Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Operation	Access level	Resource type	Condition key	Associated operation

Request parameters

Parameter	Type	Required	Description	Example
ChangeOrderId	string	Yes	76fa5c0-9ebb-4bb4-b383-1f885447****	76fa5c0-9ebb-4bb4-b383-1f885447****

	object
RequestId	string	The ID of the request.	91F93257-7A4A-4BD3-9A7E-2F6EAE6D****
Message	string	The returned message.	success
TraceId	string	The ID of the trace. It is used to query the details of a request.	0a98a02315955564772843261e****
Data	object	The details of the change order.
Status	integer	The status of the change order. Valid values: 0: The change order is being prepared. 1: The change order is being executed. 2: The change order was executed. 3: The change order could not be executed. 6: The change order was terminated. 8: The execution process is pending. You must manually determine the release batch. 9: The execution process is pending. SAE will automatically determine the release batches. 10: The execution failed due to a system exception. 11: The change order is pending approval. 12: The change order is approved and is pending execution.	2
