Webhook
An automatic message one website sends another the instant something happens, like a payment going through.
A webhook is how one website tells another that something just happened, with no one refreshing a page or clicking a button. The moment a buyer pays, the payment company sends a small automatic message to a web address you gave it. That message says, in effect, "a payment just came in, here are the details."
The catch is that something has to be sitting at that web address, awake and listening, ready to catch the message and write it down. On a normal website with a server, that something is a piece of code you write and keep running. On a static site, which has no server, there is nothing there to catch it. That gap is the real reason taking payments on a simple site is harder than it looks.
Coin Moebius is the thing that sits and listens for you. We catch every payment message, check that it is genuine, record the sale, and show it in your dashboard, so you never have to run a listener of your own.

Coin Moebius is the part behind the button, so you do not have to build it.
