I finally got this working. I went back to my Google email account and deleted the API keys. I added the new software ( updated Class ) and created a new API key. It finally worked.
Now I will take my existing email program and make the appropriate updates to allow this system to also work within the same usage of SMTP and IMAPI protocals that are already employed.
Thank you Lailton for the assistance.
I am now wondering, also, if we can get a FWH app authorized by Google. Since we make no money off of this addition to an existing program, is it free, or is Google expecting us to pay for some type of subscription. ( That's a non-starter for me ). I did try the authorize process and the initial response was that it did not meet Google's security requirements.
