Hello,
Thank you for your question about providing HTTPS for your customer in your Reseller account. In order to do that you have to provide an SSL certificate. Depending on the level of security you can either provide a free SSL certificate, or you may need to purchase a certificate (or have your customer buy it. Follow this guide for more info: How to Purchase an SSL Certificate from the InMotion Store. You may also want to review the tutorials within the Everything Reseller guide for more information.
If you have any further questions or comments, please let us know.
Regards,
Arnel C.
