SnipCart API Authorization returns 401 Unauthorized

I want to use the V3 SnipCart API to get data about specific orders on my thank you page. I am using C# to do this. I keep getting this error when trying to use the API
System.Net.WebException:'The remote server returned an error: (401)
Unauthorized.'
I have tried to follow their documentation by using only the API key with no password as shown here. Below is my code that I wrote that is giving me the error. I wrote this inside my controller. I get the error as soon as the breakpoint hits this line responseObjGet = (HttpWebResponse)requestObjGet.GetResponse();
//Testing API get data begin
string strurltest = String.Format("https://app.snipcart.com/api/orders/c5541254-r8541-8501-0024-juy85vv002154");
WebRequest requestObjGet = WebRequest.Create(strurltest);
requestObjGet.Credentials = new NetworkCredential("HihiukoJOUBVCTYIiijiGiiYTd6tOiUyTYo", "");
requestObjGet.Method = "GET";
HttpWebResponse responseObjGet = null;
responseObjGet = (HttpWebResponse)requestObjGet.GetResponse(); //401 is triggered here
string strresulttest = null;
using (Stream stream = responseObjGet.GetResponseStream())
{
StreamReader sr = new StreamReader(stream);
strresulttest = sr.ReadToEnd();
sr.Close();
}
Concerns that I have as well are the following:
1.The API key that I entered here is my public api key since I am still in the development and testing phase. I am not sure if this api call will work with the test api key or if I have to use the real secret production key. Any thoughts?
2.I am debugging this off my local machine (localhost:) for now before I deploy these API calls to production to test these changes in prod still with the test api key, could that be a reason for the 401? Since the URL that is trying to get the info is my localhost: url and not my actual domain that I added to SnipCart Dashboard. I was thinking maybe I have to try and hit this from prod environment instead? Any thought?
These are the 2 possibilities that come to mind for me. I am not too savvy on APi's yet so I don't know if my call is missing something.
Summary: All I am trying to do is be able to use the API so that I can load the data I want for an order when users reach my custom thank you page with their token.

Our 401 "Unauthorized" status code is returned when the authentication failed to our API with your Authorization header's value.
Here's the documentation about the auth to our APIs. Make sure to return us a base64 value of your secret API key and the trailing single colon character at the end to respect the Basic Authentication Scheme.
And if you are trying to get data for an order that was placed in live mode then you would need to use the live secret API key.

Error using DropNet

I have the following error when using DropNet library to make connection to DropBox.
Trying to implement it for my CMS and also for my knowledge :)
trying the current documentation of DropNet.
Source:https://github.com/DropNet/DropNet
Current code:
var _client = new DropNetClient(Core.DropBoxAPI, Core.DropBoxKeySecret);
UserLogin login = _client.GetToken();
_client.UserLogin = login;
String Url = _client.BuildAuthorizeUrl();
Produces:
Received Response [Unauthorized] : Expected to see [OK]. The HTTP
response was [{"error": "Unauthorized"}].
Exception: DropNet.Exceptions.DropboxRestException: Received Response
[Unauthorized] : Expected to see [OK]. The HTTP response was
[{"error": "Unauthorized"}].
I want to let the user connect to the Url returned by _client.BuildAuthorizeUrl(); but it even won't let me get to url
and i also have a Key and Secret generated from DropBox.com
if i try to set the method _client.BuildAuthorizeUrl(); as first statement it gives also an error on the DropBox page itselfs.
I tried to find an another post on Stackoverflow but i didn't find any solution so fare.
Its still using the basics of the documentation and it goes wrong.
If you have any ideas that would be nice.
Thanks for the advices.

I was filling the secret the same as the APP key.

Fetching Access token using Auth token from service in C#

I am new to the topic of Oauth and encryption. I need to write a utility where I have authtoken with me and I need to get access token after making a call to the service url say xyzcorp.com. I already have auth token with me I need to use post method to make service call to the url which in turn returns access token. I couldn't find any code snippet which shows how this is done. As I already said I am a newbie into this area, don't have any clue about the implementation in c#. It should be noted that I only have auth token with me.

