Need suggestion on with MS Graph Rest API url - microsoft-graph-api

I kinda need to suggestion on picking the accurate MSGraph url between below 2 urls.
https://graph.microsoft.com/v1.0/users/{EmailAddress}.
https://graph.windows.net/{TenantID}/users?$filter=userPrincipalName%20eq%20'{EmailAddress}'&api-version=1.6
More details on my situation:
I need to resolve the UserName and ObjectID from MS Graph Rest api using EmailAddress. I have 100s of EmailAddress that I need to resolve UserName and ObjectID for. I was using below which is working fine for most of the time. But lastnight i realized it is not returning valid response for 2 users.
var httpClient = new HttpClient
{
BaseAddress = new Uri("https://graph.microsoft.com/")
};
string URI = $"/v1.0/users/{EmailAddress}";
Then I realized, below rest API url is retuning accurate response for the missing users as comared to above url
var httpClient = new HttpClient
{
BaseAddress = new Uri("https://graph.windows.net/")
};
string URI = $"/{TenantID}/users?$filter=userPrincipalName%20eq%20'{EmailAddress}'&api-version=1.6";

Simple POST from website to external web api fails

I have an asp .net MVC-page
Im trying to connect to Eventbrite:s api
Simply put, it requires you to send client id to one url, using HttpGET and HttpPOST the result and some more info to another url.
The GET goes fine and I get the required (auth)"code". When I try to make the POST to the second url I get
"Socket Exception: An existing connection was forcibly closed by the
remote host"
I can POST to the second url, using Postman and the info from the GET-request it works ok, I get the auth token just fine.
This is the code Im using
var parameters = new Dictionary<string,string>();
parameters.Add("code", pCode);
parameters.Add("client_secret", CLIENT_SECRET);
parameters.Add("client_id", CLIENT_APP_KEY);
parameters.Add("grant_type", "authorization_code");
using (var client = new HttpClient())
{
var req = new HttpRequestMessage(HttpMethod.Post, pUrl) { Content = new FormUrlEncodedContent(parameters) };
var response = client.SendAsync(req).Result;
return response.Content.ReadAsStringAsync().Result;
}
I have a vague memory of a similar problem when publishing to Azure. Since I have to register my app with a public return url I cant look at the request with fiddler.
My site is running https.
I have also tested adding the below line (from some googling)
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
But then I get 404-error...
I have also tested this (with same result)
using (var client = new HttpClient())
{
var response = client.PostAsync(pUrl, content).Result;
authToken = response.Content.ReadAsStringAsync().Result;
}
Ive tested getting the auth code and and running the POST from local machine, same result...
I have contacted eventbrite developer support to see if they can help me as well...
This POST must contain the following urlencoded data, along with a Content-type: application/x-www-form-urlencoded header.
Since your content-type is application/x-www-form-urlencoded you'll need to encode the POST body, especially if it contains characters like & which have special meaning in a form.
Then use the following function to post your data:
using (var httpClient = new HttpClient())
{
using (var content = new FormUrlEncodedContent(parameters))
{
content.Headers.Clear();
content.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
HttpResponseMessage response = await httpClient.PostAsync(url, content);
return await response.Content.ReadAsAsync<TResult>();
}
}
The error message you provided means the remote side closed the connection, the causes are:
·You are sending malformed data to the application.
·The network link between the client and server is going down for some reason.
·You have triggered a bug in the third-party application that caused it to crash.
·The third-party application has exhausted system resources.
·Set ServicePointManager.SecurityProtocol = ServicePointManager.SecurityProtocol | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
For more details, you could refer to this case.
Changed OAuth access token URL from
https://www.eventbrite.com/oauth/token/
to (as specified)
https://www.eventbrite.com/oauth/token
(ie without trailing slash). Now it works

