Good morning Cezary,
Currently, c-lightning can PAY amountless invoices via the "pay" command, but
cannot CREATE them via the c-lightning "invoice" command.
To pay an amountless invoice lntb... 4 satoshis in c-lightning: lightning-cli
pay lntb.. 4000
However the internals of c-lightning should be able to handle creating
amountless invoices (it is only the JSON-RPC command itself which requires the
amount, but the rest of the code treats it as optional). I will see what I can
do to make creating amountless invoices in c-lightning possible.
Regards,
