I am publishing an app to the Azure Marketplace. My offer is a VM. My use case is that i need the customer to enter some values that will be used to call a script in the VM. How can i pass custom variables to the VM during launch?
According to this you can only customize them with SKU's, so this means any post deployment configurations are to be done by the customer.
What you see to need is an Azure Application Offer. That one would contain a way to customize it.
