The AccountRight API is the service that needs to be running in order to connect from an external application. 

To verify that the service is running, open the Task Manager and view the Services tab. Make sure that the following services are running:

  • MYOBAPIService
  • MYOB AccountRight Server 2016.3 (or the one corresponding to the version of MYOB AccountRight you have)
  • MYOB AccountRight Library
  • MYOB AccountRight Server Locator


You may use the following link from the MYOB online guide on how to install the API, however this still has images from the version up until 2016.2 with the icon on the task bar no longer available in 2016.3 but the installation process is similar.

A way to test is by opening this URL (http://localhost:8080/AccountRight) on your browser. If it shows the company files then it can be a good sign the API is active.

Note: Replace localhost by the actual domain name or IP address of your server. You can also replace 8080 by the port number if you are using a different one.

If you had a previous version of MYOB installed on your computer, uninstall it and then reinstall 2016.3 just to make sure it is not carrying anything over from the previous version. Also, please go through recommendations mentioned the link above.
