Running PutPermission permits the specified AWS account or AWS
organization to put events to the specified event bus. Amazon
EventBridge (CloudWatch Events) rules in your account are triggered by
these events arriving to an event bus in your account.
cloudwatchevents_put_permission(EventBusName, Action, Principal,
StatementId, Condition)The event bus associated with the rule. If you omit this, the default event bus is used.
[required] The action that you are enabling the other account to perform.
Currently, this must be events:PutEvents.
[required] 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.
[required] 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.
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.
svc$put_permission(
EventBusName = "string",
Action = "string",
Principal = "string",
StatementId = "string",
Condition = list(
Type = "string",
Key = "string",
Value = "string"
)
)
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 default event bus cannot exceed 10 KB in size.
