We provide a connector to connect Sitecore to your CRM. The two supported CRMs are Microsoft Dynamics CRM and Salesforce CRM. We have also prepared a page for Sitecore 9.3 regarding the installation procedure of the connector.
The framework is a tool called Data Exchange Framework that works with Sitecore and connectors. Based on this, we provide connectors for Dynamics CRM and Salesforce CRM so that they can be integrated via web services.
We have also prepared a reference video regarding the installation process and integration with Salesforce.
