A custom SSL certificate provides you with complete control, enabling you to choose the issuing organization, track its expiration date, and extend its validity period if desired.
Note: SSL certificate upload requires Team or Enterprise plan.
Before generating custom SSL certificate, please make sure that the following steps are completed:
Your domain ownership is verified (via email or DNS record).
The Certificate Signing Request (CSR) is generated (it can be done here - please save the Private Key on your device).
The Certificate or your short domain is generated.
The steps mentioned above should result in the creation of two files:
The SSL certificate, available in .crt or .pem format, resembles the following:
-----BEGIN CERTIFICATE-----
