[Lightning-dev] lookupinvoice

[Sarat G]

Hi Rusty,

Thanks for your reply.

I'm using the C lightning repo for my project(
https://github.com/ElementsProject/lightning). Sorry, I framed the question
wrongly. Yes, I can use listinvoices to look up for the invoices created at
the node.

My scenario is something like this, I'm looking up whether an invoice gets
paid or not at the receiver end. For that at this point, I'm calling
waitinvoice to see whether an invoice gets paid or not. I would like to
know is there any way that the receiver could be aware that the particular
invoice created by it paid or not.

The problem is using waitinvoice in my case, it's making my process hang
till the invoice gets paid. Some workaround which I'm using for this
problem is I'm looking up the difference in amount of the label
"msatoshi_to_us" while running the listpeers command.

Thank You.

Regards,
Sarat G
