get_token is a function that retrieves a token string from the API that
is required as part of submitting a correct tidy_depot_api request in the token parameter.
get_token(email_address = get_secret_email(), secret = get_secret())email address associated with secret
secret used for generating API token
The token string used for Authentication header in API calls
get_token should work as a function call without having to pass any user parameters provided
the user has correctly run store_secret_credentials to save these credentials locally in an
.Renviron file. get_token will then use that information to request a token string from the API
and return this string. The string can then be used for the tidy_depot_api function int he token
parameter to request data and validate the user's credentials.
