#' Export user subscription information.
#'
#' @param target character string. Aim of a request: a domain, a directory or a URL
#' @param token character string. Authentication token. Should be available through enviromental variables
#'     after authentication with function \code{rah_auth()}
#' @param mode character string. Mode of operation: exact, domain, subdomains or prefix. See more in Details section
#' @param metrics character vector of columns to select. See more in Details section
#' @param limit integer. Number of results to return
#' @param order_by character vector of columns to sort on. See more in Details section
#' @param where character string - a condition created by \code{rah_condition_set()} function that generates proper
#'     \code{"where"} condition to satisfy. See more in Details section
#' @param having character string - a condition created by \code{rah_condition_set()} function that generates proper
#'     \code{"having"} condition to satisfy. See more in Details section

#' @details
#'     \strong{1. available metrics} - you can select which columns (metrics) you want to download and which one
#'     would be useful in filtering, \strong{BUT not all of them can always be used} in \code{"where"} &
#'     \code{"having"} conditions:
#'
#'     \tabular{lllll}{
#'     Column \tab Type \tab Where \tab Having \tab Description\cr
#'     rows_left    \tab int    \tab - \tab - \tab Number of rows available for making API requests.        \cr
#'     rows_limit   \tab int    \tab - \tab - \tab Total number of rows available for the subscription plan.\cr
#'     subscription \tab string \tab - \tab - \tab Name of the API subscription plan.
#'     }
#'
#'     \strong{2. \code{"mode"}} parameter can take 4 different values that will affect how the results will be grouped.
#'
#' Example of URL directory with folder:
#'     \itemize{
#'       \item \strong{Example URL:} ahrefs.com/api/
#'       \item \strong{exact:} ahrefs.com/api/
#'       \item \strong{domain:} ahrefs.com/*
#'       \item \strong{subdomains:} *ahrefs.com/*
#'       \item \strong{prefix:} ahrefs.com/api/*
#'     }
#' Example of URL directory with subdomain:
#'     \itemize{
#'       \item \strong{Example URL:} apiv2.ahrefs.com
#'       \item \strong{exact:} apiv2.ahrefs.com/
#'       \item \strong{domain:} apiv2.ahrefs.com/*
#'       \item \strong{subdomains:} *apiv2.ahrefs.com/*
#'       \item \strong{prefix:} apiv2.ahrefs.com/*
#'     }
#'
#'    \strong{3. \code{"order_by"}} parameter is a character string that forces sorting of the results. Structure:
#'     \itemize{
#'       \item \strong{Structure:} "\code{column_name}:asc|desc"
#'       \item \strong{Single column example:} "first_seen:asc" ~ this sorts results by \code{first_seen}
#'       column in ascending order
#'       \item \strong{Multi column example:} "last_seen:desc,first_seen:asc" ~ this sorts results
#'           by 1) \code{last_seen} column in descending order, and next by 2) \code{first_seen} column in
#'           ascending order
#'     }
#'
#'     \strong{4. \code{"where"} & \code{"having"}} are \strong{EXPERIMENTAL} parameters of condition sets
#'         (character strings) that control filtering the results. To create arguments:
#'         \enumerate{
#'           \item use \code{rah_condition()} function to create a single condition, for example:
#'               \code{cond_1 <- rah_condition(column_name = "links", operator = "GREATER_THAN", value = "10")}
#'           \item use \code{rah_condition_set()} function to group single conditions into final condition
#'               string, for example: \code{fin_cond <- rah_condition_set(cond_1, cond_2)}
#'           \item provide final condition to proper report function as a parameter, for example:
#'               \code{RAhrefs::rah_subscription_info()}
#'         }
