Deleting a Resource Tag

Function

This API is used to remove specific tags from resources (such as models, datasets, and services). For example, in resource management or classification, you can delete tags to adjust or clear resource metadata. By calling this API, you can delete specified tags in batches. You must have sufficient permissions and the target resource must exist. After the tags are deleted successfully, the resources do not contain the specified tags. If the deletion fails, an error message is returned. Common exceptions include permission verification errors, resource non-existence errors, and parameter verification errors.

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.
