Is there any specified way to catch Solana pay transactions?

Question

How can I get Solana pay transactions from Solana mainnet cluster?

Answer 1

You can check for the reference, which is the publickey of a keypair generated and added to a Solana Pay transaction

import {findReference} from "@solana/pay"

// Check if there is any transaction for the reference
const signatureInfo = await findReference(connection, reference, {
     finality: "confirmed",
})
