[ aws . events ]



Running PutPermission permits the specified AWS account or AWS organization to put events to your account's default event bus . CloudWatch Events rules in your account are triggered by these events arriving to your default event bus.

For another account to send events to your account, that external account must have a CloudWatch Events rule with your account's default event bus as a target.

To enable multiple AWS accounts to put events to your default event bus, run PutPermission once for each of these accounts. Or, if all the accounts are members of the same AWS organization, you can run PutPermission once specifying Principal as "*" and specifying the AWS organization ID in Condition , to grant permissions to all accounts in that organization.

If you grant permissions using an organization, then accounts in that organization must specify a RoleArn with proper permissions when they use PutTarget to add your account's event bus as a target. For more information, see Sending and Receiving Events Between AWS Accounts in the Amazon CloudWatch Events User Guide .

The permission policy on the default event bus cannot exceed 10 KB in size.

--action (string)

The action that you are enabling the other account to perform. Currently, this must be events:PutEvents .

--principal (string)

The 12-digit AWS account ID that you are permitting to put events to your default event bus. Specify "*" to permit any account to put events to your default event bus.

If you specify "*" without specifying Condition , avoid creating rules that may match undesirable events. To create more secure rules, make sure that the event pattern for each rule contains an account field with a specific account ID from which to receive events. Rules with an account field do not match any events sent from other accounts.

--statement-id (string)

An identifier string for the external account that you are granting permissions to. If you later want to revoke the permission for this external account, specify this StatementId when you run RemovePermission .

--condition (structure)

This parameter enables you to limit the permission to accounts that fulfill a certain condition, such as being a member of a certain AWS organization. For more information about AWS Organizations, see What Is AWS Organizations in the AWS Organizations User Guide .

If you specify Condition with an AWS organization ID, and specify "*" as the value for Principal , you grant permission to all the accounts in the named organization.

The Condition is a JSON string which must contain Type , Key , and Value fields.

Shorthand Syntax:


JSON Syntax:

  "Type": "string",
  "Key": "string",
  "Value": "string"

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
