R retreive information from Eikon cloud - r

Question

I am trying to get data from Eikon Elektron cloud platform.
I ran following codes from https://github.com/Refinitiv/websocket-api/blob/master/Applications/Examples/R/market_price_authentication.R:
library(curl)
> content = paste("grant_type=", "password","&username=", user, "&password=", password, sep="")
> h <- new_handle(copypostfields = content)
> h
<curl handle> (empty)
> handle_setheaders(h,
+ "Content-Type" = "application/x-www-form-urlencoded"
+ )
> handle_setopt(h, ssl_verifypeer = FALSE, ssl_verifyhost = FALSE)
> auth_url = paste("https://", auth_hostname, sep="")# ":", auth_port, "/getToken", sep="")
> auth_url
[1] "https://api.refinitiv.com/auth/oauth2/v1/token"
> req <- curl_fetch_memory(auth_url, **handle = h**)
> req
$url
[1] "https://api.refinitiv.com/auth/oauth2/v1/token"
$status_code
[1] 400
$type
[1] "application/json"
**> h
<curl handle> (https://api.refinitiv.com/auth/oauth2/v1/token)**
> res_headers = parse_headers(req$headers)
> auth_json_string = rawToChar(req$content)
> auth_json = fromJSON(auth_json_string)
> cat(toJSON(auth_json, pretty=TRUE, auto_unbox=TRUE))
{
"error": "invalid_request"
}
As you can see, I got invalid request error. I think the problem lies in curl_fetch_memory and that the handle=h is using same input as auth_url, however it should use something similiar to the input of content. What can I change in my code to make it work?

I found solution how to access the URL. In github was wrongly written that app_id in R file should equal to the code from the App Key generator in Reuters. However, app_id and client_id are different things and you should add client_id=value from App Key generator (not app_id).+ also do not forget to include trapi and etc.. to your content.
