Questions about the vhsys API
Is the vhsys API free?
API access depends on the plan you contracted. Confirm with vhsys whether it is included.
Do I need to write code to use the vhsys API with iTeam?
Not necessarily. The iTeam deployment team sets up the integration from vhsys's documentation.
Does the agent issue invoices on its own?
It can prepare them and, with permission, issue them. We recommend leaving issuing under human approval.
