azure event grid example

Now, let’s use the Azure Event Grid client library to send and receive some CloudEvents! These categories, or topics, can then be used by event handlers to subscribe to the events that they are interested in. There are services that do similar things that have been around for years, like Azure Logic Apps and Azure Service Bus Queues and Topics. When using a custom topic, events must always be published in an array. For HTTP webhook event handlers, the event is retried until the handler returns a status code of 200 – OK. For Azure Storage Queue, the events are retried until the Queue service successfully processes the message push into the queue. This is a similar mechanism as Topics in the Azure Service Bus. For example, create an application topic to send your app’s event data to Event Grid and take advantage of its reliable delivery, advanced routing, and direct integration with Azure. The following example shows the properties that are used by all event publishers: For example, the schema published for an Azure Blob storage event is: The SaaS provider exposes a topic type, a partner topic, that subscribers use to consume events.
