User Permission Denied Different Client Library

[Mark Hill]

I've created a small application with the php client library. Now i'm considering the possibility of using the .NET library but i'm running into an issue. Every time I attempt to perform any basic actions I get a "user permission denied trigger null" error. However, I can access a test account I setup fine, but the problems happen when I use the exact same OAUTH/Developer info that is being used by the currently running application. Any idea on what the problem might be?

Thank You,

Hi Mark,

For your .NET API request, your OAuth credentials don't match the client ID specified in the request, or any of its MCCs. Please check you have set your OAuth2.0 credential properly. You could refer the OAuth2.0 guide for details.

Hi Umesh,

The values that are defined in the php config file, and that are also in the .net config file are:

User Agent

Developer Token

Client Customer Id

OAuth2 Client Id

OAuth2 Client Secret 

OAuth2 Refresh Token

The only difference is that the .net config file specifies that the Oauth mode is "application." Do I need different OAuth2 credentials for each application? Or should everything be working correctly with all of the settings being copied over?

Hi Mark,

The OAuth2.0 client id and client secret key are specific to the application. You need to create new client id and client secret key for .NET library selecting Application Type as Web application. Please check out our OAuth2.0 guide of .NET library for details information.
