Automated Certificate Management (ACM) for Eco dynos
Change effective on 06 August 2024
Automated certificate management(ACM) is now available for Eco dynos. Previously, customers required a Basic or higher tier of dynos to access this feature.
To enable ACM for your app, run the following CLI command:
$ heroku certs:auto:enable
Certificates handled by ACM automatically renew before they expire. It automatically creates new certificates whenever you add or remove a custom domain. See Automated certificate management for more info.
Previously, apps using Eco dynos automatically enabled ACM when a user upgraded from Eco to a larger dyno. Going forward, users must manually enable ACM for each app. Existing apps maintain their current ACM status, and the status doesn’t change when changing dyno types.
