Using C# to connect to ConnectWise API

I intend to create a program using C# which will update tickets in ConnectWise using, eventually, data from another API.

Thus far I've wanted to test to GET some invoices. For this I installed the latest SDK and referenced it in Visual studio (SDK 2017.3).

The documentation claims that this should suffice:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using ConnectWiseDotNetSDK;
using ConnectWiseDotNetSDK.ConnectWise;
using ConnectWiseDotNetSDK.ConnectWise.Client;
using ConnectWiseDotNetSDK.ConnectWise.Client.System.Api;
using ConnectWiseDotNetSDK.ConnectWise.Client.System.Model;

private static List<Invoice> getInvoices()
{
    var client = getApiClient();
    var invoicesApi = new InvoiceApi(client);
    var response = invoicesApi.GetInvoices();
    var invoices = response.GetResult<List<Invoice>>();
    foreach (var invoice in invoices)
    {
        Console.WriteLine(invoice);
    }
    return invoices;
}

(where I have added all the using .... rows, the documentation does not clarify which are needed).

This however gives me an error that getApiClient() does not exist in this context. I reckon I must create the function, which will provide my authentication etc. Thus I've done:

private static getApiClient()
{
    string BaseUri = "https://eu-myconnectwise.net/v4_6_Release/apis/3.0/finance/invoices"
    string ContentType = "application/json";
    string Authstring = "xxxxyyxxxx";
}

This does not work. I have no idea how to create the client variable in the main program.

Has anyone gotten the SDK to work using C#?

Unfortunately, while the Connectwise documentation is getting better, there's still a whole heap of digging around that you have to do to get the end result you're after.

Here's a short example based on the ZIP file at the bottom of the answer.

const string cw_app_id = "<YourAppID>";
const string cw_site = "<YourConnectWiseInstance>";
const string cw_companyname = "<YourConnectWiseCompany>";

const string public_key = "<PublicKey>";
const string private_key = "<PrivateKey>";

private static ApiClient GetApiClient()
{
    return new ApiClient(cw_app_id, cw_site, cw_companyname)
               .SetPublicPrivateKey(public_key, private_key);
}

private static List<Invoice> getInvoices()
{
    var client = getApiClient();
    var invoicesApi = new InvoiceApi(client);
    var response = invoicesApi.GetInvoices();
    var invoices = response.GetResult<List<Invoice>>();
    foreach (var invoice in invoices)
    {
        Console.WriteLine(invoice.invoiceNumber);
    }
    return invoices;
}

Assuming you don't already have them or know what each part is:

  • Your App ID comes from here: https://developer.connectwise.com/Manage/Cookies
  • Your Connectwise Instance is hostname you use to connect
  • Your company is the "Company" field on the login screen
  • Your public and private keys are generated after creating an API Member (System->Members->API Members) and going to the "API Keys" tab for the new API Member.

On the following page, right hand side, there's a link to download the sample code.

You can use the tool SoapUI (enter link description here). This tool helps you to test all different WEB Interfaces.
