Oh, thanks. hmm, maybe we are getting there but still lost. I don't think I am generating lnurls, my deeplinks  look like this: "lightning: lnbc..."

So I guess I need to learn 2 steps:

1) How to create LNurls (instead of bolt11)
2) Encode the LNurl with params into a deeplink

is that right?

Easiest way to create a LNurl invoice with params?

Ok I think I understand more. It sounds like you are already generating [lnurls that deeplink to lightning wallets from the browser](https://blog.simple-bitcoin.app/deeplinks-lightning-how-it-works-and-why-its-important-for-bitcoin-ux/). In that case, yes, all you need to do is send the 'successAction' object in the response given from the callback url. To display a url, the successAction object needs to look like:
```
{
   "tag": "url",
   "description": "Thank you for your purchase. Here is your order details", // Up to 144 characters
   "url": "https://www.ln-service.com/order/<orderId>" // url domain must be the same as `callback` domain at step 3
}
```
