I am trying to query Watson Discovery News and get some responses in Unity.
First I tried to authenticate my Watson Discovery service through Discovery service APIKey(As described in the "IAM" section in https://github.com/watson-developer-cloud/unity-sdk). My code is exactly the same as the example code in "Query a collection" section in https://cloud.ibm.com/apidocs/discovery/discovery?code=unity#query-a-collection.
Unfortunately, the code always returns due to unsuccessful authentication, thus I cannot get any response. After some debugging, I found out that "tokenData" field in IamAuthenticator.cs(This is part of IBM Unity SDK) is not initialized; this leads to the unsuccessful authentication.
I was able to debug by changing the "yield return" in example code to "return". Otherwise, C# debugger cannot step into the code.
Since I have followed all the steps in IBM documentations, I am not sure how to proceed.
To reproduce the problem, one has to download IBM Unity SDK on https://github.com/watson-developer-cloud/unity-sdk and follow the instructions in README. After setting up, one could replicate the problem using the code below:
var authenticator = new IamAuthenticator(
apikey: "{apikey}"
);
while (!authenticator.CanAuthenticate())
yield return null;
Thanks in advance for any help!
Have you set the URL (SetServiceUrl) to match the location for your service instance? See Service Endpoint in the API reference
I bypassed this problem using Token authentication instead of using APIkey.
If one has the choice of using other SDKs, e.g. Java SDK, please do so. Because Watson Unity SDK is not well supported at the moment.

We're trying to integrate with Google Pay for Passes to add transit tickets to Google Pay, using C# and the "skinny" flow as described here:
"Skinny" JWT variation
We're also using the C# example as provided here: google-pay/passes-rest-samples
The REST calls for transit all succeed and the JWT token is generated, however when trying to add the ticket to Google Pay by using the link "https://pay.google.com/gp/v/save/{jwt_generated}" it just fails with a generic error saying "Something went wrong. Please try again later.". We've tried by just using the link directly, by adding a JS button on a website and even tried loading from a native android application, they all come back with the same error. When using JS button, the error callback returns "SERVICE_ERROR" with no further details. On google console we can see the transit class status as APPROVED.
Any details on what we might be missing would be helpful as it's not clear where the problem is originating from.
There isn't enough information to help you out here. But the best course of action is to request support with the following URL: https://support.google.com/pay/merchants/contact/instore_merchants
The team should be able to look into your specific issues.
I had same issue using passes-rest-samples.
I've missed changing SERVICE_ACCOUNT_EMAIL_ADDRESS in Config.cs, so resolved it by changing it to right service account.
this.SERVICE_ACCOUNT_EMAIL_ADDRESS = "ServiceAccountEmail#developer.gserviceaccount.com"; // CHANGEME
I tried to get the content of the user's profile picture and I found out that I had to call the Beta version because the current version gives the following error message:
"code": "GetUserPhoto",
"message": "The operation is not supported."
So, I tried to switch to Beta, and here is the code that I wrote in C# to do it, but it doesn't work:
Microsoft.Graph 1.6.2
List<QueryOption> options = new List<QueryOption>
{
new QueryOption("$api-version", "beta")
};
var pictureStream = await graphClient.Me.Photo.Content.Request(options).GetAsync();
I got the same error message.
I tried the same request in the Graph Explorer. The 1.0 doesn't work, but Beta works.
The api-version query parameter is used by the Azure AD Graph API. This is a different API than Microsoft Graph. There is a lot of functional overlap (Azure AD Graph is slowly being migrated over to Microsoft Graph) but they use entirely different entities and calling conventions.
In order to call the /beta endpoint using the Microsoft Graph .NET Client Library, you need to change the BaseUrl of the client:
graphClient.BaseUrl = "https://graph.microsoft.com/beta";
var pictureStream = await graphClient.Me.Photo.Content.Request().GetAsync();
Some important notes about the /beta endpoint:
It isn't supported and isn't suitable for production. So don't do that. Or at least don't tell anyone and don't call Support if it stops working. ;-)
The .NET Client uses objects constructed off the production metadata. This means that any entities, actions or properties that were added in /beta don't exist in the models shipped with the SDK.
The .NET Client will ignore any values returned by Microsoft Graph that it doesn't expect to see. So if an endpoint returns a property that wasn't included in the production metadata (see #2), it will simply be ignored.
So long as you're only using a /beta to gain functionality but still expecting /v1.0 results, it should work okay. Photos for example only look at Exchange in v1.0 but look in both Exchange and Active Directory but still return the same result. In theory this means you should be able to swap /beta for /v1.0 without a problem.
I think you are still calling V1 endpoint. In fact, the Beta endpoint is not currently supported in the Microsoft Graph .NET Client Library. More info here.
There is an official beta client for Graph API now:

