PayPal SOAP API - Express Checkout - Error 10002 - c#

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.

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.

How to authenticate with Azure Active Directory programatically in a Connect App for Business Central?

I am attempting to write a connect app that will receive a set of data from an external source and put it inside an instance of microsoft dynamics 365 business central via its APIs. Documentation says there are two ways to do this, using basic authentication and logging in via Azure Active Directory. The former is easy and straightforward to do programmatically, but the documentation makes it very clear that it is not meant for production environments. I'm capable of doing the latter using Postman, but part of the process involves me typing in credentials in a popup window. Since the use case for the final product will be to run without user interaction, this won't do. I want the application to handle the credentials of what will be a service account by itself.
I'm able to modify records using basic authentication, and active directory if I fill out the login form when prompted. I've tried using a library called ADAL, but passing my account's credentials that way led to the following response: {"error":"invalid_request","error_description":"AADSTS90014: The request body must contain the following parameter: 'client_secret or client_assertion.}
I have access to the client secret, but there seems to be no means of passing it via ADAL, that I've found.
I've also tried, at a colleague's recommendation, to log in using the client id and client secret as username and password. The following code is what we ended up with:
RestClient client = new RestClient("https://login.windows.net/[my tenant domain]/oauth2/token?resource=https://api.businesscentral.dynamics.com");
var request = new RestRequest(Method.POST);
request.AddHeader("Content-Type", "application/x-www-form-urlencoded");
request.AddParameter("undefined", "grant_type=%20client_credentials&client_id=%20[my client id]&client_secret=[my client secret]&resource=[my resource]", ParameterType.RequestBody);
string bearerToken = "";
try
{
bearerToken = JsonConvert.DeserializeObject<Dictionary<string, string>>(client.Execute(request).Content)["access_token"];
Console.WriteLine(bearerToken);
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
The code above successfully retrieves a token, but if I use that token I get the following response:
<error xmlns="http://docs.oasis-open.org/odata/ns/metadata"><code>Unauthorized</code><message>The credentials provided are incorrect</message></error>
I've never used Microsoft dynamics 365. But I've validated an user using a local active directory server using C# code.
using System.DirectoryServices.AccountManagement;
public class ActiveDirectoryService {
// The domain url is the url of the active directory server you're trying to validate with.
public bool ValidateWithActiveDirectoryAsync(string domainUrl, string userName, string password) {
using (var context = new PrincipalContext(ContextType.Domain, domainUrl)) {
UserPrincipal UserPrincipal1 = new UserPrincipal(context);
PrincipalSearcher search = new PrincipalSearcher(UserPrincipal1);
if (context.ValidateCredentials(userName, password)) {
return true;
}
}
return false;
}
}
I hope it works for you.

ProviderName returns empty string for google login under .Net Framework 4.0 Webform

I'm trying to authenticate web app using Google sign-in option. I have tried with below options ( as I don't want to use .net 4.0> frameworks)
.Net Framework 4.0
Webforms
Option 1:
OpenAuth.AuthenticationClients.AddGoogle();
This is default option provided under AuthConfig.cs
To get Google login option I have uncommented the above line
Giving Error as Sequence contains no elements. No OpenID endpoint found.
Option 2 :
var client = new GoogleOAuth2Client("clientId", "secretId");
var extraData = new Dictionary<string, string>();
OpenAuth.AuthenticationClients.Add("Google", () => client, extraData);
If I try with above option, when I click on google login, it is taking me to Google Sign in Page, after successful login, while request coming back to the application, OpenAuth.GetProviderNameFromCurrentRequest(); returns empty string. as per the below condition, it is taking me to the login page again. For Facebook and Twitter login, it is returning respective provider name except for the google.
ProviderName = OpenAuth.GetProviderNameFromCurrentRequest();
if (String.IsNullOrEmpty(ProviderName))
{
Response.Redirect(FormsAuthentication.LoginUrl);
}
What is the reason behind it and what is the solution?
If you went with option 2 you need to change RegisterExternalLogin.aspx to the following
{GoogleOAuth2Client.RewriteRequest();
ProviderName = OpenAuth.GetProviderNameFromCurrentRequest();}
This will allow the ProviderName to be found.
You also need to add {using DotNetOpenAuth.GoogleOAuth2;}

Validating Google ID tokens in C#

I need to validate a Google ID token passed from a mobile device at my ASP.NET web api.
Google have some sample code here but it relies on a JWT NuGet package which is .Net 4.5 only (I am using C#/.Net 4.0). Is anyone aware of any samples which do this without these packages or has achieved this themselves? The use of the package makes it very difficult to work out what I need to do without it.
According to this github issue, you can now use GoogleJsonWebSignature.ValidateAsync method to validate a Google-signed JWT. Simply pass the idToken string to the method.
var validPayload = await GoogleJsonWebSignature.ValidateAsync(idToken);
Assert.NotNull(validPayload);
If it is not a valid one, it will return null.
Note that to use this method, you need to install Google.Apis.Auth nuget firsthand.
The challenge is validating the JWT certificate in the ID token. There is currently not a library I'm aware of that can do this that doesn't require .Net 4.5 and until there is a solution for JWT validation in .NET 4.0, there will not be an easy solution.
However, if you have an access token, you can look into performing validation using oauth2.tokeninfo. To perform basic validation using token info, you can do something like the following:
// Use Tokeninfo to validate the user and the client.
var tokeninfo_request = new Oauth2Service().Tokeninfo();
tokeninfo_request.Access_token = _authState.AccessToken;
var tokeninfo = tokeninfo_request.Fetch();
if (userid == tokeninfo.User_id
&& tokeninfo.Issued_to == CLIENT_ID)
{
// Basic validation succeeded
}
else
{
// The credentials did not match.
}
The information returned from the Google OAuth2 API tells you more information about a particular token such as the client id it was issued too as well as its expiration time.
Note You should not be passing around the access token but instead should be doing this check after exchanging a one-time code to retrieve an access token.
ClientId also needs to be passed, which should be set from Google API Console. If only pass TokenId, GoogleJsonWebSignature throws error. This answer is in addition to #edmundpie answer
var settings = new GoogleJsonWebSignature.ValidationSettings()
{
Audience = new List<string>() { "[Placeholder for Client Id].apps.googleusercontent.com" }
};
var validPayload = await GoogleJsonWebSignature.ValidateAsync(model.ExternalTokenId, settings);

