Microsoft Entra ID authentication and Azure Event Hubs connector

In order to use Microsoft Entra ID authentication, the account that is being used needs to be assigned an specific role assignment, for more information, visit Assign an Azure role for access rights - Azure Event Hubs:

Managed identity authentication and Azure Event Hubs connector

Currently, managed identity authentication is only supported in Logic Apps. Follow steps below to use it to connect to your Azure Event Hubs:

1. Create an Azure Managed Identity
2. Give identity access to Azure Event Hubs resources. For more details, visit Assign an Azure role for access rights - Azure Event Hubs
3. If using a user-assigned identity, associate the logic app with the managed identity
   1. Navigate to the Logic App that will use the managed identity.
   2. Under Settings section of the blade, click Identity
   3. Go to User assigned tab and click on Add
   4. Select the managed identity to be used and click on Add

For more information about authenticating with managed identities in Logic Apps visit Authenticate access to Azure resources using managed identities in Azure Logic Apps

Known issues and limitations with triggers

• Trigger polling occurs one partition at-a-time. This can potentially cause increased delays as partition count grows.

Creating a connection

The connector supports the following authentication types:

Access Key	Provide connection string to access your Azure Event Hubs.	All regions except Azure Government and Department of Defense (DoD) in Azure Government and US Government (GCC) and US Government (GCC-High)	Not shareable
