PRE ADVANTAGES:
Our users will be able to anonymously receive payment and transfer to customers:
1. Payment codes (EX-CODE, license keys, etc.).
2. Programs (links to download, files).
3. Goods (with the indication of coordinates).
4. Information.
Would the payer be able to get a code/link after hi has paid?
Yes, using the "showBillData" function
What would the function return before the sender has paid? Empty response?
In that case I don't understand how the payer could check the paid amount before he transferred tokens.
To get a response from the "showBillData" function, you need to enter a password when you pay the bill. This password gives access to the product.
To check the invoice that you have issued, you use the secret word received from the seller when you call the function "showBillInfo"
By the way there is no method 'showBillData' in the abi you shared via the telegram chat.
