CreateEventSubscriptionCommand

Creates an event notification subscription. This action requires a topic ARN (Amazon Resource Name) created by either the Neptune console, the SNS console, or the SNS API. To obtain an ARN with SNS, you must create a topic in Amazon SNS and subscribe to the topic. The ARN is displayed in the SNS console.

You can specify the type of source (SourceType) you want to be notified of, provide a list of Neptune sources (SourceIds) that triggers the events, and provide a list of event categories (EventCategories) for events you want to be notified of. For example, you can specify SourceType = db-instance, SourceIds = mydbinstance1, mydbinstance2 and EventCategories = Availability, Backup.

If you specify both the SourceType and SourceIds, such as SourceType = db-instance and SourceIdentifier = myDBInstance1, you are notified of all the db-instance events for the specified source. If you specify a SourceType but do not specify a SourceIdentifier, you receive notice of the events for that source type for all your Neptune sources. If you do not specify either the SourceType nor the SourceIdentifier, you are notified of events generated from all Neptune sources belonging to your customer account.

Example Syntax

Use a bare-bones client and the command you need to make an API call.

import { NeptuneClient, CreateEventSubscriptionCommand } from "@aws-sdk/client-neptune"; // ES Modules import
// const { NeptuneClient, CreateEventSubscriptionCommand } = require("@aws-sdk/client-neptune"); // CommonJS import
const client = new NeptuneClient(config);
const input = { // CreateEventSubscriptionMessage
  SubscriptionName: "STRING_VALUE", // required
  SnsTopicArn: "STRING_VALUE", // required
  SourceType: "STRING_VALUE",
  EventCategories: [ // EventCategoriesList
    "STRING_VALUE",
  ],
  SourceIds: [ // SourceIdsList
    "STRING_VALUE",
  ],
  Enabled: true || false,
  Tags: [ // TagList
    { // Tag
      Key: "STRING_VALUE",
      Value: "STRING_VALUE",
    },
  ],
};
const command = new CreateEventSubscriptionCommand(input);
const response = await client.send(command);
// { // CreateEventSubscriptionResult
//   EventSubscription: { // EventSubscription
//     CustomerAwsId: "STRING_VALUE",
//     CustSubscriptionId: "STRING_VALUE",
//     SnsTopicArn: "STRING_VALUE",
//     Status: "STRING_VALUE",
//     SubscriptionCreationTime: "STRING_VALUE",
//     SourceType: "STRING_VALUE",
//     SourceIdsList: [ // SourceIdsList
//       "STRING_VALUE",
//     ],
//     EventCategoriesList: [ // EventCategoriesList
//       "STRING_VALUE",
//     ],
//     Enabled: true || false,
//     EventSubscriptionArn: "STRING_VALUE",
