before_init_transfer
@extendable function before_init_transfer(sender: account, recipient_id: byte_array, asset: asset, amount: big_integer, hops: list<byte_array>, deadline: integer)(source)
Extendable function that allows the developer to add more functionality to the init_transfer function, before the transfer is initialised.
This allows, for example, to check that any condition is met before the transfer is initialised.
If this function throws, the transfer will not be initialized.
Throws when any extension of this function throws.

the ID of the recipient account on the end chain
