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
EcrId	string	Yes	The ID of the Express Connect Router instance.	ecr-gny3gqp41n7vrrn5iz
ChildInstanceId	string	Yes	The ID of the virtual border router (VBR) instance.	vbr-t4n6xu2d5q0iaad1yl4le
ChildInstanceType	string	Yes	The type of the child instance. Valid value: VBR: a VBR.	VBR
Description	string	No	The description of the child instance. The description must be 0 to 128 characters in length.	test
DryRun	boolean	No	Specifies whether to perform a dry run. Valid values: true: Performs a dry run to check the request without modifying any resources. false (default): Sends a normal request.	false
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. This token is generated by the client and must be unique among different requests. The token can contain only ASCII characters. You can generate a token from your client, but you must ensure that the token is unique across different requests. The token can contain only ASCII characters. Note If you do not specify this parameter, the system uses the RequestId of the request as the ClientToken. The RequestId may be different for each request.	02fb3da4-130e-11e9-8e44-00****

Response elements

HttpStatusCode	integer	The HTTP status code.	200
DynamicCode	string	The dynamic error code.	IllegalParamFormat.EcrId
DynamicMessage	string	The dynamic error message that is used to replace the `%s` placeholder in the error message. Note For example, if the error message is The Value of Input Parameter %s is not valid and this parameter returns DtsJobId, this means the DtsJobId parameter that you specified is invalid.	The param format of EcrId **** is illegal.
AccessDeniedDetail	string	The details about the access denial.	Authentication is failed for ****
