Robosats remains unaffected.

I guess so? I still don't really get why Bob/Carol can't just pay Alice through invoice generated through Alice's LNC connection into some database on magicwebstore's backend, BUT...You would have to look at the alby dev docs. It seems backwards than how it is commonly used, which as a payer tool, not a payee tool, but it could be both maybe. As you know Lnbits is kind of the go-to for webhook stuff though. I personally would use BTCPay on Alice's end but regardless I like the project and I like the vision and hope you find the solution you need!

Seems like Alby would be the best way to go about it then. LNC requires a client/server relationship. Alby is a pretty nice go between for services and nodes(via LNC) though.

I can't imagine a scenario where I would want to do that. Why can't Bob/Carol just pay Alice by triggering an invoice through Alice's store? There is no scenario where Bob or Carol would need to connect to Alice's store.

Just tested with alby and terminal web. I generated multiple invoices in quick succession using the same LNC pairing phrase with expires of 1 day.

Okay got it. Makes more sense now. I just tested it myself and I generated an invoice that expires in 5 minutes on my Zeus connected via LNC. Closed the app, then opened again and generated a different invoice with an expiry of 4 minutes with no issue.

Super, can you specify exactly what is happening? I tried to reproduce your issue but couldn't.

I have one node, and generated 3 LNC pairing phrases. I put one pairing phrase in Zeus on my android phone. I put a different one in Zeus on my graphene phone. And I put a different one in terminal web.

I generated an invoice on each service, 3000,4000,5000 and it all generated fine.
