# CfnEventSubscriptionProps

Properties for defining a `CfnEventSubscription`.

- Source: Generated code

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_dms as dms } from 'aws-cdk-lib';
const cfnEventSubscriptionProps: dms.CfnEventSubscriptionProps = {
  snsTopicArn: 'snsTopicArn',

  // the properties below are optional
  enabled: false,
  eventCategories: ['eventCategories'],
  sourceIds: ['sourceIds'],
  sourceType: 'sourceType',
  subscriptionName: 'subscriptionName',
  tags: [{
    key: 'key',
    value: 'value',
  }],
};
```

## Properties

- `enabled`: boolean | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) — Indicates whether to activate the subscription.

  If you don't specify this property, CloudFormation activates the subscription.

- `eventCategories`: string[] — A list of event categories for a source type that you want to subscribe to.

  If you don't specify this property, you are notified about all event categories. For more information, see [Working with Events and Notifications](https://docs.aws.amazon.com//dms/latest/userguide/CHAP_Events.html) in the *AWS DMS User Guide* .

- `snsTopicArn`: string (required) — The Amazon Resource Name (ARN) of the Amazon SNS topic created for event notification.

  The ARN is created by Amazon SNS when you create a topic and subscribe to it.

- `sourceIds`: string[] — A list of identifiers for which AWS DMS provides notification events.

  If you don't specify a value, notifications are provided for all sources.

  If you specify multiple values, they must be of the same type. For example, if you specify a database instance ID, then all of the other values must be database instance IDs.

- `sourceType`: string — The type of AWS DMS resource that generates the events.

  For example, if you want to be notified of events generated by a replication instance, you set this parameter to `replication-instance` . If this value isn't specified, all events are returned.

  *Valid values* : `replication-instance` | `replication-task`

- `subscriptionName`: string — The name of the AWS DMS event notification subscription.

  This name must be less than 255 characters.

- `tags`: [CfnTag](/cdk/api/v2/docs/aws-cdk-lib.CfnTag.html)[] — One or more tags to be assigned to the event subscription.
