST) in Unity itself. Note that Unity 5.5 was used when writing this post.
Creating an OAuth signed URL
Since I want to communicate with my WooCommerce REST API, I have to use OAuth 1.0a, which I implemented myself (called OAuth_CSharp library, which can be found here). The OAuth_CSharp library has a public method called GenerateRequestURL(), which takes the URL as a string, the HTTP method (e.g. GET or POST), and optionally a list of custom user parameters. It then returns the OAuth signed URL as a string.
Furthermore, to simplify the usage of the library, I wrote an additional helper function that I attached to my GameObject in question. It takes the URL, parameters and optionally the HTTP method (by default it’s “GET”), and returns the signed URL. This function is as follows:
Ok, now that we can generate our signed URL, lets use it. For this I have two implementations. First using Unity’s built in UnityWebRequest and secondly using BestHTTP, which I suppose in some sense has been made obsolete for REST interactions by UnityWebRequest, but since I own it, I will explain it as well.
Inside the ProcessRequest function, we initialized the UnityWebRequest and then we send the URL for processing. Then, we wait for its response and after getting the response we check if it’s a failure or a success. If there is an error we display the error in our console and if it’s a success we display the response in the console too.

- Creates a UnityWebRequest configured to upload raw data to a remote server via HTTP PUT. This method creates a UnityWebRequest, sets the target URL to the string uri argument and the method to PUT. It also sets the Content-Type header to application/octet-stream. This method attaches a standard DownloadHandlerBuffer to the UnityWebRequest.
- UnityWebRequest provides a modular system for composing HTTP requests and handling HTTP responses. The primary goal of the UnityWebRequest system is to allow Unity games to interact with web browser back-ends.
- I gone through link, I tried examples also. Their it is specified that the form.add method is used to upload the header but it wont work. And I need the post request by using UnityWebRequest. – EKNATH KULKARNI Aug 21 '18 at 5:46.
UnityWebRequest
With the release of Unity 5.3, the Android and iOS backed for UnityWebRequest was finished, allowing easy RESTful interactions built into Unity. To use it simply add using UnityEngine.Networking to the top of your C# file.
Two of the main REST functions you would want to use is GET and POST. Therefore, here are the two basic implementations of each.
GET
It is very easy to perform a GET request, and the best way to do it is using a coroutine. In it’s most basic form the code would look something like this:
However, I would like to have some validation and since this request needs to be processed further in the program, I created two flags: requestFinished and requestErrorOccurred, which are initially set to false. Furthermore, I would like to process the results further (which will be discussed later). We will also now include the OAuth signing of the URL. A point to note, in my experience I also sometimes inexplicably ran into a 401 error, indicating my signature was not valid. However, if I generate a new signature this problem is almost always solved. So I would also like to automatically resend the request if this happens (you could also possibly build in a counter, then make sure this is not an infinite loop). To do this I created two variables lastRequestURL and lastRequestParameters, which simply contains the URL and parameters.
So the new complete code looks like this. If GET was successful a status of 200 will be returned:
The request.downloadHandler.text contains the JSON response text from the server, which we will deserialize into a useable object soon.
POST
For some reason posting is a bit more challenging with UnityWebRequest. You ought to be able to use it with WWWForm using this example on the Unity docs, but it could be that I’m doing something wrong, but I couldn’t manage to get it to work. With the help of these forums (here and here), I managed to get it to work the hard way using the following code segment:
I’m not going to explain much of this, you have the Unity docs for that, but this is all the necessary code to send a request to the server. The response will be in the DownloadHandler object attached to the UnityWebRequest object. And again the response will be a JSON string which can be deserialized and processed further.
Similar to the GET case, here is the full code with validation and output. If POST was successful a status of 201 will be returned:
Best HTTP
Before the days of UnityWebRequest, it was a bit more messy to do REST server request with Unity’s WWW. Best HTTP was a great help to make these requests much simpler. It also has many, many other features which might make it a worthwhile plugin to consider. Especially when dealing with cookies. The plugin is however not cheap with a $60 price tag at time of writing. Here is a brief look at implementing the same GET and POST request using Best HTTP.
GET
Similar to UnityWebRequest this is very simple to do. Just use HTTPRequest and supply the callback function. Here is the example from the included documentation:
And once again the response.DataAsText is a JSON string that we will deserialize later.
POST
This is also very simple, so again the example from the documentation. This time you have to specify the HTTP method.
Similar to the UnityWebRequest examples the Best HTTP GET and POST callback functions can be customized to include all the necessary validation and output generation.
Serializing/Deserializing a JSON string
Deserializing simply means you take the JSON response which is difficult to process in C# and convert it into a simple easy to use representation. It is really up to you how you want to do it. Filezilla free download for mac. A free approach would be to use SimpleJSON, however a much more elegant approach would be to use the JSON .NET plugin for Unity. It is $25 but in terms of time saving and simplicity, you can’t go wrong.
The easies way to set everything up is to create a request, output it to the console, and copy the entire response and paste it into json2csharp. You can then generate the class that JSON .NET requires for serializing/deserializing your JSON text. I would suggest creating a new class, for example Products, and then copy and paste all the sub classes generated by json2csharp into that class. You can then deserialize your JSON string with the following line of code:
Later when you need to serialze an object into a JSON string to POST it to the server you would simply do it with the following line of code:
where newProduct is of type Product.RootObject. Remember that before you can POST it, the JSON string must first be encoded into UTF8 format, as is done in the examples above.
And that’s it! You can now GET and POST JSON strings to a server using Unity.

Unity using JSON from URL - EASY, I don't need all the JSON that's coming from the web URL, I only need the 'rate':'3,394.2033' part. Net's LINQ-to-JSON API (JTokens) you can do this with one line of code: Parse(MyJsonText); // get JSON result objects into a list You can also use the old but gold SimpleJSON from the Unity community. Save the script and head back to Unity to try it out. Keep in mind that sending a request and getting a response from the API may take some time. So make sure you patiently wait. As you can see in the image above, we get a JSON response from the API.
