# Microsoft Dataverse

## 1 - Authenticating using oAuth

AuthScheme: Set this to **AzureAD**.

See [oAuth Authentication](https://docs.appstrategy.com/apprules-r-documentation/appendix/miscellaneous/oauth-authentication-azure-definition)

## 2 - Authenticating using MSI Authentication

If you are running Dataverse on an Azure VM, you can leverage Managed Service Identity (MSI) credentials to connect:

* AuthScheme: Set this to **AzureMSI**.

The MSI credentials will then be automatically obtained for authentication.

## 3 - Schema

Dataverse supports schema values of 'System' and 'Entities' and can be set using the Schema property.

Using 'System' for Schema property uses the Web API to query entities/tables.

Using 'Entities' for Schema property uses the **EntityDefinitions** entity set path and retrieves information about EntityMetadata EntityType entities/tables. This will often result in more user friendly names, though requires extra metadata requests.
