OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

The operation that you want to perform. Set the value to AttachSecurityGroupToVpcEndpoint.

EndpointId String Yes ep-hp33b2e43fays7s8****

The ID of the endpoint that you want to associate with the security group.

DryRun Boolean No false

Specifies whether to only check the API request. Valid values:

true: only checks the API request. If you select this option, the endpoint is not associated with the security group after the request passes the check. Check items include whether the AccessKey pair is valid, whether the RAM user is authorized, and whether the required parameters are specified. If the request fails to meet the requirements in the check items, an error message is returned. If the request meets the requirements in the check items, the DryRunOperation error code is returned.

false (default): checks the API request. After the request passes the check, the 2XX HTTP status code is returned, and the endpoint is associated with the security group.
