Import CSV from API output to google - api

Question

I have absolutly no idea of what I'm doing but I'm trying to import CSV data from API output into a google sheets.
The data I want to import are bookings data, aleady generated as a csv file and I simply need to import all the data the first time and then update it (no need to re-import all the datas from last year)
The API URL is:
https://www.beds24.com/api/csv/getbookingscsv
I need however to enter my username and my password and if necessary a date range.
So in my head it would be:
One script for the year booking import
username XXXXX
password •••••
datefrom
dateto
One script for the day booking import using the date range
username XXXXX
password •••••
datefrom 2019-09-29
dateto 2019-09-29
The first look I took using googlescript I found out that I would probably need something like this:
function importCSV() {
var var bookings = beds24api.beds24GetBookings(prop_key, data_option);
var res = UrlFetchApp.fetch("https://www.beds24.com/api/csv/getbookingscsv");
var content = res.getContentText();
var authentication = {
'authentication' : {
'username' : XXXXX,
'password' : •••••
};
};
}
function beds24GetBookingsCSV(username, password, data_option){
return beds24JsonApi('https://www.beds24.com/api/csv/getbookingscsv',username, password, data_option);
};
return {
beds24GetBookings: beds24GetBookingsCSV,
};
}
Lot of you gonna get bleding eyes from this code but if I could get some help acheiving this that would be awesome!

Answer 1

I have no experience with beds24 nor do I wish to. But if you look here you will find an example of UrlFetchApp.fetch(url, options);. I believe that you'll need to include your authentication data into the options object or include them as elements of the querystring portion of the url. Look to see in beds 24 has a Google Apps Script example or possibly a Javascript example.

String url = "https://www.beds24.com/api/csv/getbookingscsv";
URL obj = new URL(url);
HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();
con.setRequestMethod("POST");
String params = "username=XXX&password=YYY";
con.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(con.getOutputStream());
wr.writeBytes(params);
wr.flush();
BufferedReader in = new BufferedReader( new InputStreamReader(con.getInputStream()));
StringBuilder response = new StringBuilder();
String inputLine;
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
System.out.println(response.toString());
# Function to get data from Beds24 API
getBeds24Data <-function(username = property_mgmt$username,
password = property_mgmt$password,
datefrom = "2019-01-01",
dateto = "2019-12-30"){
url <- "https://www.beds24.com/api/csv/getbookingscsv"
response <- httr::POST(url=url, body = list("username" = username,
"password"=password,
datefrom = datefrom,
dateto = dateto))
beds24Data <- httr::content(response,type='text/csv',col_names=T,col_types=NULL)
return(beds24Data)
}
