how generate qr-code for request payment

[rasdotsu]

Hello,

I found some specs, but still not undertood.

What spec can be used to generate payment request qr-code ? I read about bitcoin:... and x-btc:... but what spec works now and can be used ?

Thanks.

There are many libraries to generate QR-codes. You just need to encode the payment address and amount.  Are you having a hard time generating the addresses instead?

liberaries I have, yes, many libs exists. I not understood what spec for uri and etc must be used to encode with QR/

So I must build proper string/uri for actions.

I think this describes it:  https://github.com/bitcoin/bips/blob/master/bip-0021.mediawiki
