Event Grid subscription schema

Raksts
03/20/2023

To create an Event Grid subscription, you send a request to the Create Event subscription operation. Use the following format:

PUT /subscriptions/{subscription-id}/resourceGroups/{group-name}/providers/{resource-provider}/{resource-type}/{resource-name}/Microsoft.EventGrid/eventSubscriptions/{event-type-definitions}?api-version=2018-01-01

For example, to create an event subscription for a storage account named examplestorage in a resource group named examplegroup, use the following format:

PUT /subscriptions/{subscription-id}/resourceGroups/examplegroup/providers/Microsoft.Storage/storageaccounts/examplestorage/Microsoft.EventGrid/eventSubscriptions/{event-type-definitions}?api-version=2018-01-01

The Event Subscription name must be 3-64 characters in length and can only contain a-z, A-Z, 0-9, and "-". The article describes the properties and schema for the body of the request.
