//the limit is the amount of items per page - in this case it would be 2 items (default is 100)

//generate and email accounts report csv
var accountResponse = coinbaseProClient.ReportsService.CreateNewAccountReportAsync(reportDateFrom, reportDateTo, accountId, "BTC-USD", "[email protected]", FileFormat.Csv);

//generate and email fills report pdf
var fillsResponse = coinbaseProClient.ReportsService.CreateNewFillsReportAsync(reportDateFrom, reportDateTo, "BTC-USD", accountId, "[email protected]", FileFormat.Pdf);

You can gain greater control of the http requests by implementing CoinbasePro.HttpClient.IHttpClient and passing that into the CoinbasePro constructor.

var myWay = new MyNamespace.MyHttpClient();

//create an authenticator with your apiKey, signature and passphrase
var authenticator = new Authenticator("<apiKey>", "<signature>", "<passphrase>");

//create the CoinbasePro client and set the httpClient to my way of behaving
var coinbaseProClient = new CoinbasePro.CoinbaseProClient(authenticator, myWay);

Logging is provided by Serilog - https://github.com/serilog/serilog

//configure the application logging to output to console and a file called log.txt
Serilog.Log.Logger = new LoggerConfiguration()
				.MinimumLevel.Debug()
				.WriteTo.Console()
				.WriteTo.File("log.txt",
					rollingInterval: RollingInterval.Day,
					rollOnFileSizeLimit: true)
				.CreateLogger();

//create an authenticator with your apiKey, signature and passphrase
var authenticator = new Authenticator("<apiKey>", "<signature>", "<passphrase>");

//create the CoinbasePro client
var coinbaseProClient = new CoinbasePro.CoinbaseProClient(authenticator);

//use one of the services 
var response = await coinbaseProClient.OrdersService.PlaceMarketOrderAsync(OrderSide.Buy, "BTC-USD", 1);
