Replaces a tag in a Google Tag Manager workspace with a full Tag resource payload
Replaces a tag in a Google Tag Manager workspace with a full Tag resource payload. Workflow: gtm_get_tag, edit the payload, gtm_update_tag, then version and publish.
Full replacement Tag resource (object or JSON string) matching the Google Tag Manager API v2 Tag spec; the update replaces the tag entirely, so include every field the tag should keep. Workflow: gtm_get_tag -> edit the payload -> gtm_update_tag. Read-only fields are stripped automatically.
