Google APIs Access Token generator

This Windows CLI utility implements the Google APIs OAuth2 authorization using Google Libraries and generates an output file with the Access Token information.

Json and "Key=Value" output file formats supported.

You will need to configure a service account and generate a '*.p12' certificate with appropriate security settings on Google Developers Console. Make sure to specify the scope under -s option using a comma separated pattern without spaces to specify more than one.

For basic usage, execute:

GoogleOAuth2 -u service-account@your-project.iam.gserviceaccount.com -c certificate.p12 -s "https://www.googleapis.com/auth/spreadsheets"

JSON output example:

{
 "access_token": "ya29.c.ElolBh1E0-9GSkssqauNE4ZmmYWhje3Pxkx8CF8V0AU6ddG51fplaJuB7NHJkRgO_Hch16WBSMR7BD7N14B-397Q8iAKlCSp7-65CixQC8QgxdZE_QHMEYkXOAs",
