Tag Manager API create trigger 500 error

We have encountered an issue with one of the Google Tag Manager API methods, which suddenly appears to be experiencing a 500 “Experienced an internal error” outage. Since there is no real public GTM API support team like Google Analytics, we appreciate it if you could direct us to the appropriate support channel to address this matter.

El informe identifica el endpoint Google Tag Manager Create Triggers y proporciona una solicitud POST de ejemplo, pero no menciona ningún archivo del repositorio ni ninguna prueba. Empieza reproduciendo la solicitud y determina si el fallo está en esta biblioteca cliente o en la API externa; para darlo por terminado, se requiere un cambio accionable en el repositorio o la confirmación de que el problema corresponde al proveedor de la API.
