For resellers using WHMCS, VDS Host offers a free server module. Once the module is installed, the entire flow from order to provisioning is automated.
Adding an upstream server
Define a new server in the WHMCS admin panel. Enter the VDS Host domain in the hostname field, your API key in the username field and your secret key in the password field. The keys are masked in the interface.
Product and OS mapping
In the module config, map the product you will sell with upstream_product_id and the operating-system options with os_map. This way a customer order connects directly to the right configuration.
Automatic lifecycle
Once setup is complete, creation, suspension, reactivation and termination run automatically through WHMCS. Your customers never see the upstream provider; everything is under your own brand.
