The way HTTP basic auth works, you encode the username and password together as base64, separated by a colon. In the Asana API the key is the username and there is no password.

From the docs at https://asana.com/developers/documentation/getting-started/authentication#sts=API%20Keys :

Note: Most utilities and libraries that allow you to specify a username and password will handle proper encoding of the header for you. However, if you need to set the Authorization header manually, the header value is constructed by adding a colon (:) to the API key, then base64-encoding that string. You can read more on basic authentication if you need further details.

So, you should probably do:

byte[] encodedByte = System.Text.ASCIIEncoding.ASCII.GetBytes(APIKey + ":")
