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.

Request parameters

Parameter	Type	Required	Description	Example
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate a token, but you must make sure that the token is unique among different requests. The client token can contain only ASCII characters. Note If you do not specify this parameter, the system automatically uses the value of RequestId as the client token. The value of RequestId is different for each API request.	02fb3da4-130e-11e9-8e44-0016e04115b

It must be 1 to 100 characters in length, and can contain letters, digits, and the following characters: ~!`@#$%^&()_-+={}[]\|;:',.<>/? If you do not specify a pre-shared key, the system generates a random 16-character string as the pre-shared key. You can call the DescribeVpnConnection operation to query the pre-shared key that is generated by the system. Note* The pre-shared key that is configured for the tunnel and the tunnel peer must be the same. Otherwise, the system cannot establish the tunnel.	123456****
