What configuration/component/change is needed in SAP Business One server to connect SAP Business One with an eCommerce or a CRM solution?

For APPSeCONNECT’s SAP Business One Integration, we need DI server license/DI API installed in the SAP server. DI server provides greater performance than DI API and DI server is recommended by SAP, but DI server license has separate license cost and this needs to be purchased from your SAP partner. Also, APPSeCONNECT is compatible with SAP Business One 8.8 and above.
