Manual certificate uploads for Eco dynos with Heroku SSL

Change effective on 08 February 2024

You can now manually upload certificates for apps using Eco dynos. While Automated Certificate Management is available for all dynos, you now also have the option to use a wildcard certificate or a different certificate authority for your application instead. Run this command to manually upload your certificate:

$ heroku certs:add server.crt server.key
