On this page I found that Cvent integrates OOTB with D365, however when browsing through the available integrations within the application I come up with nothing. Can someone help me to find where this could be set up?
Microsoft Dynamics | Cvent App Marketplace
The integration with Microsoft Dynamics 365 is a custom integration. I have reached out to your account team and let them know that you were asking about this. They will be able to share more information about this integration.
