The structure that contains the template body. The template body must be 1 to 524,288 bytes in length.

If the length of the template body exceeds the upper limit, we recommend that you add parameters to the HTTP POST request body to prevent request failures caused by excessively long URLs.

You can specify one of TemplateBody and TemplateURL, but you cannot specify both of them.

--StackPolicyURL

The URL of the file that contains the stack policy. The URL must point to a policy that is located on an HTTP or HTTPS web server or in an Object Storage Service (OSS) bucket, such as oss://ros/stack-policy/demo or oss://ros/stack-policy/demo?RegionId=cn-hangzhou.

The callback URL for receiving stack event N. Only HTTP POST is supported.

• Maximum value of N: 5.

• Each URL can be up to 1,024 bytes in length.

When the status of a stack changes, ROS sends a notification to the specified URL. When rollback is enabled for the stack, notifications are sent if the stack is in the CREATE_ROLLBACK or ROLLBACK state, but are not sent if the stack is in the CREATE_FAILED, UPDATE_FAILED, or IN_PROGRESS state.

ROS sends notifications regardless of whether you configure the Outputs section. The following sample code provides an example on the content of a notification:

{
    "Outputs": [
        {
            "Description": "No description given",
            "OutputKey": "InstanceId",