Call Graph API from MVC App

SUMMARY UPDATE:
I got a sample working today thanks to the many good replies. Thanks all. My primary goal was to get current user information (ME) without using secret key. First I just used the secret key from the App Reg and this will authenticate the App and not the user. This does of course not work when calling ME. My next finding was if you want the users token, you still need the App Reg token, and then you request the users token. This requires less permissions on the App Reg, but requires to request two tokens. I ended up skipping ME and just requesting information for a specified user (through the APp Reg permissions):
$"https://graph.microsoft.com/v1.0/users/{email}/$select=companyName"
Both both approaches should be viable. I updated code below with working sample.
I am trying to do a very simple call to graph API to get companyName from current user. Found some samples but they seemed to be very complicated. The MVC app is authenticated trough an Application Registration in AAD.
I guess the application registration needs to be authorized to access Graph API. Or is more needed here? Getting company name should be fairly simple:
https://graph.microsoft.com/v1.0/me?$select=companyName
Does anyone have a snippet for calling the graph API, my best bet would be you need to extract a bearer token from the controller? ALl help is appreciated.
Working snippet:
public async Task<ActionResult> Index()
{
string clientId = "xxx";
string clientSecret = "xxx";
var email = User.Identity.Name;
AuthenticationContext authContext = new AuthenticationContext("https://login.windows.net/xxx.onmicrosoft.com/oauth2/token");
ClientCredential creds = new ClientCredential(clientId, clientSecret);
AuthenticationResult authResult = await authContext.AcquireTokenAsync("https://graph.microsoft.com/", creds);
HttpClient http = new HttpClient();
string url = $"https://graph.microsoft.com/v1.0/users/{email}/$select=companyName";
//url = "https://graph.windows.net/xxx.onmicrosoft.com/users?api-version=1.6";
// Append the access token for the Graph API to the Authorization header of the request by using the Bearer scheme.
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, url);
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", authResult.AccessToken);
HttpResponseMessage response = await http.SendAsync(request);
var json = response.Content.ReadAsStringAsync();
return View();
}
To add one last item, here is a link to an MVC sample on Git that uses an MVC application to send email. It illustrates how to call the MS Graph API to get various pieces of information. Keep in mind, if you are using an application only scenario, ME will not work, the sample illustrates how to obtain a delegated token for a user and use that toke to do work:
https://github.com/microsoftgraph/aspnet-connect-rest-sample
If I am reading this code snippet correctly, You are requesting a application only token for the Graph.Microsoft.Com resource, then attempting to use that toke with this URI:
url = "https://graph.windows.net/thomaseg.onmicrosoft.com/users?api-version=1.6"
This will not work because you are mixing resources, AAD Graph and MS Graph. The ME endpoint does not make since in this scenario because you are using the application only flow. This flow does not support the ME endpoint. ME is designed for use with a delegated token. the ME endpoint represents the signed in user, since and application is not a user, ME is meaningless.
You will need to target the user specifically:
https://graph.microsoft.com/v1.0/Users/[UPN or ID of user]?$select=companyName
Should work if your application has been granted the appropriate permission scopes.

