I'm using Trello's Developer API's implementation of OAuth to post stuff to a list.
I've successfully made a request and got my oauth_token and oauth_token_secret back from https://trello.com/1/OAuthGetRequestToken
But when I call https://trello.com/1/OAuthAuthorizeToken, passing the oauth_token that I've just received, I get a response of 'App not found'.
Can anyone help?
EDIT: Here's what I'm getting back from https://trello.com/1/OAuthGetRequestToken
oauth_token=8d0e43fd0cc67726567d49ae5e818852&oauth_token_secret=[secret]
And here's the Authorization header I'm sending (escaped in C#)
"OAuth oauth_version=\"1.0\", oauth_signature_method=\"HMAC-SHA1\", oauth_nonce=\"8335006\", oauth_timestamp=\"1414663625\", oauth_consumer_key=\"9612eaca23c7bdd3eca60dc8c2a8159c\", oauth_signature=\"M6sLyyfHGYXOtQnLJexDx96kbFo=\", oauth_token=\"8d0e43fd0cc67726567d49ae5e818852\""
Am I doing something wrong or is this an error on Trello's end?
EDIT: I'm using RestSharp to call the Trello API, as below:
var client = new RestSharp.RestClient("https://trello.com/");
var request = new RestSharp.RestRequest("1/OAuthAuthorizeToken", Method.GET);
EDIT: Here's the complete RestSharp code:
var client = new RestSharp.RestClient("https://trello.com/");
var request = new RestSharp.RestRequest("1/OAuthAuthorizeToken", Method.GET);
Uri uri = new Uri(string.Format("{0}/{1}", client.BaseUrl, request.Resource));
string authHeader = GenerateAuthorizationHeader(uri);
//This is the output of GenerateAuthorizationHeader()
//string authHeader = "OAuth oauth_version=\"1.0\", oauth_signature_method=\"HMAC-SHA1\", oauth_nonce=\"8335006\", oauth_timestamp=\"1414663625\", oauth_consumer_key=\"9612eaca23c7bdd3eca60dc8c2a8159c\", oauth_signature=\"M6sLyyfHGYXOtQnLJexDx96kbFo=\", oauth_token=\"8d0e43fd0cc67726567d49ae5e818852\"";
request.AddHeader("Authorization", authHeader);
The GenerateAuthorizationHeader method uses OAuth.OAuthBase to generate the TimeStamp and Signature for the OAuth request.
Looks like it might be a trello problem...
this user, had the wrong key by the sounds of things.
are you 100% sure that the key is correct.
Getting "App not found" from Trello Authentication
I had the same problem, the thing here is that OAuth is version 1.0
When you get the token and token secret from the first call you have to make your user to visit https://trello.com/1/OAuthAuthorizeToken not you.
In your case you have to redirect your user to https://trello.com/1/OAuthAuthorizeToken?oauth_token=8d0e43fd0cc67726567d49ae5e818852&scope=read,write,account
He will get a page where he can Allow the access. Then you will get a verification code in the page after the authorization to continue with your process (GetAccessToken).
You can try this as a test, in a real application you have to specify a callback url and an application name in the OAuthAuthorizeToken call.

I am able generate access token with docusign site by using link https://developers.docusign.com/oauth-token-generator
But when try to get access token in our system using c# code then getting message (The remote server returned an error: (400) Bad Request.)
I follow the authenticate process mentioned in below link.
https://developers.docusign.com/esign-rest-api/guides/authentication/oauth2-code-grant
I able to get authentication code. I used this authentication code to hit API (https://account-d.docusign.com/oauth/token).
Below is my code sample
string integrationKey = "key removed";
string secretKey = "key removed";
var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://account-d.docusign.com/oauth/token");
httpWebRequest.ContentType = "application/x-www-form-urlencoded";
httpWebRequest.Method = "POST";
string apiStoreConsumer = "removed";
httpWebRequest.Headers.Add("Authorization", "Basic " + apiStoreConsumer);
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string input = "authorization_code&authorization_code= <authentication code goes here>;
streamWriter.Write(input);
streamWriter.Flush();
streamWriter.Close();
}
WebResponse response = (HttpWebResponse)httpWebRequest.GetResponse();
Query:
Why am I getting 400 error?
Do we have any expiry time for access token, if yes then how long?
Does authentication code get change for every request?
Please help me on this.
Thank You!
I recommend you use a library for OAuth in .NET/C#.
If you want to see how this is done, please clone this repo.
The issue is that you need to first get a code and then exchange it for a token. There are 2 steps involved if you do this manually.
The first step requires you to authenticate the user in a browser before you can call any API.
During that step you need to pass in your integration key and redirect back to your URL.
Once redirected back you'll receive a code that can be exchanged for an access token using the API call you had talks about.
I'm trying to upload a photo using the Picasa Web Albums Data API in C# and I'm using RestSharp to help me with the HTTP requests.
