Changes (request)
{'Condition': {'Key': 'string', 'Type': 'string', 'Value': 'string'}}

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.

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

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

type Principal


param Principal


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.

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 .

param Condition
