Azure App Configuration as an Event Grid source

  • Article

This article provides the properties and schema for Azure App Configuration events. For an introduction to event schemas, see Azure Event Grid event schema. It also gives you a list of quick starts and tutorials to use Azure App Configuration as an event source.

Available event types

Event Grid uses event subscriptions to route event messages to subscribers. Azure App Configuration emits the following event types:

Event type Description
Microsoft.AppConfiguration.KeyValueModified Raised when a key-value is created or replaced.
Microsoft.AppConfiguration.KeyValueDeleted Raised when a key-value is deleted.
Microsoft.AppConfiguration.SnapshotCreated Raised when a snapshot is created.
Microsoft.AppConfiguration.SnapshotModified Raised when a snapshot is modified.

Event schema

An event has the following top-level data:

Property Type Description
source string Full resource path to the event source. This field isn't writeable. Event Grid provides this value.
subject string Publisher-defined path to the event subject.
type string One of the registered event types for this event source.
time string The time the event is generated based on the provider's UTC time.
id string Unique identifier for the event.
data object App Configuration event data.
specversion string CloudEvents schema specification version.

The data object has the following properties:

Key-value event

Property Type Description
key string The key of the key-value that was modified or deleted.
label string The label, if any, of the key-value that was modified or deleted.
etag string For KeyValueModified the etag of the new key-value. For KeyValueDeleted the etag of the key-value that was deleted.
syncToken string The sync token representing the server state after the key-value event.

Snapshot event

Property Type Description
name string The name of the snapshot that was created or modified.
etag string For SnapshotCreated the etag of the new snapshot. For SnapshotModified the etag of the snapshot that was modified.
syncToken string The sync token representing the server state after the snapshot event.

Example event

The following example shows the schema of a key-value modified event:

  },
  "type": "Microsoft.AppConfiguration.KeyValueModified",
  "time": "2019-05-31T20:05:03Z",
  "specversion": "1.0"
}]

The following example shows the schema of a key-value deleted event:

[{
  "id": "84e17ea4-66db-4b54-8050-df8f7763f87b",
  "source": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testrg/providers/microsoft.appconfiguration/configurationstores/contoso",

  "data": {
    "key": "Foo",
    "label": "FizzBuzz",
    "etag": "FnUExLaj2moIi4tJX9AXn9sakm0"
  },
  "type": "Microsoft.AppConfiguration.KeyValueDeleted",
  "time": "2019-05-31T20:05:03Z",
  "specversion": "1.0"
}]

The following example shows the schema of a snapshot created event:

[{
  "source": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testrg/providers/microsoft.appconfiguration/configurationstores/contoso",
  "subject": "https://contoso.azconfig.io/kvsnapshots/Foo",
  "type": "Microsoft.AppConfiguration.SnapshotCreated",
  "time": "2023-09-02T20:05:03.0000000Z",
  "id": "84e17ea4-66db-4b54-8050-df8f7763f87b",
  "data": {

    "syncToken": "zAJw6V16=Njo1IzUxNjQ2NzM=;sn=5164673"
  },
  "specversion": "1.0"
}]

The following example shows the schema of a snapshot modified event:

[{
  "source": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testrg/providers/microsoft.appconfiguration/configurationstores/contoso",