What C# library are you using? I used Thinktecture.IdentityModel:
https://github.com/thinktecture/Thinktecture.IdentityModel
Here's an example from my OAuth2 Test Client, using IdentityModel:
private static async Task<TokenResponse> SendTokenRequest(string authCode, string redirectUri)
{
var tokenclient = new OAuth2Client(
new Uri(Constant.TokenEndpoint),
Constant.CodeClientId,
Constant.CodeClientSecret);
return await tokenclient.RequestAuthorizationCodeAsync(authCode, redirectUri);
}

PayPal SOAP API - Express Checkout - Error 10002

I'm trying to connect my website to the Paypal Sandbox in order to use the Express Checkout feature. I've used this link as reference but i keep getting the 10002 Error "Security header is not valid".
From the documentation this has to be a invalid credentials problem but if i made the request manually through soapUI it returns "Sucess", if i use the curl command it also works as expected.
Scenario: ASP.NET page with two Web References one to https://www.sandbox.paypal.com/wsdl/PayPalSvc.wsdl and another to https://www.paypalobjects.com/wsdl/PayPalSvc.wsdl, the given credentials are Username, Password and Signature as you can see in the following code snippet:
using CloudShop.com.paypal.sandbox.www;
namespace CloudShop
{
public static PayPalAPIAASoapBinding BuildPayPalWebservice()
{
UserIdPasswordType credentials = new UserIdPasswordType()
{
Username = CloudShopConf.PayPalAPIUsername,
Password = CloudShopConf.PayPalAPIPassword,
Signature = CloudShopConf.PayPalAPISignature
};
PayPalAPIAASoapBinding paypal = new PayPalAPIAASoapBinding();
paypal.RequesterCredentials = new CustomSecurityHeaderType()
{
Credentials = credentials
};
return paypal;
}
Right now i would like to know how to proceed with the debug. What could be wrong?

Some ideas:
Check if you are using the Live-Credentials for the sandbox account.
Are you using https://api-3t.sandbox.paypal.com/2.0/ (especially the -3t part) as the endpoint? You should as you are using Signature authentication.
As usual, you should step through every setting you are using: protocol, API Endpoint, Version, Credentials etc. and compare you're manual SoapUI call with the information stored in you shop configuration.
I also found a blog article on this error that might help resolving this issue.

Real-Time Subscriptions

Good afternoon,
I'm using version 5.4.1 of the Facebook C# SDK. I should note that I am using the source code directly rather than the DLLs (in case this makes any difference).
So the fact that filter attributes are setup is awesome (thank you dev team :).
My issue is occurring during the initial request (before I get to using verifying the GET response from Facebook)
Here is my initial request:
dynamic result = fb.Post(
string.Format("/{0}/subscriptions",
FacebookApplication.Current.AppId),
new Dictionary<string, object>
{
{"object", "user"},
{"fields", "friends"},
{
"callback_url",
"http://localhost:16917/subscription/verify"
},
{
"verify_token",
"77FB802F-1147-48F0-BB0F-E4E9BC1FBCFC"
}
});
I'm finding that an exception is internally being thrown and via Fiddler I'm seeing that the request is never going out. The exception is:
$exception {"(OAuthException) (#15) This method must be called with an app access_token."} System.Exception {Facebook.FacebookOAuthException}
I initially thought this may be related to Facebook.FacebookClient's PrepareRequest method:
if (httpMethod == HttpMethod.Get)
{
// for GET, all parameters goes as querystrings
input = null;
queryString.Append(FacebookUtils.ToJsonQueryString(parameters));
}
else
{
if (parameters.ContainsKey("access_token"))
{
queryString.AppendFormat("access_token={0}", parameters["access_token"]);
parameters.Remove("access_token");
}
}
but commenting out the line parameters.Remove("access_token"); made no difference.
Any help would be greatly appreciated!

What access_token are you using?
Are you using a User's access token, or an App access token?
If you are using an User's access token take a look here http://developers.facebook.com/docs/authentication/#app-login on how to get an App access token.

You will need to use the app access_token.
You can easily create an app access_token using the following constructor.
var fb = new FacebookClient("appid", "appsecret");
dynamic result = fb.Post( .... );
