# Sage 300

Kindly confirm the version of the Sage 300 ERP system. For the Sage 300 ERP version that is 2018 Version and earlier; we would need the SData Web.

For security, you can install the SSL certificate and whitelist the below IP to your firewall:

* We would require SData Web-service URL to be mapped to a domain or a sub-domain in order to be accessible over the web. The domain or sub-domain would be connected/mapped using SSL (for secured connection) to the port of a system that connects to the Sage 300 ERP SData Web-service URL. **For e.g.** \[https\://%3c%3cDOMAIN]https\://<\<DOMAIN NAME>>/ SDataServlet/sdata/sager     p/accpac/SAMINC/ARCustomersFinder  (Where SAMINC = your Sage company Database)
* The IT team needs to have an internet domain (or sub-domain) name that will point to the specific port (443) of SData on the system.
* SSL Certificate should be installed for the domain (or sub-domain) for making the connection secure. It should not self-signed and should be signed and installed from a valid third-party vendor.
