redcap_next_free_record_name: Determine free available record ID

Description

Determines the next available record ID.

Usage

redcap_next_free_record_name(
  redcap_uri,
  token,
  verbose = TRUE,
  config_options = NULL,
  handle_httr = NULL
)

Value

a base::character vector of either length 1 (if successful) or length 0 (if not successful).

Arguments

redcap_uri

The uri/url of the REDCap server typically formatted as "https://server.org/apps/redcap/api/". Required.

token

The user-specific string that serves as the password for a project. Required.

verbose

A boolean value indicating if messages should be printed to the R console during the operation. The verbose output might contain sensitive information (e.g. PHI), so turn this off if the output might be visible somewhere public. Optional.

config_options

A list of options passed to httr::POST(). See details at httr::httr_options(). Optional.

handle_httr

The value passed to the handle parameter of httr::POST(). This is useful for only unconventional authentication approaches. It should be NULL for most institutions. Optional.

Details

If the API call is unsuccessful, a value of character(0) will be returned (i.e., an empty vector). This ensures that a the function will always return an object of class base::character.

Examples

uri      <- "https://redcap-dev-2.ouhsc.edu/redcap/api/"
token    <- "9A068C425B1341D69E83064A2D273A70"
# Returns 6
if (FALSE) {
REDCapR::redcap_next_free_record_name(redcap_uri = uri, token = token)
}
