RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
EventBusName	string	Yes	The name of the event bus.	MyEventBus
Description	string	No	The description of the event rule.	Filter rule for Simple Message Queue (formerly MNS) (SMQ)
RuleName	string	Yes	The name of the event rule.	SMQRule
Status	string	No	The status of the event rule. Valid values: `ENABLE`: The rule is enabled. This is the default value. `DISABLE`: The rule is disabled.	ENABLE
FilterPattern	string	Yes	The event pattern, in JSON format. Supported pattern types are `stringEqual` and `stringExpression`. Each field can contain a maximum of five expressions in a map structure.	{ "source": [ { "prefix": "acs." } ], "type": [ { "prefix": "oss:ObjectReplication" } ], "subject": [ { "prefix": "acs:oss:cn-hangzhou:123456789098****:my-movie-bucket/", "suffix": ".txt" } ] }
EventTargets	array<object>	No	A list of event targets.
	array<object>	No	An event target.
Id	string	Yes	The custom ID of the event target.	Mlm123456JHd2RsRoKw
Type	string	Yes	The type of the event target. For more information, see Event target parameters.	acs.mns.queue
Endpoint	string	No	The delivery endpoint for events.	acs:mns:cn-hangzhou:123456789098****:queues/myqueue
PushRetryStrategy	string	No	The push retry strategy. Valid values: `BACKOFF_RETRY`: A backoff retry strategy where the system makes three retry attempts at random intervals of 10 to 20 seconds. `EXPONENTIAL_DECAY_RETRY`: An exponential decay retry strategy where the system makes 176 retry attempts over 24 hours. The interval starts at 1 second and doubles with each of the first 10 attempts (up to 512 seconds). Subsequent retries occur every 512 seconds.	BACKOFF_RETRY
DeadLetterQueue	object	No	The dead-letter queue. If an event fails to be processed or exceeds the retry limit, it is sent to the dead-letter queue. Supported services for the dead-letter queue include Message Queue for Apache RocketMQ, Message Service (MNS), Message Queue for Apache Kafka, and EventBridge event buses.
Arn	string	No	The Alibaba Cloud Resource Name (ARN) of the dead-letter queue. Events that fail to be processed or exceed the retry limit are sent to this ARN. Supported services for this parameter include Message Service (MNS) and Message Queue for Apache RocketMQ.	acs:mns:cn-hangzhou:123456789098****:/queues/deadletterqueue
Network	string	No	The network type.
VpcId	string	No	The VPC ID.
VSwitchIds	string	No	The vSwitch ID.
SecurityGroupId	string	No	The security group ID.
ErrorsTolerance	string	No	The fault tolerance policy. Valid values: `ALL`: Enables fault tolerance. Execution continues even if an error occurs. After all retry attempts fail, the event is sent to the dead-letter queue (if configured) or discarded. `NONE`: Disables fault tolerance. Execution is blocked if an error occurs and all retry attempts fail.	ALL
ParamList	array<object>	No	The parameters for the event target.
	object	No	A single parameter for the event target.
ResourceKey	string	No	The name of the target parameter. For more information, see Limits.	body
Form	string	No	The format of the event target parameter. For more information, see Limits.	TEMPLATE
Value	string	No	The value of the event target parameter.	{"key"="value"}
Template	string	No	The template for the event target parameter.	The value of ${key} is ${value}!
ConcurrentConfig	object	No	The concurrency control configuration.
Concurrency	integer	No	The maximum number of concurrent executions for the event target.	2
