wdym? the flow is: user submits the form, we auto invoice their paypal. then we set a 2 min timer for the user to pay the invoice. if user pays, paypal sends us a webhook. we then update a db field. frontend continually checks updated field value in mongodb every 5 sec. if the user does not pay, (2 min goes past), and no paypal webhook sent, then we cancel the invoice and update state to show an error on frontend

instant updates from route handler to frontend

ye well it would depend on how fast the user pays the invoice. so ill probs set a max of 2 min, and then stop checking and cancel the transaction

So rn, when the user submits the form we auto invoice them based on the details they put. Then when the invoice is paid PayPal sends a webhook. There I would update that transaction in my db, and on the frontend I constantly check with a timer for any changes of that value right

so rn when a paypal invocie is paid, i get the event, verify it, update in mongodb, and then i need to let the poll know:

if (updateStatus) {
      // todo: add long polling notify here
      return NextResponse.json({ status: "success" });
    } else {
      return NextResponse.json({ error: "Failed to update transaction status" }, { status: 500 });
    }

if (updateStatus) {
      // todo: add long polling notify here
      return NextResponse.json({ status: "success" });
    } else {
      return NextResponse.json({ error: "Failed to update transaction status" }, { status: 500 });
    }