OAuth1 Authentication in RestSharp for Twitter API GET and POST methods

Using Postman I'm successfully able to query and create tailored audiences using the Twitter API, using Postman's OAuth 1.0 Authorization. However when trying to do the same with RestSharp I get an Unauthorized error.
"UNAUTHORIZED_ACCESS" - "This request is not properly authenticated".
My GET request authenticates fine, but the POST request fails.
_twitterRestClient = new RestClient("https://ads-api.twitter.com/1")
{
Authenticator = OAuth1Authenticator.ForProtectedResource(ConsumerKey, ConsumerSecret, AccessToken, AccessSecret)
};
var restRequest1 = new RestRequest(string.Format("/accounts/{0}/tailored_audiences", TwitterAccountId), Method.GET);
//this works and gives me a list of my tailored audiences
var response1 = _twitterRestClient.Execute(restRequest1);
var restRequest2 = new RestRequest(string.Format("/accounts/{0}/tailored_audiences?name=SampleAudience2&list_type=EMAIL", TwitterAccountId), Method.POST);
// this results in an "Unauthorized" status code , and the message {\"code\":\"UNAUTHORIZED_ACCESS\",\"message\":\"This request is not properly authenticated\"}
var response2 = _twitterRestClient.Execute(restRequest2);
Turns out this is due to a quirk in RestSharp OAuth1 implementation. I think its related to this issue - https://www.bountysource.com/issues/30416961-oauth1-not-specifing-parameter-type . Part of creating an OAuth1 signature involves gathering all the parameters in the request and other details and then hashing it all. It looks like when the HTTP Method is a POST, then RestSharp is not expecting parameters in the querystring (which makes sense), its expecting them in the post body. Anyhow if you add parameters explicitly then they are picked up and the OAuth1 signing works. (Turns out the twitter API works if these params are in the post body, so I didn't need to explicitly add them to the query string). Updated code that now works:
_twitterRestClient = new RestClient("https://ads-api.twitter.com/1")
{
Authenticator = OAuth1Authenticator.ForProtectedResource(ConsumerKey, ConsumerSecret, AccessToken, AccessSecret)
};
var restRequest1 = new RestRequest(string.Format("/accounts/{0}/tailored_audiences", TwitterAccountId), Method.GET);
var response1 = _twitterRestClient.Execute(restRequest1);
var restRequest2 = new RestRequest(string.Format("/accounts/{0}/tailored_audiences", TwitterAccountId), Method.POST);
restRequest2.AddParameter("name", "SampleAudience2");
restRequest2.AddParameter("list_type", "EMAIL");
var response2 = _twitterRestClient.Execute(restRequest2);

How to Access twitter from Salesforce

I am struggling to get this done, I need to connect to twitter rest Api 1.1 to get user details, time line etc.
What I came across is:
I have a Twitter App with access token ,secrete etc.
Now how to use all that access token etc to send (GET or POST) request to Twitter from Salesforce. How to set header or how to authenticate request.
A tutorial would be very help full all I could find was tutorials for php etc I need it for "salesforce"
Note: I don't want to use a external lib
You should be able to do this directly from Apex using the HTTP REST library. Here is the first Google result for "salesforce apex twitter integration" with this sample code from Navatar_DbSup:
VF CODE:
<apex:inputTextarea id="tweetInput" onkeyup="return maxLength();" onKeyPress="return maxLength();" value="{!newTweet}" rows="2" cols="73"/>
<apex:commandButton id="tweetBtn" style="height:35px;" value="Tweet" action="{!postTweet}" />
Controller code:
*** post tweets into twitter*/
public String newTweet{get;set;}
public Void postTweet()
{
Http h = new Http();
HttpRequest req = new HttpRequest();
Method = 'POST';
req.setMethod(Method);
req.setEndpoint('https://api.twitter.com/1/statuses/update.xml');
newTweet = newTweet.replace('%','%25').replace('&','%26').replace('#','%40').replace(';','%3B').replace('?','%3F').replace('/','%2F').replace(':','%3A').replace('#','%23').replace('=','%3D').replace('+','%2B').replace('$','%24').replace(',','%2C').replace(' ','%20').replace('<','%3C').replace('>','%3E').replace('{','%7B').replace('}','%7D').replace('[','%5B').replace(']','%5D').replace('`','%60').replace('|','%7C').replace('\\','%5C').replace('^','%5E').replace('"','%22').replace('\'','%27').replace('!','%21').replace('*','%2A').replace('(','%28').replace(')','%29').replace('~','%7F');
req.setBody('status='+newTweet);
req.setHeader('Content-Type','application/x-www-form-urlencoded');
OAuth oa = new OAuth();
if(!oa.setService())
{
message=oa.message;
}
oa.sign(req);
HttpResponse res = h.send(req);
system.debug('&&&&&&&&&&&&&&&&7' + res.getBody());
PostTweetbody = res.getBody() + '___' + message;
newTweet = '';
}

