Hi Kudvenkat, In OauthAuthorizationserverOtions who will validate the generated token. if i modify the token how will it know the token has been changed. Is Owin running seperate server for validating tokens ?

[@SIRborioVojta]

Could somebody please help me?? When I try running this project on IIS then /token and all /api/account/... don't work

[@kathiravankkathir]

Thanks for your valuable video tutorials

[@AnkitGupta-df9xo]

[@amjadaslam5270]

[@balajiravi6961]

Hello, I am facing the same 401 unauthorized error in c#, how do I get the token in runtime. Because it is keep getting expired

[@junaidameen8303]

What if I don't want my webapi to be called even if I provide access token by fiddler and try to access webapi. Webapi should work only if request is coming from my site. could you please explain how can we achieve it?

[@remiduplan8449]

[@hermescondez6060]

How can I configure this as a sub site. Its parent is using Windows Authentication

[@dellajoseph302]

i am getting error while execute the fiddler with Rest Api request, could you please tell me the reason? i have given api url and body

[@ej2649]

I like the video but I don't understand how token is generated by the class. If those authorization classes are not created by the web api project, how can we create them? looks like it's kind of advance concept here beyond of my level.

[@sharathbabumahankali7868]

Can u make a video for that startup class and providers class

[@vivekverma319]

I did not get about /token , where it came from? pls clarify me. From where I can get this file "Startup.Auth.cs".

[@its4zahoor]

when you create the Web API MVC project, make sure you have set authentication (option on rightside) to Individual User Authentication.

From where did we get method "TOKEN" in URI localhost:34838/token, can anyone pls tell. What if I don't have to use database for crosschecking username and password instead use username and password in web config file and compare the credentials

[@TheImranbergi]

[@buzzkillbuddy4532]

Check to ensure you are using localhost/api/users and not localhost/token and changing the post request to a get request.

[@MrDpk27]

[@srinivaseppakayala236]

HI Venkat , Each time we are passing access token to get the access but can you please explain how server validates the token that we have sent for each request

[@vacalepic6768]

In a few years, no one would care about this MVC style, even .net core 6 would be outdated in a few years. Yes, concept and convention may remain

[@elderofzion]

ConfigureAuth looks different in .net 4.6.1. ApplicationOAuthProvider can't be found

[@kosovacvr]

wtf is /token - i've got 500 Internal server error

[@bctloaded985]

ctrl+f and search for /Token... for me it was located in Startup.Auth.cs. You should not be getting a 500 internal server error. If you can't find /Token, then you did not setup your project correctly.

[@Wintainment]

I also Find Error and i Have Checked /Token in Startup.Auth.cs file. please Help me @@bctloaded985

[@muhammadrehbarsheikh8498]
