You do not need to give a domain when buying. After payment:
- Go to your client area → My services → your certificate.
- Paste the CSR generated on your server. In cPanel it is under SSL/TLS → Generate CSR.
- Choose how to validate the domain: email, HTTP file or DNS record.
- Complete the validation and the certificate is issued automatically.
Once issued you can download and install it, or ask us to install it for you.
