@Generated(value="jsii-pacmak/1.113.0 (build fc68b25)", date="2025-10-14T12:28:11.219Z") @Stability(Stable) public class CfnEventBusPolicy extends CfnResource implements IInspectable, IEventBusPolicyRef
Running PutPermission permits the specified AWS account or AWS organization to put events to the specified event bus .

Amazon EventBridge rules in your account are triggered by these events arriving to an event bus in your account.

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

To enable multiple AWS accounts to put events to your 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 EventBridge User Guide .

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

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.events.*;
 Object statement;
 CfnEventBusPolicy cfnEventBusPolicy = CfnEventBusPolicy.Builder.create(this, "MyCfnEventBusPolicy")
         .statementId("statementId")
         // the properties below are optional
         .action("action")
         .condition(ConditionProperty.builder()
                 .key("key")
                 .type("type")
                 .value("value")
                 .build())
         .eventBusName("eventBusName")
         .principal("principal")
         .statement(statement)
         .build();
