9. Automation & Provisioning Settings

The module implements the standard WHMCS automation commands. Each maps to a Linode API operation as follows.

WHMCS Command / Trigger	Module Function	Behaviour	Linode API Call
Create	CreateAccount	Provisions a new instance from the configured plan, region and image, applying any configurable options the customer selected.	POST /linode/instances
Suspend	SuspendAccount	Shuts the instance down. It is not deleted, so it can be unsuspended.	POST /linode/instances/{id}/shutdown
Unsuspend	UnsuspendAccount	Boots the instance back up.	POST /linode/instances/{id}/boot
Terminate	TerminateAccount	Permanently deletes the instance and clears the stored LinodeId.	DELETE /linode/instances/{id}
Change Password	ChangePassword	Shuts the instance down, resets the root password, and boots it again if it had been running.	POST /linode/instances/{id}/password
Upgrade / Downgrade	ChangePackage	Resizes the instance to the new product’s plan, with automatic disk resizing. Also applies a changed backups option.	POST /linode/instances/{id}/resize
Test Connection	TestConnection	Validates the configured access token.	GET /account/settings
Usage Update (daily cron)	UsageUpdate	Imports disk limit and monthly transfer usage for every active service on the server.	GET /linode/instances/{id} and GET /linode/instances/{id}/transfer

Important: Suspension shuts the instance down but keeps it — and Linode continues to bill your account for a stopped instance. Terminate is the only command that removes it.

Note: Linode requires an instance to be powered off before its root password can be changed. The module handles this automatically: it shuts the instance down, waits for it to reach the offline state, applies the new password, and boots it again if it had been running. If the reset fails, the instance is still booted back up rather than left powered off.