I have the client ID and the client secret, but I don't know how to put that on the http request to make the authentication.
I'm getting the error:
Modification only allowed with api authentication.
The StatusCode that is returning is Forbidden
Here is my code where is my user ID and is my album ID.
The method "Authenticantion()" returns a token that I already have.

The OAuth2 authentication normally happens inside a user flow, where the user makes the login with the user and allow (or not) some scopes to the app (e.g. access Picasa, read only for Google Drive).
You can check the complete flow through this link: OAuthPlayground. And get your own token at the end of the flow to use with your HTTP requests. One thing to take care is about refresh the tokens, inside the playground it's possible to set to never expire. But on the real world you would need to implement this refresh.
The Picasa API is a little outdated, I'd recommend you to use GoogleDrive instead, it's much more flexible and up to date.
GoogleDrive_API_Docs
It's also possible to make this flow via OAuth2_ Server to server, but I never tried before.
I am a bit confused that when I get the error:
Problem during authentication process, check headers!
Unable to authenticate user, incorrect token
There is definitely something wrong with request header.
Can any one tell me the correct way of sending a request to GetResponse API?
I am using this way:
var request = new RestRequest("/campaigns", Method.GET);
request.AddHeader("X-Auth-Token", "api-key " + auth.myAuthorizationKey);
The header looks like this in request while debugging:
{X-Auth-Token=api-key d042eeae34ce076913681cc5c872741e2c5f88d2}
Use APIKEY instead AuthorizationKey
trying to send Tweet with the image attached, using RestSharp:
_client = new RestClient("https://api.twitter.com")
{
Authenticator = OAuth1Authenticator.ForProtectedResource(Key, Secret, Token, TokenSecret)
};
RestRequest request = new RestRequest("/1.1/statuses/update_with_media.json", Method.POST);
request.AddFile("media", att.File, att.FileName, "base64");
request.AddParameter("status", postStatus.Text);
var result = await _client.ExecuteTaskAsync(request);
The result is "Could not authenticate you" error no - 32
Thanks
UPDATE: All authentication parameters start from oauth_ and go in alphabetical order, the token, token secret, app key and app key secret are correct, the update status without media works perfectly.
UPDATE 2:
Solution
var request = new RestRequest("/1.1/statuses/update_with_media.json", Method.POST);
request.AlwaysMultipartFormData = true;
request.AddParameter("status", message, ParameterType.UrlSegment);
request.AddFile("media[]", file, filename, "application/octet-stream");
var result = _client.Execute(request);
This is actually a problem with restsharp 104.4 (version in Nuget as of time of writing)
We hit the same problem, but your solution above did not work for us. The UrlSegment parameter fails on a status update, and while it does not fail on a call to update_with_media, it also does not post the status, just the picture.
The problem is with OAuth1Authenticator, it does not ignore non-oauth POST or GET parameters, hence the authentication errors above, and why the URL segment parameter "works".
To fix this, get the latest version of RestSharp from GitHub and use that instead.
For those interested, the checkin involved was only made a month or so after the release and can be found here.
I am struggling to call APIs hosted in Google Cloud https://apis-explorer.appspot.com/apis-explorer/?base=https%3A%2F%2Finnovative-glass.appspot.com%2F_ah%2Fapi#p/mirror/v1/
Up to my understanding, APIs are exposed as REST service. I need to make rest service call from .net application.
I have done OAuth Authentication. I am passing access_token as per the guidance given https://developers.google.com/accounts/docs/OAuth2WebServer
My Code:
UriBuilder uriBuilder = new UriBuilder("https://innovative-glass.appspot.com/_ah/api/mirror/v1/timeline");
string userId = Session["userId"] as string;
var state = Utils.GetStoredCredentials(userId);
NameValueCollection queryParameters = HttpUtility.ParseQueryString(uriBuilder.Query);
queryParameters.Set("access_token", state.AccessToken);
uriBuilder.Query = queryParameters.ToString();
var request = (HttpWebRequest)WebRequest.Create(uriBuilder.ToString());
request.Method = "GET";
var response = (HttpWebResponse)request.GetResponse();
I am getting UnAuthorized exception.
Is my understanding is right? Am I doing right way?
It seems that cloud endpoints don't use the Google API default of accepting access_token as query parameter. According to the Discovery document the equivalent query parameter is oauth_token so it should work with:
queryParameters.Set("oauth_token", state.AccessToken);
Alternatively (which in my opinion is the better solution) you can also set the Authorization header of the request instead of adding the token as query parameter:
request.Headers.Add("Authorization", "Bearer " + state.AccessToken);
Where are you getting the AccessToken from, and are you sure it is still a valid token? Remember that access tokens expire about an hour after being generated, although can be revoked earlier.
Clicking on the sign-in button at innovative-glass.appspot.com gives me an origin mismatch error, so it looks like you may also have a configuration issue.
Have you been able to get it to work using just the API Explorer?
