Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

DeadLetterConfig

Configuration details of the Amazon SQS queue for EventBridge to use as a dead-letter queue (DLQ).

For more information, see Using dead-letter queues to process undelivered events in the EventBridge User Guide.

Type: DeadLetterConfig object

Required: No

Description

The event bus description.

Type: String

Length Constraints: Maximum length of 512.

Required: No

EventSourceName

If you are creating a partner event bus, this specifies the partner event source that the new event bus will be matched with.

Type: String

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

Pattern: aws\.partner(/[\.\-_A-Za-z0-9]+){2,}

Required: No

KmsKeyIdentifier

The identifier of the AWS KMS customer managed key for EventBridge to use, if you choose to use a customer managed key to encrypt events on this event bus. The identifier can be the key Amazon Resource Name (ARN), KeyId, key alias, or key alias ARN.

If you do not specify a customer managed key identifier, EventBridge uses an AWS owned key to encrypt events on the event bus.

For more information, see Identify and view keys in the AWS Key Management Service Developer Guide.

Note

Schema discovery is not supported for event buses encrypted using a customer managed key. EventBridge returns an error if:

You call CreateDiscoverer on an event bus set to use a customer managed key for encryption.
You call UpdatedEventBus to set a customer managed key on an event bus with schema discovery enabled.

To enable schema discovery on an event bus, choose to use an AWS owned key. For more information, see Encrypting events in the Amazon EventBridge User Guide.

Important

If you have specified that EventBridge use a customer managed key for encrypting the source event bus, we strongly recommend you also specify a customer managed key for any archives for the event bus as well.

For more information, see Encrypting archives in the Amazon EventBridge User Guide.

Type: String

Length Constraints: Maximum length of 2048.

Pattern: ^[a-zA-Z0-9_\-/:]*$

Required: No

LogConfig

The logging configuration settings for the event bus.

For more information, see Configuring logs for event buses in the EventBridge User Guide.

Required: No

Name

The name of the new event bus.

Custom event bus names can't contain the / character, but you can use the / character in partner event bus names. In addition, for partner event buses, the name must exactly match the name of the partner event source that this event bus is matched to.

You can't use the name default for a custom event bus, as this name is already used for your account's default event bus.

Type: String

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

Pattern: [/\.\-_A-Za-z0-9]+

Required: Yes

Tags
