Connect your own gateway

Stripe, PayPal, Square, Shopify, Paddle, Mollie, SumUp, Authorize.Net, NMI, Razorpay, Paystack, crypto processors, Skinloop, Cash App, PayPal Friends & Family and gift cards: what you need, where to find it, and how ShopFast confirms every payment.

Your own gateway is the other way to get paid next to ShopFast Pay. You connect it with your own account’s credentials: there is no review and nothing for ShopFast to set up first. Buyers pay your account and ShopFast takes no fee on those orders (payment models).

Open Money → Payments (or the Choose how you get paid step in Get started) and pick a gateway. The panel walks you through it step by step, with a drawing of each screen you need in the provider’s dashboard, the exact values to copy, and a link to the right page. Get paid: the complete guide shows every step with screenshots, and gateway by gateway what differs per gateway.

Who takes your payments after you connect

• ShopFast Pay is not available for your store (you have not applied, or are not approved yet): connecting a gateway that can take payments moves your store to your own gateways right away. The panel says Buyers now pay through your own gateways. A gateway with one step left (Shopify’s approval, Stripe or PayPal onboarding) moves it when that step is done.
• Your store is already on your own gateways: buyers can pay with the new gateway at once.
• ShopFast Pay takes your payments: the gateway is added and ready, and buyers keep paying through ShopFast Pay until you pick Your own gateways at the top of Money → Payments.

You can change who takes payments at any time with that choice, as payment models explains.

How every payment is checked

An order is created, and its keys or files delivered, only when all of these hold:

• the payment comes from the provider itself: ShopFast checks the provider’s signature where it signs, and always reads the payment back from the provider with your credentials before trusting it;
• it is for the checkout ShopFast created (its id or order code), at the provider the buyer chose;
• it is complete (not pending, partly paid or held);
• the amount and currency are exactly the checkout’s total: a payment that is a cent short, or the same number in another currency, does not count;
• it has not been counted before: a notification sent twice, or a second payment for the same cart, never makes a second order. A second payment for another checkout of the same cart is refunded where the provider allows it; a second payment for the very same checkout (a pay link used twice) sends you a notice with the payment to refund.

Some providers’ pay links stay usable after ShopFast closes a checkout (a PayPal link, a Shopify draft order). If a buyer pays a checkout you cancelled, or one you cancelled in Fraud Shield, the order is made but held: nothing is delivered until you release it or refund it. A checkout that only ran out of time still delivers when its exact total arrives late (a pending PayPal payment, slow crypto confirmations).

Prices always come from your store, never from the buyer’s browser. Chargebacks your gateway reports (Stripe, PayPal) mark the order as disputed, and a Skinloop trade the buyer reverses after delivery counts as a lost chargeback: the order’s keys and licenses end.

Where buyers pay

With most gateways, buyers never leave your store to pay. Pay opens a window over your checkout with the gateway’s own form: Stripe’s checkout, PayPal’s buttons, Square’s card fields, Razorpay’s or Paystack’s payment window, Paddle’s checkout, SumUp’s card form, Authorize.Net’s form or NMI’s card fields. The window is ShopFast’s pay page, served on your store’s own address. Card and account details go into the gateway’s own fields; ShopFast never sees them. Wallets like PayPal open their own popup, and a bank that asks for 3-D Secure shows its check in place.

If the gateway’s form cannot load in the window (a blocked script, or the gateway refuses to open there), the window says so and offers the gateway’s own page for the same payment, so a buyer is never stuck. Closing the window brings the checkout back. Whatever the window shows, the checks in How every payment is checked are the same: the window only tells ShopFast to look, and ShopFast asks the gateway itself.

Every way to pay at checkout

Your checkout lists each way to pay your gateway offers as its own choice, with its mark: with Stripe, every method you turned on in Stripe (Settings → Payments → Payment methods), such as Amazon Pay, WeChat Pay, Alipay, Cash App Pay, Klarna, Afterpay, Affirm, Revolut Pay, PayPal, iDEAL, Bancontact or SEPA Direct Debit; with PayPal, PayPal, Pay Later, Venmo and cards; with Square, cards and Cash App Pay. Apple Pay, Google Pay and Link show inside Card: the buyer’s device offers them there. Card opens Stripe with every method you have on, so a method ShopFast does not list yet still works there. Any other choice opens the gateway on that method alone; if Stripe refuses it for the order (not activated, outside its amounts), the buyer stays on your checkout with “not available for this order right now” and picks another way to pay. Orders record how the buyer actually paid. Cash App Pay and direct debits (SEPA, ACH, Bacs) count as cards for your order limits, because buyers can reverse them.

• What shows where. A method shows only in currencies it can charge in (iDEAL in euro stores, Cash App Pay in dollar stores) and only to buyers from countries the gateway offers it in (iDEAL in the Netherlands, Bancontact in Belgium). Money → Payments lists the rest under “Not offered in” your currency.
• Stripe’s list stays current. ShopFast reads your methods from Stripe when you connect, once a day after that, and when you click Refresh on Stripe’s row in Money → Payments. A restricted key needs Read access to Payment Method Configurations for this; without it the row says so, and checkout keeps the last list (cards, Apple Pay and Google Pay to start). With Read access to PaymentIntents too, each order shows exactly how the buyer paid. With a payment method configuration ID (under “More Stripe settings”), its methods are used instead of your account’s defaults.
• The publishable key. Stripe’s row says when buyers still leave your store for Stripe’s page. Paste the publishable key (pk_live_…) there and click Save: ShopFast checks that it is a publishable key of the same mode as your secret key, that Stripe knows it and, where Stripe’s keys show it, that it belongs to the same account.