QuickBooks Online querying with filter returns 401 everytime

I've had success creating objects with POST and Content-Type application/xml
I've also had success querying using Content-Type application/x-www-form-urlencoded with a blank request body which returns all of the object type depending on which URI I specify.
I can also get the same to work with something like PageNum=1&ResultsPerPage=1 in the request body and I have figured out how to incorporate that into the signature so I get a valid response.
However no matter how I format it, I cannot get anything other than a 401 response when I try to use a filter (something basic like Filter=FAMILYNAME :EQUALS: Doe). I've read over the OAuth Core 1.0 Revision A specifications on how all parameter names and values are escaped using the [RFC3986] percent-encoding. However I feel like I'm missing a step or formatting incorrectly. I've seen inconsistent information in my searching through Intuit's forums on what exactly is the proper format.
Any help on this would be greatly appreciated. I've been struggling with this for a good week now.
The response I get when trying to use a filter is:
HTTP Status 401 - message=Exception authenticating OAuth; errorCode=003200; statusCode=401
----Update----
I'm am seeing the same error when I try to use filters with the New IPP Developer Tools - IPP API Explorer. I'm using the IDS V2 QBO API Explorer. I'm able to use that tool to do a retrieve all Post and the response shows all of my customers, but when I try to use a filter I get :
Server Error
401 - Unauthorized: Access is denied due to invalid credentials.
You do not have permission to view this directory or page using the credentials that you supplied.
Any Ideas? If I'm getting the same error from the API Explorer tool, it makes me think the problem is something else entirely.
----Final Update----
I have finally had success with filters and I believe I have figure out what my problem was. I was always suspicious that I was able to get queries with pagination like "PageNum=1&ResultsPerPage=1" to work, but could not get something like "Filter=FAMILYNAME :EQUALS: Doe". I suspected there problem was with the white space in the filter format. What threw me off tracking this down earlier was that I could not get the filters to work in the IDS V2 QBO API Explorer. That made me suspect there was something else going on. I decided to ignore the API Explorer all together and focus on why I could get it to work the one way but no the other.
I believe my problem came down to improper encoding of the Filter's value in the signature. That explains the 401 invalid signature errors I was getting.
"Filter=Name :EQUALS: Doe" becomes "Filter=Name%20%3AEQUALS%20%3ADoe" after normalization.
Percent-Encoding that should give "Filter%3DName%2520%253AEQUALS%2520%253ADoe".
In essence you have to "double" encode the blank space and the colons, but not the equal sign. I tried many permutations of doing the encoding, but believe my mistake was that I was either not "double" encoding, or when I was double encoding I was including the '=' sign. Either way breaks your signature. Thanks for everyone's input.
I believe my problem came down to improper encoding of the Filter's value in the signature. That explains the 401 invalid signature errors I was getting.
I used an online tool to take me through the steps in properly signing an Oauth request. While going through those steps I realized my problem was with the steps where you normalize the request parameters and then percent-encode them. I was including the '=' of the filter in the normalization step, which breaks your signature. The tool I used can be found at:
http://hueniverse.com/2008/10/beginners-guide-to-oauth-part-iv-signing-requests/
Thanks for everyone's input.
Do you get a 401 with the same request in the API Explorer?
http://ippblog.intuit.com/blog/2013/01/new-ipp-developer-tool-api-explorer.html
Also, are you using the static base URL or retrieving it at runtime?
https://ipp.developer.intuit.com/0010_Intuit_Partner_Platform/0050_Data_Services/0400_QuickBooks_Online/0100_Calling_Data_Services/0010_Getting_the_Base_URL
If you are using the static base URL, try switching to the runtime base URL to see if you still get the error.
peterl answered one of my questions on here that may also answer yours. I had been trying to put the Filters in the body when they should have gone into the header. Here was peterl's code sample for getting all unpaid invoices (open balance greater than 0.00) for a particular customer.
