The dev version of curlconverter (devtools::install_github("hrbrmstr/curlconverter") can convert curl command-line strings with authentication and verbose params now:

Copy your URL to the clipboard:

curl -v -u abcdefghij1234567890:X -H "Content-Type: application/json" -X GET 'https://domain.freshdesk.com/api/v2/tickets'

Then run:

library(curlconverter)
req <- make_req(straighten())[[1]]

The following will now be in your clipboard:

httr::VERB(verb = "GET", url = "https://domain.freshdesk.com/api/v2/tickets", 
    httr::authenticate(user = "abcdefghij1234567890", 
        password = "X"), httr::verbose(), 
    httr::add_headers(), encode = "json")

but req is now also a callable function. You can see that by doing:

req
## function () 
## httr::VERB(verb = "GET", url = "https://domain.freshdesk.com/api/v2/tickets", 
##     httr::authenticate(user = "abcdefghij1234567890", password = "X"), 
##     httr::verbose(), httr::add_headers(), encode = "json")

or by actually calling it:

req()

I usually reformat the function source to make it more readable:

httr::VERB(verb = "GET", 
           url = "https://domain.freshdesk.com/api/v2/tickets", 
           httr::authenticate(user = "abcdefghij1234567890", password = "X"),
           httr::verbose(), 
           httr::add_headers(), 
           encode = "json")

and you can easily translate that to a plain GET call without namespacing:

GET(url = "https://domain.freshdesk.com/api/v2/tickets", 
    authenticate(user = "abcdefghij1234567890", password = "X"), 
    verbose(), 
    add_headers(), 
    encode = "json"))

We can validate it working with authenticated curl command-lines by a small substitution in your example:

curl_string <- 'curl -v -u abcdefghij1234567890:X -H "Content-Type: application/json" -X GET "https://httpbin.org/basic-auth/abcdefghij1234567890/X"'

make_req(straighten(curl_string))[[1]]()

## -> Host: httpbin.org
## -> Authorization: Basic YWJjZGVmZ2hpajEyMzQ1Njc4OTA6WA==

## {

##   "user": "abcdefghij1234567890"
## }

You can use httr to do this as follows:

require(httr)
GET('https://domain.freshdesk.com/api/v2/tickets',
    verbose(),
    authenticate("user", "passwd"),
    content_type("application/json"))
