12. In this step, you have to create your key. Click the appropriate button as shown below.

13. Select the key type. It is recommended to use the 'JSON' type. Finally, click 'Create' . Important! Once you proceed, the file with your private key will be downloaded to your computer. Remember to store this file in a secure place because it is not possible to regain the key when the file is lost.

14. Now, log in to your WHMCS and proceed to 'Setup' → 'Products/Services' → 'Servers' and press 'Add New Server'.

15. Next, enter your server 'Name' , 'Hostname' , 'IP Address' and select 'Google Cloud Virtual Machines' from the 'Module' field. Now, provide your Google Cloud project ID as 'Username' and paste the content of the previously downloaded file with your key details in the 'Access Hash' field. Finally, check the 'Test Connection' and save the changes.

16. It is time to create a server group. To do so, click on 'Create New Group' .

17. Enter a name, click on your previously created server, press 'Add' and afterward 'Save Changes' .

22. Now, go to the 'Module Settings' section, choose your previously created server group from the dropdown menu. The module should automatically save and reload the settings. If not, click on the 'Save Changes' option manually.

23. Now, let's start configuring the settings of the server that you sell. Configuration: Region - is a particular geographical location where you can host your resources. Each region consists of one or more zones. Random Domain Prefix - enter here the domain prefix for instances where a specific domain is not provided. Only valid hostname characters, including letters (a-z), numbers (0-9), and hyphens (-), are permitted. Machine Template - select a template to create a new VM based on the selected machine template. Note that only new VMs can be created based on templates, this option is not related to upgrades. OS Distribution - choose a preferred OS distribution from the dropdown menu. Disk Type - Standard persistent disks are efficient and practical for handling sequential read/write operations while SSD persistent disks are dedicated to enterprise applications and high-performance database needs that demand lower latency and more IOPS. Zone - is a location within a region. Once the 'Region' is selected, then you can define a zone. Machine Type - you can choose from many predefined machine types in each machine type family. Image - select a preferred OS image. Disk Size - provide the disk size in GB. Tags - you may fill in network tags separated by commas or spaces. User Data - choose the 'cloud-config' file or 'Bash' script which may be used to configure the virtual machine on the first boot. Custom Machine Settings: Series - Select the custom machine type from available. Number Of Cores - Define the number of cores that will be used. Memory [MB] - Define the allocated memory amount for the machine, use MBs. Client Area Features: Snapshots - enable if you want clients to access the 'Snapshots' section in the client area. Graphs - enable to assure access to the 'Graphs' section in the client area. Network: Network - choose a network. Network Tier - there are two tiers available, 'Standard' and the ' Premium' one. More about the differences between them can be found here IPv4 Address - you can enable the IPv4 Address. Note: This is required for the "Download RDP File" function in the client area. Custom Subnet - select the 'Custom Subnet' option when manually configuring VMs. Enable this setting during subnet creation. If a custom subnet is chosen, the selection will override any declaration in the 'Network' field.

24. At the end of the configuration process, you can decide whether you want to generate configurable options for the product. Configurable options can be used by your clients to select each virtual machine parameters individually during order placement. Otherwise, if configurable options are not defined, then the fixed parameters specified in the earlier configuration will be used instead. If you decide to use configurable options, press on the 'Create Configurable Options' button.

Now, select which options you want to generate and confirm by clicking 'Create' . Note that the configuration for disabled options will still be taken from the configuration of the main product. More information about how to use configurable options can be found here or in the official WHMCS documentation. Important: Remember that you may enable either Machine Type configurable option or Custom Machine Series with its sub-options.

SSH Keys

In the 'Custom Fields' tab you will find the 'SSH Public Key' field which is displayed to clients on the order form by default. Your SSH key must be an RSA key with a key size of either 2048 bits or 4096 bits. If you would like to limit the possibility of entering the key e.g. only to the 'ssh-rsa' format, you can use the regular expression in the validation field, such as: #ssh-rsa AAAA[0-9A-Za-z+/]+[=]{0,3}( [^@]+@[^@]+)?# Remember that API allows such action only once, during the initial VM creation. Note: If you disable the 'Show on Order Form' option, a client will not be able to provide SSH Key while placing an order.

Management
