Synergy Resources requires a dedicated Web Services application installed on Internet Information Services (IIS) of an application server (not the VISUAL Database Server). 
The new server will need to be accessible from the internet, but only from a select set of IP addresses this will vary by project. 
We typically recommend to customers that this new Web Services API Server be placed in the DMZ of your network, but it must also have local network access to the VISUAL database server.




Once the server is provisioned, the Synergy Resources Systems Architect will require Remote Desktop Access (either 
direct, via a VPN connection, or other customer provided remote session). The Systems Architect will install Synergy’s 
Distributed ERP, configure the new web application, and test connections locally. Once SSL certificates are available 
and firewall rules are created, the Systems Architect will also test access from the integration platform. 

The solution also requires an A Record created in your DNS so an SSL certificate can be applied to IIS on this new 
server. This Host record can be something like visualapi  Public IP address. The certificate request can be made 
through IIS once the server is provisioned unless an SSL certificate is already available.
The new or existing SSL certificate (or a wildcard certificate) for the host’s name will allow the integration platform 
to communicate with the Web Services API via the secure URL. The Web Services API link would be similar to:
For firewall rules, direct https traffic on Port 443 to Port 443 on that server. You can choose to use another port if desired. 
The port will also need to be opened on the server’s Windows Firewall Rules.
