From version 3.0.2076 we have improved the Dynamics connector, please see our updated documentation here.
Data Sync has a provider that will connect to your Dynamics 365 Online enabling you to import, migrate and export data. To connect go to 'Connect Datasource' in either the source (Data Source A) or the target (Data Source B), and select the Dynamics 365 connector.
The following video shows how to connect to Dynamics 365 with Data Sync, store the connection in the Connection Library and then use that connection to load data from a SQL table into Dynamics.
This is the URL to your Dynamics 365 Organisation Service SOAP\WCF service.
This URL will be similar to:
https://orgname.api.crm4.dynamics.com/XRMServices/2011/Organization.svc to get your organisation URL go to
Settings->Customizations->Developer Info in Dynamics 365.
In the case of Dynamics 365 Online, set this to 'Federated'.
Enter any required credentials.
If you have entered the previous information correctly, you should be able to use the Entity drop down menu to select an entity within the Dynamics 365 system.
If your using Azure AD multi-factor-authentication you will need to get an App Password from your Azure AD account to use with Data Sync. After creating a new app password wait 5 minutes or so for the password to be ready in Dynamics 365.
