ACME support for SSL certificates

As of March 11 2026 the lifetime of SSL will be halfed/reduced to 200 days, and lifetime will be further reduced to 90 days until 2029. This will require SSL automation for SSL resellers which usually involves ACME protocol and certbot (see https://certbot.eff.org/ ).

As of today, several SSL vendors are already offering SSL automation (including orders) via ACME certbot.

This process involves registering via certbot with the SSL vendor, for example:

certbot.exe register --server https://acme.sslreseller.pl/directory/ --eab-kid z2r7_XC57nZxHvCbyjRk94y866hq12CWPLdU7naHaXXXXXXXXXXXXXXXXXX --eab-hmac-key YjExMjNiNzQ1bgI0NjO0nWU3ZjmWNdZjMzhoOGRiYjhJNjFlMjBjOGXXXXXXXXXXXXXXX

After registration, SSLs may be ordered via certbot/ACME, example:

certbot.exe certonly --manual --key-type rsa --server https://acme.sslreseller.pl/directory/ --preferred-challenges dns-01

How is WHMCS planning to support ACME/certbot integration for SSL resellers?

With SSL certificate lifetimes shrinking to 200 days and eventually 90 days, automation is becoming less of an option and more of a requirement, pushing resellers toward ACME-based workflows using tools like Certbot for seamless renewals and DNS-01 validation. In the WHMCS ecosystem, there isn’t a single universal “built-in” ACME standard rollout announced for all vendors, but instead the platform typically leans on provisioning modules, hooks, and third-party integrations that already connect Certbot/ACME-style automation into hosting and SSL workflows. It’s a bit like how a platform such as fullmatch-replay.org preserves complete football experiences instead of fragments—automation ensures nothing expires or breaks mid-cycle, keeping everything continuously available without manual intervention.

The updates supporting ACME truly deliver engaging experiences. Explore and research them to apply them effectively. Every shared experience https://musicgames.io/sprunki-game is truly valuable.

At the moment, WHMCS does not provide native, universal ACME client functionality for reseller SSL modules (like running certbot flows directly inside WHMCS for external ACME CAs).

That’s an important question! Integrating ACME and certbot automation into WHMCS would greatly simplify SSL management for resellers. https://growagardenio.io
