# this test demonstrates how to link up the toggl API into a google sheet
# in order to do this, you'll need to first setup your google account developer environment
# to do this, you can follow the instructions here: http://tinaja.computer/2017/10/27/gspread.html
# additional information about the spread API here: https://github.com/burnash/gspread

# as such, to run this test you'll need to define the following env variables
# TOGGL_API_KEY : your toggl api key
# WORKSPACE_ID: a workspace id that you'd like to dump data for
# KEYFILE: the full path to your google suite keyfile (keep this secret/safe!)
# SHEET_URL: the url of the google sheet you are writing to
