The EXO Business API uses the MYOB LiveRelay technology to connect to an on premise database from a remote location. The MYOB LiveRelay is included as an optional service when installing the EXO Business API.
The MYOB LiveRelay service is installed using the EXO Business Services Setup Wizard. This install wizard is supplied by MYOB, packaged with the main product installer for EXO Business.
Run the MYOB EXO Business Services Setup Wizard, and when asked which features you want to install, make sure that the API Service option is enabled.
After installation, the Live Relay service must be set up for each EXO Business database connection, using the MYOB EXO Business Service Configuration utility. This utility can be run immediately after installation, or you can open it from the EXO API install directory at any time.
