Technical Considerations
The integration between Maconomy and Deltek CRM communicates via HTTPS over port 443.
If your instance of Deltek CRM and/or Maconomy is hosted in the Deltek cloud, you will not need to make any changes to your system to support the integration. However, if you have either Deltek CRM or Maconomy deployed on premises with the other product hosted in the Deltek cloud, you will need to ensure that your on-premise application server for either product has port 443 open to the internet so that it can properly communicate with the cloud-based application server.
In addition, if your network security infrastructure is employing any sort of URL-based traffic filtering, you will need to ensure that you configure that filter to allow all traffic from/to the URL used to access the cloud-based product.
If both Deltek CRM and Maconomy are deployed on premises, you will only need to ensure that port 443 is open between both application servers via your internal network and that you are not filtering the URL used to access either application.
