Before we send a custom event, we have to take a look at the Event Grid event schema:
[ { "topic": string, "subject": string, "id": string, "eventType": string, "eventTime": string, "data":{ object-unique-to-each-publisher }, "dataVersion": string, "metadataVersion": string }]
As you can see, it is a simple JSON array, containing many different events. Let's describe each field here:
- topic: This defines a full path to an event source (for example, Azure Blob Storage).
- subject: This defines a path to an event subject (so, in the case of publishing events from a resource group, this could be a full path to an Azure resource, or, in the case of Azure Blob Storage, this would be a Blob path).
- id: This is the unique identifier ...
