I haven't been on the PayPal Developer Docs for a while, and it seems they changed a lot. Can you please point me to the Docs where they explain the payment flow where you do not have a PayPal button, but use your own checkout flow / button? This likely should direct or open PayPal in a new window and redirect to my page after successfull transaction. All I can find are these Smart Buttons?! I am a bit lost... Thanks in advance.
