Authorize partner to create a partner topic

You must grant your consent to the partner to create partner topics in a resource group that you designate. This authorization has an expiration time. It's effective for the time period you specify between 1 to 365 days.

1. Sign in to the Azure portal.

2. In the search bar at the top, enter Partner Configurations, and select Event Grid Partner Configurations under Services in the results.

3. On the Event Grid Partner Configurations page, select Create Event Grid partner configuration button on the page (or) select + Create on the command bar.

   

4. On the Create Partner Configuration page, do the following steps:

   1. In the Project Details section, select the Azure subscription and the resource group where you want to allow the partner to create a partner topic.

   2. In the Partner Authorizations section, specify a default expiration time for partner authorizations defined in this configuration.

   3. To provide your authorization for a partner to create partner topics in the specified resource group, select + Partner Authorization link.

      

5. On the Add partner authorization to create resources page, you see a list of verified partners. A verified partner is a partner whose identity has been validated by Microsoft. Follow these steps to authorize Auth0 to create a partner topic.

   1. Select the verified partner (Auth0, SAP, Tribal Group, or Microsoft Graph API) from the list of verified partners.

   2. Specify authorization expiration time.

   3. select Add.

      

      Important

      Your partner won't be able to create resources (partner topics) in your Azure subscription after the authorization expiration time.

6. Back on the Create Partner Configuration page, verify that the partner is added to the partner authorization list at the bottom.

7. Select Review + create at the bottom of the page.

8. On the Review page, review all settings, and then select Create to create the partner registration.

Enable events to flow to your partner topic

SAP's capability to send events to Azure Event Grid is available through SAP's beta program. Using this program, you can let SAP know about your desire to have your S4/HANA events available on Azure. You can find the SAP's announcement of this new feature here. Through SAP's Beta program, you'll be provided with the documentation on how to configure your SAP S4/HANA system to flow events to Event Grid.

SAP's BETA program started in October 2022 and will last a couple of months. Thereafter, the feature will be released by SAP as a generally available (GA) capability. Event Grid's capability to receive events from a partner, like SAP, is already a GA feature.

Activate a partner topic

1. In the search bar of the Azure portal, search for and select Event Grid Partner Topics.

2. On the Event Grid Partner Topics page, select the partner topic in the list.

   

3. Review the activate message, and select Activate on the page or on the command bar to activate the partner topic before the expiration time mentioned on the page.

   

4. Confirm that the activation status is set to Activated and then create event subscriptions for the partner topic by selecting + Event Subscription on the command bar.

   

Subscribe to events

First, create an event handler that will handle events from the partner. For example, create an event hub, Service Bus queue or topic, or an Azure function. Then, create an event subscription for the partner topic using the event handler you created.

Create an event handler

To test your partner topic, you'll need an event handler. Go to your Azure subscription and spin up a service that's supported as an event handler such as an Azure Function. For an example, see Event Grid Viewer sample that you can use as an event handler via webhooks.

Subscribe to the partner topic

Subscribing to the partner topic tells Event Grid where you want your partner events to be delivered.

1. In the Azure portal, type Event Grid Partner Topics in the search box, and select Event Grid Partner Topics.

2. On the Event Grid Partner Topics page, select the partner topic in the list.

   

3. On the Event Grid Partner Topic page for the partner topic, select + Event Subscription on the command bar.

   

4. On the Create Event Subscription page, do the following steps:

   1. Enter a name for the event subscription.

   2. For Filter to Event Types, select types of events that your subscription will receive.

   3. For Endpoint Type, select an Azure service (Azure Function, Storage Queues, Event Hubs, Service Bus Queue, Service Bus Topic, Hybrid Connections. etc.), or webhook.

   4. Click the Select an endpoint link. In this example, let's use Azure Event Hubs destination or endpoint.

      

   5. On the Select Event Hub page, select configurations for the endpoint, and then select Confirm Selection.

      

   6. Now on the Create Event Subscription page, select Create.