Long shot, but I'd like to fiddle with ViaGogo API (C# library more precisely). ViaGogo has a well documented public API, documentation is avaliable here.
Problem is, you need to authenticated as it usually happens with this kind of APIs: usually, you find a section of the website, maybe in your profile section, where you can obtain keys, secrets and so on (this happens for example on Facebook or Amazon).
As for ViaGogo, I only found a link that points to a Google Form: this form asks for info about advertising and affiliation on a complete different level of what I need, I won't publish anything read via API. Furthermore, there's no field to leave an e-mail address.
Their C# library seems pretty popular as far as I can tell from downloads from NuGet; I wonder how all these thousands of devs succesfully called that API.
Has anyone succesfully obtained authentication info from ViaGogo?
According to note in registration form, you have to wait for 30 days for their reply.
For more help you can contact them on following contacts:
E-mail: affiliate#viagogo.com
Telephone: +442075532777
Or
http://www.viagogo.com/in/help
There doesn't seem to be any way around this registration according to their website and the api itself -- an appID and password is required. You may try your luck emailing them at Affiliate.Team#viagogo.com -- see this issue on github where the possibility of getting an account via email is discussed: https://github.com/viagogo/developer.viagogo.net/issues/24
I need a little help with the C# example program of Google-Drive...
I used this so-called "tutorial"/"example":
https://developers.google.com/drive/examples/dotnet
And the code from here:
https://code.google.com/p/google-drive-sdk-samples/source/checkout
I uploaded my (only slightly modified) sourcecode here in case anybody doesn't have Mercurial (I didn't have Mercurial and no admin rights to install it either, and Mercurial is the only way to get the sourcecode...):
http://verzend.be/elt0k13enraw/DrEdit.rar.html
I always get
"Ressource cannot be found"
Requested URL: /oauth2callback
I don't find this astonishing, as no oauth2callback controller or handler is implemented...
I tried adding a Controller called oauth2callbackController and redirecting to another action in oauth2callbackController.Index, doing
return new RedirectResult("/about/about");
But that only creates a NULL-reference exception.
So i figured, maybe the wrong controller and redirected to
return new RedirectResult("/drive/Index");
But that only creates an infinite loop of redirect -> allow -> redirect - allow -> etc.
BTW, the config to change the API key + REDIRECT_URI is in
Models\ClientCredentials.cs
Note:
The problem aren't my modifications.
The sample also didn't work unmodified, with the exact same error.
All I did was removing EntityFramwork references, and throwing "Not implemented exception" when a method using entity was called.
Edit:
Additional information:
What I really wanted to do in the first place is to write a console service that exports my database, LZMA-compresses the exported content, encrypts that with OpenPGP, and uploads the database of my server to Google drive every day at 24:00 o'clock, without any user input.
I got export working without a problem, i got the LZMA compression working without a problem, I got the encryption with PGP working without a problem.
After the end of the working day (grrrr), when I was at home, I was even able to download the example-code with the mercurial installed on my Linux-machine at home, and bring it on the windows machine using SMB...
But now I can't get the sample for the Google-drive SDK working...
And moreover, what I really need is an example for a console service/daemon, not a web-application.
When I created the API key, I saw one could create a key for a service, but there is no example on how to write a Google-Drive service (console application), and no useful documentation as well (yea there is a reference, but it's only a reference, IntelliSense provides about the same)...
When configuring your app in the API Access tab of the APIs Console, you had to set the root (/) of your web server as the redirect URI and not /oauth2callback.
Assuming that your app is published at www.example.com, just go back to the APIs Console and set it to www.example.com instead of www.example.com/oauth2callback
As of August 15, Amazon made it compulsory to sign all requests made to their Product Advertising API. I thought I had got everything working just fine but when the 15th finally came around, my web application stopped working and pretty much ever since I have been trying to find out how to sign the SOAP requests.
Amazon has an outdated sample code for signing requests that doesn't appear to work here
Basically, I need to know how to add a signature to the my requests using the most current C# SOAP API and .NET 3.5.
I hope I have given enough details, if I haven't please feel free to ask me to elaborate.
Thank You

UPDATE:
I am using MVC and need to know how to add the Signature to the the ItemLookup or AWSECommerceService object. Is there an attribute that contains the signature value? How does it get attached to the request?
On this page, they say that I must include the Signature and TimeStamp parameters but the intellisense does now show any such attributes.
Check out http://flyingpies.wordpress.com/2009/08/01/17/. It has a walkthrough and a sample visual studio solution using C#, SOAP, WCF on .NET 3.5.
This library automatic sign the requests (Install-Package Nager.AmazonProductAdvertising)
https://www.nuget.org/packages/Nager.AmazonProductAdvertising/
Example:
var authentication = new AmazonAuthentication("accesskey", "secretkey");
var client = new AmazonProductAdvertisingClient(authentication, AmazonEndpoint.US);
var result = await client.SearchItemsAsync("canon eos");
