I have a C# application using version 2.0.1.0 of the Rally Rest API for .NET. The application will successfully query Rally for data, but when I try to create an object, an error is returned indicating invalid key. This issue started today and is occurring for multiple users of the application. I use the following line of code to authenticate.
myRestApi = new RallyRestApi(Rally_username, Rally_password, Rally_URL, "v2.0", myProxy);
I have read some help online indicating the need for a security token, however this note makes me feel like that is not needed: "Note: When using any of the Rally REST Toolkits or the App SDK this will be automatically handled. "
I have tried updating to version 3.0 (Beta), but this does not resolve the problem.
