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.

Event schema

An event has the following top-level data:

Property Type Description
topic 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.
eventType string One of the registered event types for this event source.
eventTime 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.
dataVersion string The schema version of the data object. The publisher defines the schema version.
metadataVersion string The schema version of the event metadata. Event Grid defines the schema of the top-level properties. Event Grid provides this value.

The data object has the following properties:

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.

Example event

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

[{
  "id": "84e17ea4-66db-4b54-8050-df8f7763f87b",
  "topic": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testrg/providers/microsoft.appconfiguration/configurationstores/contoso",
  "subject": "https://contoso.azconfig.io/kv/Foo?label=FizzBuzz",
  "data": {
    "key": "Foo",
    "label": "FizzBuzz",
    "etag": "FnUExLaj2moIi4tJX9AXn9sakm0"
  },
  "eventType": "Microsoft.AppConfiguration.KeyValueModified",
  "eventTime": "2019-05-31T20:05:03Z",
  "dataVersion": "1",
  "metadataVersion": "1"
}]

The schema for a key-value deleted event is similar:

[{
  "id": "84e17ea4-66db-4b54-8050-df8f7763f87b",
  "topic": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testrg/providers/microsoft.appconfiguration/configurationstores/contoso",
  "subject": "https://contoso.azconfig.io/kv/Foo?label=FizzBuzz",
  "data": {
    "key": "Foo",
    "label": "FizzBuzz",
    "etag": "FnUExLaj2moIi4tJX9AXn9sakm0"
  },
  "eventType": "Microsoft.AppConfiguration.KeyValueDeleted",
  "eventTime": "2019-05-31T20:05:03Z",
  "dataVersion": "1",
  "metadataVersion": "1"
}]