What happens to your credentials

• ShopFast checks them with the provider before saving anything. Keys the provider refuses, test keys while checkout takes real payments, or a key of the wrong shape are turned down with a message under the field.
• Saved credentials are encrypted and never shown again, not to you and not to your team. To change them, connect again; Disconnect removes them (and the webhook ShopFast added, where it added one).

Cards and wallets

Crypto

Crypto payments cannot be pulled back by ShopFast: refund them from the processor or your wallet.

Skins

Skinloop lets buyers pay with CS2 and Rust skins from their Steam inventory. You paste a Skinloop API key, add your store’s address as a redirect origin and ShopFast’s webhook address in Skinloop, and paste the webhook’s signing secret. If your key allows only one game, say which in Games. Skinloop prices in US dollars only, so your store must sell in USD. CS2 trades can sit in Steam’s trade hold for up to eight days: those orders wait, and are delivered once Skinloop confirms the trade. A payment Skinloop reverts before it completes pays no order; one reverted after delivery is a lost chargeback on that order.

Person to person: Cash App and PayPal Friends & Family

Buyers send money to your $Cashtag or PayPal account with a short order code (like SF-7KQ2M) in the note. ShopFast shows them the exact amount, where to send it and the code, and confirms the payment by itself:

• PayPal Friends & Family: your Gmail forwards PayPal’s “You’ve got money” emails (from [email protected], with “Transaction ID” in them) to your ShopFast address for PayPal, which works with any PayPal account. ShopFast accepts an email only if PayPal’s own signature checks out, it was sent to your PayPal email, and it carries the code and the exact amount. On a Business account you can also paste ShopFast’s address in PayPal’s Instant Payment Notification settings; each notification is checked with PayPal. A payment reported both ways counts once.
• Cash App: your Gmail forwards Cash App’s receipt emails (from [email protected]) to your ShopFast address. ShopFast accepts a receipt only if Cash App’s own email signature checks out, it was sent to your email, and it carries the code and the exact amount.

After you connect either one, the panel shows your ShopFast address, then Gmail’s forwarding confirmation code the moment it arrives (so you never open that email), and finally when the last payment email came in.

A payment with the wrong amount or without the code is not confirmed: you see it in Money → Payments and sort it out with the buyer.

These are personal payments. PayPal’s terms do not allow Friends & Family payments for goods, and Cash App can limit personal accounts that take business payments; buyers get no purchase protection. A Cash App for Business account, or PayPal checkout (with keys or just your email), avoids that.

Gift cards: Binance, Steam and cards you add

Buyers pay with another company’s gift card: they buy one on Eneba or G2A and send you its code. You redeem the code, then confirm the order, and only then is anything delivered. Install Gift cards in Money → Payments → Your own gateways (there is nothing to connect), then pick the cards you take:

• Binance is ready to use: USDT cards for orders in US dollars, in the usual values.
• Steam takes the values and currencies you sell for (a US card for USD orders, a euro card for EUR orders).
• Add another card for any other gift card, with its own name, picture, values and instructions.

Each card has a picture buyers see (ShopFast’s drawing, or your own from the media library) and the Eneba and G2A pages where buyers buy it. Paste a page for the card, or a page for each value when the site lists them separately; buyers then get Buy on Eneba and Buy on G2A buttons for exactly the value they need, opening in a new tab. Links must be https pages on www.eneba.com or www.g2a.com themselves: links to other sites, look-alike addresses and links that send buyers somewhere else are refused when you save.

At checkout the buyer picks Gift card, then a card, and sees exactly what to buy: the value that covers the order (a $23.50 order is one $25 card; a large order can take up to five cards). Because cards come in fixed values, you choose what happens to the difference: it becomes the buyer’s store credit when you accept, or you keep it. The buyer reads which before buying.

When a buyer sends a code, the order waits in Orders → Awaiting payment with To review, and you get a notification. Open it, choose Show the codes, redeem them in Binance or Steam, then Accept and deliver, or Turn down with a reason the buyer reads (they may send another code within an hour, or you close the order). Codes are encrypted, only people who can confirm payments see them, every viewing is in your activity log, and a code can be sent to ShopFast only once, at any store.

Currencies

Each gateway takes payments only in the currencies it supports. When a gateway cannot take your store’s currency (Paystack takes only USD of ShopFast’s currencies, PayPal does not take NPR, a Square location or a Shopify store takes its own currency), the panel says so before you connect it and checkout does not offer it.

Test it

After connecting, place a small order on your store with that way to pay. It is marked paid (and delivered) as soon as the gateway confirms it. Where the gateway has a test mode, ShopFast’s test mode for your store runs checkouts without real money.
