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.
