DNA SSL - Domain Name API SSL Certificates Module for WHMCS

Sell SSL Certificates in WHMCS with Domain Name API

DNA SSL is the free, official WHMCS module for selling the SSL certificates of your Domain Name API reseller account: Sectigo, Comodo, GeoTrust, RapidSSL, Thawte, GlobalSign, AlphaSSL and PrimeSSL. Orders open automatically when the service is activated, clients configure and validate their certificate from the client area, and the issued certificate is delivered right there.

No Server Setup

There is no server record to create. Enter your Reseller ID and API Key on the product, tick Test Mode to try everything against the Domain Name API test environment, and pick the certificate from a list loaded live from your catalogue with your reseller cost.

Features

Automatic ordering on activation, renewal as a new order that reuses the client's CSR
CSR paste or generation: clients without a CSR get one generated, with a private key download
Domain validation by e-mail, HTTP file or DNS (CNAME), with the exact file or DNS record to publish
Additional domains (SAN) up to the package limit on multi-domain certificates
Certificate download (certificate + CA bundle) and reissue from the client area
Admin tools: Refresh Status and Revoke Certificate buttons, optional revoke on termination
Safe by design: the CSR's domain is checked before submission, approver e-mails are limited to the domain's own mailboxes, API key and private keys are never written to logs
Multilingual: English and Turkish client area and admin labels, following the client's and the admin's language

Quick Installation

Download the module with the Download button on this page, unzip it and upload the modules folder to your WHMCS root directory (the module lands in modules/servers/dnassl)
Create a product (type Other) and choose DNA SSL Certificates on the Module Settings tab
Enter your Reseller ID and API Key (tick Test Mode for a test key) and save
Pick the certificate from the list and save again

No manual database setup (the module creates its own table on first use), no cron job and no Composer dependencies.

Documentation

An installation guide in English and Turkish is included in the download package. A Domain Name API reseller account with SSL products is required.
