I want to know how does a web checkout 'scan' a transaction once the payment wallet is generated, if anyone can share some code regarding this auto-trade of bitcoins.

I would like to know how does ti work on a checkout app on PHP, JS or Python.

Your question is unclear. Are you asking how the merchant knows that he has been paid? If so, it does it the exact same way that every wallet does. It connects to a node (or is a node) and is notified when the node learns of a transaction which spends to the addresses it is watching for.

If I understood you right. You can use getrawmempool in Bitcoin core.
It also has api with json response, so should be easily implemented with python or any other language.

I get the way to do this with a local bitcoin node, using the wallet as a daemon, I dont really know if there is a blockchain-less (or SPV) development library that can just connec tto a remote blockchain and perform the scanning and such.
