In NostrGram it's in your profile edit, but if that's not updating for you most clients will take either the Lud06 (normal LNURL...) or Lud16.

Found it. so my Lud16 looks like ........ @getalb.com ?
I zapped you 50 SATS, can you zap back?
Zap'd and got confirmation.
Thanks for your help on this. How did you receive confirmation, through nostrgram, alby or wallet?
NostrGram checks the return response to see if it's been verified. Yours showed as verified. It also got verified via Alby.
