[גרי סלוב‎]

im running localy the: "GetRefreshToken.php" file, im inserting all the parameters and when i hit the line:

"[OPTIONAL] enter any additional OAuth2 scopes as a space delimited string here ..."

im going to the

"https://accounts.google.com/o/oauth2/v2/auth?response_type=code&access_type=offline&client_id=..."

with my clientID, but then i hit enter to get the token it calls an error:

Error: invalid_request

Missing required parameter: scope.
