Adding a Tag to an Associated Resource

A resource can have a maximum of 10 tags. (A maximum of 20 tags can be added to a resource in the region that supports Landing Zone.)

This API is idempotent. If a to-be-added tag has the same key as an existing tag, the tag will be added and will overwrite the existing tag.

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

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, no identity policy-based permission required for calling this API.
