Amazon CloudWatch Events

Running PutPermission permits the specified AWS account 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.
