I am using a controller to listen for jsonrpc calls to my odoo server. The call with the right parameters creates a sale.order, accordingly sale.order.line objects, confirms the sale.order and calls so._create_invoices() to get an account.move object. 

Now I want this account.move to be paid. How can I achieve this? I unfortunately do not quite understand how the models account.move, account.move.line, account.payment, account.partial.reconcile and others are connected to each other in a way, that I can manipulate them?
