How to implement a maintenance mode for Heroku API -

i want utilize maintenance mode on heroku.

but api, maintenance mode not seem work. api calls stopped in tracks because there no header 'access-control-allow-origin' present. there no way know if api in maintenance modeā€”or if it's not responding.

is there way utilize heroku maintenance mode when app api?

currently, unfortunately not. when set custom maintenance page gets embedded iframe within heroku-served html page. you've identified, cors headers not set api client won't fetch page.

see is there way have heroku error/maintenance url served straight without iframe

api heroku maintenance maintenance-mode
