Calagopus WHMCS Module

https://calagopus.com

Installation

1. Upload the modules/servers/calagopus/ directory to your WHMCS installation at:

   /path/to/whmcs/modules/servers/calagopus/

2. In WHMCS Admin, go to System Settings → Servers → Add New Server:

   • Module: Select "Calagopus"
   • Hostname: Your panel domain (e.g. panel.example.com)
   • Password: Your Calagopus admin API key
   • Secure: Check if using HTTPS
   • Click "Test Connection" to verify

3. Create a Server Group and assign your Calagopus server to it.

4. Create a Product and set the module to "Calagopus", then configure the product options.

Overwriting Values Through Configurable Options

Every module setting can be overwritten per service through WHMCS Configurable Options or Custom Fields, just like the official Pterodactyl module. Resolution priority:

1. Configurable Option matching the setting's friendly name (e.g. Memory (MB))
2. Configurable Option matching the setting's key (e.g. memory)
3. Custom Field matching the friendly name
4. Custom Field matching the key
5. The product's module setting
6. Module default

A configurable option named Memory (MB)|Memory works too - WHMCS only passes the part before the | to the module.

Overridable settings

For yes/no settings, override values of on, 1, yes or true enable the setting; anything else disables it.

Extra keys (no product-setting fallback)

These have no field on the product page but are honored when supplied as a configurable option or custom field:

Key	Friendly Name	Purpose
server_name	Server Name	Full server name (replaces prefix + service id)
pinned_cpus	-	Comma-separated CPU core ids, e.g. 0,1,2

Egg variables

Each egg variable can be overwritten by a configurable option or custom field named after the variable's display name or its environment variable name. Example: for a variable Minecraft Version / MC_VERSION, either Minecraft Version or MC_VERSION works as the option name.

Custom feature limits

Each key defined in the product's Custom Feature Limits field (e.g. plugins:5,worlds:3) can be overwritten individually by a configurable option or custom field with the same name (e.g. an option named plugins). The key must be present in the product's base definition to be sent to the panel.
