UnbindInstanceDomains - Alibaba Cloud DNS - Alibaba Cloud Documentation Center

Unbinds one or more domain names from a paid Alibaba Cloud DNS instance based on the instance ID.

Operation description

A paid Alibaba Cloud DNS instance whose ID starts with dns is an instance of the new version. You can call an API operation to bind multiple domain names to the instance. If the upper limit is exceeded, an error message is returned.
A paid Alibaba Cloud DNS instance whose ID does not start with dns is an instance of the old version. You can call an API operation to bind only one domain name to the instance. However, if the instance that you want to bind to the desired domain name is already bound to a domain name, you can call this operation to unbind the original domain name from the instance and then bind the desired domain name to the instance.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
