DescribeSubscriber - Amazon EventBridge Custom Event Bus

DescribeSubscriber

Returns the full configuration and state of a subscriber.

Request Parameters

SubscriberArn

The Amazon Resource Name (ARN) that uniquely identifies a subscriber.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1011.

Pattern: arn:aws(-[a-z0-9]+)*:events:[a-z][a-z0-9]*(-[a-z0-9]+)*:([0-9]{12}):subscriber\/[A-Za-z0-9][\.\-_A-Za-z0-9]{0,255}\/[a-z0-9]{25}

Required: Yes

Response Elements

The following elements are returned by the service.

BatchConfiguration

Batching configuration for a subscriber.

Type: BatchConfiguration object

CreationTime

The time the subscriber was created.

Type: Timestamp

Description

Free-text description. Used by every resource type that has one: event buses, subscribers, and event sources.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 512.

Pattern: [^\u0000-\u001F\u007F-\u009F\u2028\u2029]*(?![\s\S]).*

EventBusArn

The Amazon Resource Name (ARN) that uniquely identifies an event bus.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1011.

Pattern: arn:aws(-[a-z0-9]+)*:events:[a-z][a-z0-9]*(-[a-z0-9]+)*:([0-9]{12}):event-busv2\/[A-Za-z0-9][\.\-_A-Za-z0-9]{0,255}\/[a-z0-9]{25}

FilterConfiguration

Configuration for filtering events delivered to a subscriber. On CreateSubscriber, Filters is required and must contain at least one Filter with a non-empty Pattern. On UpdateSubscriber, an empty FilterConfiguration:{} clears the existing filter. Any non-empty shape (including {Language:X} without Filters) must contain a valid Filters list — same contract as CreateSubscriber. A non-empty Filters list overwrites; an omitted FilterConfiguration preserves existing state. All Filters are implicitly ANDed — an event must match every Filter to be delivered.

Type: FilterConfiguration object

InvokeConfiguration

Configuration for how the subscriber invokes its target.

Type: InvokeConfiguration object

LastModifiedTime

The time the subscriber was last modified.

Type: Timestamp

LogConfiguration

Log configuration for a subscriber.

Type: LogConfiguration object

Name

Name of a subscriber. The first character must be alphanumeric; the remaining characters may also include '.', '-', and '_'.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Pattern: [A-Za-z0-9][\.\-_A-Za-z0-9]*

OnFailureConfiguration

On-failure configuration: where a failed delivery is sent. Shared by the subscriber and the EventSource.

Type: OnFailureConfiguration object

PointInTimeConfiguration

Point-in-time configuration for a subscriber. Only applicable when StartingPosition is POINT_IN_TIME.

Type: PointInTimeConfiguration object

RetryPolicy

Retry policy for a subscriber.

Type: RetryPolicy object

Revoked

True when the bus owner has revoked this subscriber. Present only when true, so an absent member means the subscriber is not revoked. Revocation is terminal: it never returns to false. Mutating operations on a revoked subscriber fail with InvalidStateException, except DeleteSubscriber, which stays available so a revoked subscriber can still be cleaned up.

Type: Boolean

StartingPosition

Starting position for a subscriber.

Type: String

Valid Values: LATEST | POINT_IN_TIME

State

Customer-controlled run state of a subscriber, set on create or update. Distinct from the bus lifecycle vocabulary, where ACTIVE means "provisioned and healthy". Delivery requires State RUNNING on a subscriber that is not revoked.

Type: String

Valid Values: RUNNING | STOPPED

SubscriberArn

The Amazon Resource Name (ARN) that uniquely identifies a subscriber.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1011.

Pattern: arn:aws(-[a-z0-9]+)*:events:[a-z][a-z0-9]*(-[a-z0-9]+)*:([0-9]{12}):subscriber\/[A-Za-z0-9][\.\-_A-Za-z0-9]{0,255}\/[a-z0-9]{25}

Transformer

Transformer configuration for a subscriber.

Type: Transformer object

Type

Delivery ordering mode of a subscriber: FIFO delivers events in order within an event group; UNORDERED delivers without an ordering guarantee.

Type: String

Valid Values: FIFO | UNORDERED
