 ## Protocol flow
 
-1. Client calculates a recipient's lnurl pay request url from the `zap` tag on the event being zapped (see Appendix G), or by decoding their lud06 or lud16 field on their profile according to the [lnurl specifications](https://github.com/lnurl/luds). The client MUST send a GET request to this url and parse the response. If `allowsNostr` exists and it is `true`, and if `nostrPubkey` exists and is a valid BIP 340 public key in hex, the client should associate this information with the user, along with the response's `callback`, `minSendable`, and `maxSendable` values.

 2. Clients may choose to display a lightning zap button on each post or on a user's profile. If the user's lnurl pay request endpoint supports nostr, the client SHOULD use this NIP to request a `zap receipt` rather than a normal lnurl invoice.
 3. When a user (the "sender") indicates they want to send a zap to another user (the "recipient"), the client should create a `zap request` event as described in Appendix A of this NIP and sign it.
 4. Instead of publishing the `zap request`, the `9734` event should instead be sent to the `callback` url received from the lnurl pay endpoint for the recipient using a GET request. See Appendix B for details and an example.
