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,
