Question

Is it possible to have many SSL certificates in the single Heroku Application ?

Answer 1

Recently heroku has added automatic LetsEncrypt TLS certificates for paid dynos, hobby and up. This will work across any number of domains and subdomains automatically. This method only works if you don't need wildcard subdomains.

Additionally you can manage the LE certification yourself across multiple domains and subdomains, with certbot

certbot certonly --standalone -d example.com -d www.example.com -d test.net

You can refer to this heroku doc for uploading custom certificates.