IAuthenticationResponse.GetExtension<ClaimsResponse>() always returning null

Update
Thanks to a comment by #IvanL, it turns out that the problem is Google specific. I have since tried other providers and for those everything works as expected. Google just doesn't seem to send claims information. Haven't yet been able to figure out why or what I need to differently to get Google to send it.
A wild stab in the dark says it may be related to the realm being defaulted to http://:/ as I have seen an answer by Andrew Arnott that Google changes the claimed identifier for the same account based on the realm passed with the authentication request.
Another possibly important tidbit of information: unlike many of the examples that can be found around the web for using dotnetopenauth, I am not using a "simple" textbox and composing the openIdIdentifier myself, but I am using the openID selector and that is providing the openIdIdentifier passed to the ValidateAtOpenIdProvider. (As per the Adding OpenID authentication to your ASP.NET MVC 4 application article.)
Question is: why is IAuthenticationResponse.GetExtension() always returning null when using Google as the openId provider, when otherwise all relevant gotcha's with regard to Google (Email requested as required, AXFetchAsSregTransform, etc) have been addressed?
Original
I am struggling with getting DotNetOpenAuth to parse the response returned from the provider. Followed the instructions of Adding OpenID authentication to your ASP.NET MVC 4 application up to the point where the login should be working and a login result in a return to the home page with the user's name (nick name) displayed at the top right. (That is up to "The user should at this point see the following:" just over half way down the article).
I am using Visual Studio Web Developer 2010 Express with C#. DotNetOpenAuth version is 4.0.3.12153 (according to the packages.config, 4.0.3.12163 according to Windows Explorer).
My web.config was modified following the instructions in Activating AXFetchAsSregTransform which was the solution for DotNetOpenId - Open Id get some data
Unfortunately it wasn't enough to get it working for me.
The openid-selector is working fine and resulting in a correct selection of the openid provider. The authentication request is created as follows:
public IAuthenticationRequest ValidateAtOpenIdProvider(string openIdIdentifier)
{
IAuthenticationRequest openIdRequest = openId.CreateRequest(Identifier.Parse(openIdIdentifier));
var fields = new ClaimsRequest()
{
Email = DemandLevel.Require,
FullName = DemandLevel.Require,
Nickname = DemandLevel.Require
};
openIdRequest.AddExtension(fields);
return openIdRequest;
}
This all works. I can login and authorize the page to receive my information, which then results in a call to GetUser:
public OpenIdUser GetUser()
{
OpenIdUser user = null;
IAuthenticationResponse openIdResponse = openId.GetResponse();
if (openIdResponse.IsSuccessful())
{
user = ResponseIntoUser(openIdResponse);
}
return user;
}
openIdResponse.IsSuccessful is implemented as an extension method (see linked article):
return response != null && response.Status == AuthenticationStatus.Authenticated;
and always is successful as the ResponseIntoUser method is entered:
private OpenIdUser ResponseIntoUser(IAuthenticationResponse response)
{
OpenIdUser user = null;
var claimResponseUntrusted = response.GetUntrustedExtension<ClaimsResponse>();
var claimResponse = response.GetExtension<ClaimsResponse>();
// For this to work with the newer/est version of DotNetOpenAuth, make sure web.config
// file contains required settings. See link for more details.
// http://www.dotnetopenauth.net/developers/help/the-axfetchassregtransform-behavior/
if (claimResponse != null)
{
user = new OpenIdUser(claimResponse, response.ClaimedIdentifier);
}
else if (claimResponseUntrusted != null)
{
user = new OpenIdUser(claimResponseUntrusted, response.ClaimedIdentifier);
}
else
{
user = new OpenIdUser("ikke#gmail.com;ikke van ikkenstein;ikke nick;ikkeclaimedid");
}
return user;
}
My version above only differs from the code in the linked article by my addition of the final else block to ensure that I always get the home page with a user name and a logoff link displayed (which helps when trying to do this several times in succession).
I have tried both Google and Yahoo. Both authenticate fine, both return an identity assertion as logged by the WebDev server. However, GetUntrustedExtenstion and GetExtension always return null. I always get to see "ikke nick" from the last else, never the name I actually used to authenticate.
I am at a loss on how to continue to try and get this to work. It probably is some oversight on my part (I am an experienced developer but just started dipping my toes in C# and web front-end development), and I can't see it.
Any and all suggestions on how to proceed / debug this are very much welcome.
Are you using Google as OpenId provider to test your solution against? Because Google has/had the habit of including the Claims only the first time you authenticate the application. So perhaps try using a fresh google account and see if that works?
Sorry for the slow response, doing a big migration at a client this week :-) Glad that this little comment resolved your issue.
