Hello

I used to create invoices through external api in version 12

In order to calculate taxes I was calling 

compute_taxes on  account.invoice

I know that now in version 14 it is invoice is replaced with 

account.move

but the method to re-calculate taxes does not exist anymore 
There is  _recompute_tax_lines but it seems to be private so cannot call it remotely. 

How can I force to recalculate the invoice lines in version 14 ? 

Thanks for your help
