Uber Authentication failed "HTTP Status 401: Unauthorized, Response: {"error": "invalid_client"}"

Question

i am using this library for Uber Authetication

https://developer.uber.com/v1/auth/

I have done like this

func doOAuthUber(){

let oauthswift = OAuth2Swift(
    consumerKey:    "fXfXXXXXXXUo9vtKzobXXXXXUDO",
    consumerSecret: "e5XXXXXXXq2w63qz9szEx7uXXXXXXo03W",
    authorizeUrl:   "https://login.uber.com/oauth/authorize",
    accessTokenUrl: "https://login.uber.com/oauth/token",
    responseType:   "code"
)

var originalString = "jamesappv2://oauth/callback"
var encodedCallBackUrl = originalString.stringByAddingPercentEncodingWithAllowedCharacters(.URLHostAllowedCharacterSet())

println("encodedCallBackUrl: \(encodedCallBackUrl)")


let state: String = ""
oauthswift.authorizeWithCallbackURL( NSURL(string: encodedCallBackUrl!)!, scope: "request%20history", state: state, success: {
    credential, response in

    println(credential.oauth_token)
    self.personalDriverLoader.stopAnimating()



    }, failure: {(error:NSError!) -> Void in

        self.personalDriverLoader.stopAnimating()
        println(error.localizedDescription)
})

}

but getting this response HTTP Status 401: Unauthorized, Response: {"error": "invalid_client"}

I have triple checked that my client_id (consumerKey) and secret (consumerSecret) are correct. What I have done wrong here

Update:1

this is wired I changed responseType: "code" to responseType: "token" and it worked Got My access token. but I am getting an other issue now

now when ever I try to call the request endpoint api

using below code

@IBAction func btnRequestUberdidClicked(sender: AnyObject) {

    self.callRequestAPI("https://sandbox-api.uber.com/v1/requests")

}

func callRequestAPI(url:String){

    var configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    var session = NSURLSession(configuration: configuration)

    let params:[String: AnyObject] = [
                "product_id" : selectedUberProductId,
                "start_latitude" : start_lat,
                "start_longitude" : start_lng,
                "end_latitude" : end_lat,
                "end_longitude" : end_lng]



    appDelegate.oauthswift.client.post(url, parameters: params,
    success: { data, response in

    let dataString = NSString(data: data, encoding: NSUTF8StringEncoding)


         println("Success")

                    println(data)

                    println(response)


        }, failure: {(error:NSError!) -> Void in

                         println("Error")

                    println(error)
    })


}

I am getting this response

}

You will have to modify the library where possible and be able to print the auth code returned from Uber. I was facing a similar problem with Uber authentication using objective C and then I realised from my logs that Uber was appending #_ to the authorization code. So when this code was used to fetch the access token, it would fail with (401) unauthorised error simply saying the auth code is invalid, and indeed it was.

See attached image below.

So eventually I had to removed the #_ from the auth code before using it to get the access token.

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params1 = @{@"client_secret":UBER_CLIENT_SECRET,
                          @"client_id":UBER_CLIENT_ID,
                          @"grant_type":@"authorization_code",
                          @"redirect_uri":UBER_REDIRECT_URL,
                          @"code":[app.uberAuthCodeStr stringByReplacingOccurrencesOfString:@"#_" withString:@""]};
                    //******* THE FIX IS HERE ON THIS LINE ^^^

[manager POST:@"https://login.uber.com/oauth/v2/token" parameters:params1 success:^(AFHTTPRequestOperation *operation, id responseObject){
    NSLog(@"JSON: %@", responseObject);
    //
    app.uberBearerAccess_token = [responseObject valueForKey:@"access_token"];
    app.uberBearerRefresh_token = [responseObject valueForKey:@"refresh_token"];
    NSLog(@"Bearer AccessToken = %@ ",app.uberBearerAccess_token);
    // Save access token to user defaults for later use.
    NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];
    NSNumber *seconds = [responseObject objectForKey:@"expires_in"];
    NSDate *expiryDate = [[NSDate date] dateByAddingTimeInterval:seconds.intValue];
    [defaults setObject:expiryDate forKey:KEY_UBER_TOKEN_EXPIRE_DATE];
    [defaults setObject:app.uberBearerAccess_token forKey: KEY_UBER_TOKEN];
    [defaults setObject:app.uberBearerRefresh_token forKey: KEY_UBER_REFRESH_TOKEN];
     [defaults setObject:app.uberAuthCodeStr forKey: KEY_UBER_AUTH_CODE];
    [defaults synchronize];
    loginView.hidden = YES;
    [self goUberChat];
    //
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@':%@", error,params1);
    [ProgressHUD dismiss];
}];

Hope this helps you or anyone with a similar problem.

Try this for call Uber Api

 NSString *string=[NSString stringWithFormat:@"https://api.uber.com/v1/products"];
    NSURL *url=[NSURL URLWithString:string];
    AFHTTPSessionManager *manager=[[AFHTTPSessionManager alloc]initWithBaseURL:url];
    NSDictionary *parameters = @{@"server_token":@"Your token",@"latitude":@"latitude",@"longitude":@"longitude",
    [manager GET: parameters:parameters progress:nil success:^(NSURLSessionTask *task,id responseObject){
    } failure:^(NSURLSessionTask *operation , NSError *error)
}];
