| `client_payload` | object or string | Yes      | -       | Full replacement Client resource; the update replaces the client entirely, so include every field it should keep. Workflow: gtm\_get\_client -> edit the payload -> gtm\_update\_client. Full Client resource (object or JSON string) matching the Google Tag Manager API v2 Client spec (server containers). Must include name and type (e.g. gaaw\_client for GA4). Example: \{"name": "GA4 Client", "type": "gaaw\_client", "parameter": \[\{"type": "template", "key": "activateDefaultPaths", "value": "true"}]} |

## Output
