Deleting a Service Deployment

Function

This API is used to delete a deployment of a service. If the service ID or deployment ID is invalid, the version number does not exist, or the user does not have the permission, "400 Bad Request" or "403 Forbidden" is returned.

Debugging

You can debug this API through automatic authentication in API Explorer or use the SDK sample code generated by API Explorer.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.

If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.
If you are using identity policy-based authorization, the following identity policy-based permissions are required.
