This is a rather magical function that calls a series of concrete credential-fetching functions, each wrapped in a tryCatch(). token_fetch() keeps trying until it succeeds or there are no more functions to try. Use cred_funs_list() to see the current registry, in order. See the vignette How gargle gets tokens for a full description of token_fetch().

token_fetch(scopes = NULL, ...)

Arguments

scopes

A character vector of scopes to request. Pick from those listed at https://developers.google.com/identity/protocols/googlescopes.

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.

...

Additional arguments passed to all credential functions.

Value

An httr::Token or NULL.
