02:55 < Educob2> Hi. What happens if I pay (or get paid) an invoice twice? Do I pay double the amount or just once? Thanks.

04:40 < darosior> Educob2: C-lightning will prevent you to pay an invoice twice (it's insecure as you reuse the same secrets to form the routes), I think other implem will too
04:40 < Educob2> Thanks.

07:29 < Educob2> What is a better strategy to manage programmatically sending payments: 
07:30 < Educob2> 1) call synchronously pay method (await pay) 
07:30 < Educob2> 2) call pay method without waiting and use a plugin to get notified with sendpay_success event?
07:37 <@cdecker> Depends on the level of granularity you're interested in: if all you want is to get a payment from A to B you'd probably use `pay` and wait for it to complete (if desired we could add a `background=True` parameter to send it to background and then poll `paystatus`), if you require more control over individual attempts, partial payments and retries you'd use sendpay and listsendpay or
07:38 <@cdecker> waitsendpay

07:48 < Educob2> Wow! This is more complicated than I thought. Thanks.
07:50 <@cdecker> Hehe, it's more than likely you just want to use `pay` ;-)
07:51 < Educob2> But in order to use sendpay I must first call getroute. Which has weird parameters like riskfactor
07:51 < Educob2> I need granularity.
07:51 <@cdecker> Ah, ok in that case yes the primitives are there but may require some tinkering
07:52 < Educob2> Tinkering?
07:52 <@cdecker> We do expose loads of things, on a couple of different abstraction levels, maybe we should also start using man-like numbered levels to distinguish which ones should be seen by default
07:53 <@cdecker> tinkering = experimenting a bit and figure out how things fit together

08:05 < Educob2> Is it possible that the route returned by getroute doesn't work when I call sendpay?
08:05 < Educob2> If I call getroute a second time will I get a different route?
08:11 < Educob2> Is there any complete sample code for sending payments?
08:13 <@cdecker> From where are you trying to do this? Using the pyln-client library?
08:13 <@cdecker> And yes, getroute randomizes the routes in order to make an attacker's life difficult
08:17 < Educob2> No. Node. javascript
08:18 <@cdecker> I assume darosior's clightningjs?

08:19 < Educob2> Never heard about darosior.
08:20 <@cdecker> Anyhow, he might be able to point you to an existing example :-)

08:20 <@cdecker> darosior is one of our core contributors (and you spoke with him in this chat 4 hours ago ^^)

08:22 < Educob2> I am using a simple interface to c-lightning.
08:22 < Educob2> I'll take a  look at darosior. Does it have sample codes?
08:22 -!- skme9 [~skme9@2402:3a80:6ba:a174:6dea:8554:b247:3a62] has quit [Max SendQ exceeded]
08:22 <@cdecker> It has a couple from what I can tell, yes
08:22 <@cdecker> Here's the repo https://github.com/darosior/clightningjs

08:25 < Educob2> Thanks. I'll take a look
08:27 < darosior> Educob2: don't hesitate to ping me (or open issues) even with nits about clightningjs, I'm really interested in having more feedback about it (it's not as robust as pyln (yet?) )
08:28 < Educob2> Thanks. My goal is to give ln service to thousands of people so I need to find the right way to do it.
