Payment gateway
A payment gateway is the piece that carries payment information between your buyer and the payment provider you've chosen.
When someone clicks buy on your site the gateway takes their payment details, hands them safely to your provider, waits for the yes or no, and passes that answer back to your site so the sale can finish. It doesn't hold the money and it doesn't take custody of anything. Think of it as the messenger that stands between buyer, seller, and provider and keeps the whole handoff secure.
How a payment gateway works
The gateway sits between your website and the providers you connect. Your buyer clicks a buy button. The gateway routes their payment details to whichever provider is handling that sale. The provider does the real work of moving the money and then tells the gateway it went through. The gateway passes that confirmation back to your site so you can send a receipt or unlock what they bought. All of that happens in the couple of seconds between the click and the thank-you page.
Why sites use a gateway
Providers announce a finished payment by firing off a little message called a webhook. To catch those messages yourself you'd need something running around the clock to listen for them, retry the ones that don't arrive, and keep a record of every sale so you can match a payment to the right order. For a simple site that's a surprising amount of machinery for one feature. A gateway carries that weight for you. The provider's webhook arrives at the gateway instead of at you. The gateway logs it and checks that it's real. Your site simply hears that they paid. Your page stays simple and you get to think about your product instead of plumbing.
One buy button for the ways you accept
Most gateways speak to a single provider. Coin Moebius is built for the shop that wants to accept payment more than one way. You connect the providers you already use and Coin Moebius pulls them into one buy button. You get one place to watch every sale that button makes, no matter how the buyer chose to pay. Your buyer never has to hunt through options and you never have to check a different screen for each one.
And the money is never the gateway's to hold. Every payment settles straight into an account you own with your own provider. Coin Moebius just routes it, records it, and confirms it, and charges one flat fee for the service instead of a cut of the sale. You can read how the buy button works or see what it costs whenever you're ready.
Get paid without the plumbing
Coin Moebius is the part behind the button, so you do not have to build it.
