Authorize googlesheets4 to view and manage your Google Sheets. This function is a
wrapper around gargle::token_fetch().
By default, you are directed to a web browser, asked to sign in to your
Google account, and to grant googlesheets4 permission to operate on your
behalf with Google Sheets. By default, these user credentials are cached in a
folder below your home directory, ~/.R/gargle/gargle-oauth, from where
they can be automatically refreshed, as necessary. Storage at the user
level means the same token can be used across multiple projects and
tokens are less likely to be synced to the cloud by accident.
If you are interacting with R from a web-based platform, like RStudio
Server or Cloud, you need to use a variant of this flow, known as
out-of-band auth ("oob"). If this does not happen automatically, you
can request it yourself with use_oob = TRUE or, more persistently, by
setting an option via options(gargle_oob_default = TRUE).
gs4_auth(
email = gargle::gargle_oauth_email(),
path = NULL,
scopes = "https://www.googleapis.com/auth/spreadsheets",
cache = gargle::gargle_oauth_cache(),
use_oob = gargle::gargle_oob_default(),
token = NULL
)Optional. Allows user to target a specific Google identity. If
specified, this is used for token lookup, i.e. to determine if a suitable
token is already available in the cache. If no such token is found, email
is used to pre-select the targetted Google identity in the OAuth chooser.
Note, however, that the email associated with a token when it's cached is
always determined from the token itself, never from this argument. Use NA
or FALSE to match nothing and force the OAuth dance in the browser. Use
TRUE to allow email auto-discovery, if exactly one matching token is
found in the cache. Defaults to the option named "gargle_oauth_email",
retrieved by gargle_oauth_email().
JSON identifying the service account, in one of the forms
supported for the txt argument of jsonlite::fromJSON() (typically, a
file path or JSON string).
A character vector of scopes to request. Pick from those listed at https://developers.google.com/identity/protocols/oauth2/scopes.
For certain token flows, the
"https://www.googleapis.com/auth/userinfo.email" scope is unconditionally
included. This grants permission to retrieve the email address associated
with a token; gargle uses this to index cached OAuth tokens. This grants no
permission to view or send email. It is considered a low value scope and
does not appear on the consent screen.
Specifies the OAuth token cache. Defaults to the option named
"gargle_oauth_cache", retrieved via gargle_oauth_cache().
Whether to prefer "out of band" authentication. Defaults to
the option named "gargle_oob_default", retrieved via
gargle_oob_default().
A token with class Token2.0 or an object of
httr's class request, i.e. a token that has been prepared with
httr::config() and has a Token2.0 in the
auth_token component.
Most users, most of the time, do not need to call gs4_auth()
explicitly -- it is triggered by the first action that requires
authorization. Even when called, the default arguments often suffice.
However, when necessary, this function allows the user to explicitly:
Declare which Google identity to use, via an email address. If there are multiple cached tokens, this can clarify which one to use. It can also force googlesheets4 to switch from one identity to another. If there's no cached token for the email, this triggers a return to the browser to choose the identity and give consent.
Use a service account token.
Bring their own Token2.0.
Specify non-default behavior re: token caching and out-of-bound authentication.
For details on the many ways to find a token, see
gargle::token_fetch(). For deeper control over auth, use
gs4_auth_configure() to bring your own OAuth app or API key.
