CreateIpv4Gateway - Virtual Private Cloud - Alibaba Cloud Documentation Center

Creates an IPv4 gateway.

Operation description

CreateIpv4Gateway is an asynchronous operation. After you send a request, the system returns a request ID and runs the task in the background. You can call the GetIpv4GatewayAttribute operation to query the status of an IPv4 gateway:
- If the IPv4 gateway is in the Creating state, the IPv4 gateway is being created.
- If the IPv4 gateway is in the Created state, the IPv4 gateway is created.
You cannot repeatedly call the CreateIpv4Gateway operation to create IPv4 gateways in a virtual private cloud (VPC) within the specified period of time.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

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.

Request parameters

Parameter	Type	Required	Description	Example
Ipv4GatewayName	string	No	The name of the IPv4 gateway. The name must be 1 to 128 characters in length, and cannot start with `http://` or `https://`.	ipv4
Ipv4GatewayDescription	string	No	The description of the IPv4 gateway. The description must be 1 to 256 characters in length and cannot start with `http://` or `https://`.	test
VpcId	string	Yes	The ID of the VPC where you want to create the IPv4 gateway. You can create only one IPv4 gateway in a VPC.	vpc-5tss06uvoyps5xoya****
DryRun	boolean	No	Specifies whether to perform a dry run. Valid values: true: performs a dry run. The system checks the required parameters, request syntax, and limits. If the request fails the dry run, an error message is returned. If the request passes the dry run, the `DryRunOperation` error code is returned. false (default): performs a dry run and sends the request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed.	false
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must make sure that it is unique among different requests. ClientToken can contain only ASCII characters. Note If you do not set this parameter, the system sets ClientToken to the value of RequestId. The value of RequestId for each API request is different.	123e4567-e89b-12d3-a456-426655440000
RegionId	string	Yes	The ID of the region where you want to create the IPv4 gateway. You can call the DescribeRegions operation to query the most recent region list.	ap-southeast-6
ResourceGroupId	string	No	The ID of the resource group.	rg-acfmxazb4ph6aiy****
Tag	array<object>	No	The tags of the resource.
	object	No
Key	string	No	The key of tag N to add to the resource. You can specify up to 20 tag keys. The tag key cannot be an empty string. The tag key can be up to 128 characters in length. It cannot start with `aliyun` or `acs:`, and cannot contain `http://` or `https://`.	FinanceDept
Value	string	No	The value of tag N to add to the resource. You can specify at most 20 tag values. The tag value can be an empty string. The tag value can be up to 128 characters in length and cannot contain `http://` or `https://`. The tag value cannot start with `aliyun` or `acs:`.	FinanceJoshua
