Low-level functions to execute one or more Drive API requests and, perhaps, process the response(s). Most users should, instead, use higher-level wrappers that facilitate common tasks, such as uploading or downloading Drive files. The functions here are intended for internal use and for programming around the Drive API. Three functions are documented here:

  • request_make() does the bare minimum: calls gargle::request_make(), only adding the googledrive user agent. Typically the input is created with request_generate() and the output is processed with gargle::response_process().

  • do_request() is simply gargle::response_process(request_make(x, ...)). It exists only because we had to make do_paginated_request() and it felt weird to not make the equivalent for a single request.

  • do_paginated_request() executes the input request with page traversal. It is impossible to separate paginated requests into a "make request" step and a "process request" step, because the token for the next page must be extracted from the content of the current page. Therefore this function does both and returns a list of processed responses, one per page.


request_make(x, ...)

do_request(x, ...)

  n_max = Inf,
  n = function(res) 1,
  verbose = deprecated()



List, holding the components for an HTTP request, presumably created with request_generate() Should contain the method, url, body, and token.


Optional arguments passed through to the HTTP method.


Maximum number of items to return. Defaults to Inf, i.e. there is no limit and we keep making requests until we get all items.


Function that computes the number of items in one response or page. The default function always returns 1 and therefore treats each page as an item. If you know more about the structure of the response, you can pass another function to count and threshhold, for example, the number of files or comments.


[Deprecated] This logical argument to individual googledrive functions is deprecated. To globally suppress googledrive messaging, use options(googledrive_quiet = TRUE) (the default behaviour is to emit informational messages). To suppress messaging in a more limited way, use the helpers local_drive_quiet() or with_drive_quiet().


request_make(): Object of class response from httr.

do_request(): List representing the content returned by a single request.

do_paginated_request(): List of lists, representing the returned content, one component per page.
