Accessing the MS Dynamics NAV Web Services

If your MS Dynamics NAV is hosted in an online Microsoft or Partner environment, you can access your MS Dynamics NAV Web Services directly over the internet (provided that the NAV Web Services have been exposed to the internet of cause).

In this case, set up an NS Dynamics NAV Web Service connector, delete/remove the RapidiConnector (there is a small 'Delete' icon on the RapidiConnector header line) and select "Windows" as Authentication Type and enter the external URL to the MS Dynamics NAV Web Services in the Server Connect field.


If the MS Dynamics NAV Web Services are not exposed to the internet, you can follow the description below to install the RapidiConnetor and set up access to the local MS Dynamics NAV Web Services.

Configuration in MS Dynamic NAV

    1. You need to use NTLM Authentication on the Web Service Server as we only support this Authentication method at the moment.
      • NAV2009: Please open the C:\Program Files\MS Dynamics NAV\60\Service\CustomSettings.config file and set the Key "WebServicesUseNTLMAuthentication" to "true". The Key "WebServiceSSLEnabled" should be "false".
      • NAV2013 or later: Open the Microsoft Dynamics NAV Administration program, select your server (default is DynamicsNAV70), press Edit, and check the "use NTLM Authentication". Ensure that the SOAP Services are enabled. Save and restart the server.
    2. In MS Dynamics NAV you also need to expose the Pages that you want to be able to access from RapidiOnline.
      • Go to C:\Program Files\MS Dynamics NAV\60\ RoleTailored Client, start Microsoft.Dynamics.Nav.Client.exe (NAV2009 default path) and navigate to Departments - Administration - IT Administration - General.
      • Select "Web Services" under Lists. Select New and specify "Page" as Object Type, select the ID of the page you want to expose (for example 21 for Customer card or 42 for Sales Order), specify a service name (e.g. Customer or SalesOrder) and check the Published box. Press OK.                                                                          *** Please Note (NAV2009): You have to restart the "Microsoft Dynamics NAV Business Web Services" service each time you change published services.
      • After this, you can go ahead and Read Design and start creating Transfers.
