The checkout between Shopify and WhopSell on Shopify. Get paid through Whop.
Pendym replaces your Shopify checkout with one that charges cards through your own Whop account. Products, orders and customers stay in Shopify. The money goes to Whop, straight to you.
No monthly fee · 0.5% per order · live in about 15 minutes
Three connections, then you're selling
The wizard walks you through each one. Nothing about your store changes until the last step, and you can switch back to Shopify's checkout from Settings at any time.
Connect your Whop account
Click Connect with Whop and approve Pendym there. If Whop asks, paste one webhook signing secret, then verify a card with a $1 hold that is released straight away. The card processing agreement is between you and Whop.
Connect your Shopify store
Create a small app in your Shopify Dev Dashboard and paste its Client ID and Secret. It takes about 5 minutes, and we show every click. Pendym checks the permissions for you, then writes every paid order back so fulfilment, inventory and customers work exactly as before.
Turn it on in your theme
Copy one line from Pendym, paste it into your theme's theme.liquid file and click Save. Pendym tells you when it's live, and your store's checkout button opens Pendym instead of Shopify's checkout.
Shopify keeps the store. Whop takes the payment.
Pendym sits between the two and moves exactly one thing: the checkout page and the card charge behind it. Everything else stays where your team already works.
Stays in Shopify
- Your storefront, theme and product pages
- Products, variants, prices and inventory
- Discount codes, shipping rates and tax settings, quoted live at checkout
- Shopify Markets: buyers pay in their market's currency
- Orders, fulfilment and the customer list your email tools read
Moves to Pendym and Whop
- The checkout page, branded for your store, on your own domain if you want it
- Card processing through your Whop account, settled to you on Whop's schedule
- Subscriptions: Shopify selling plans become Whop renewals, billed every cycle
- Order bumps, and post-purchase offers that can charge the card the buyer just used
- Fraud rules and the funnel numbers behind every order
- Chargebacks from Whop, with the evidence packet filed back to Whop from Pendym
Built for the hand-off, not bolted on
The details that decide whether a replacement checkout converts as well as the one it replaces.
Opens the instant they click
The checkout is prepared while the buyer is still on the cart page, so the click is a plain page change with the order already priced. No spinner, no interstitial.
Shopify's own prices, live
Shipping rates for the buyer's address, tax the way your store charges it, discount codes and market currencies all come from Shopify at checkout time. Nothing is re-entered or guessed.
Orders land back in Shopify as paid
Every Whop payment creates the matching Shopify order with the payment recorded, so fulfilment, inventory and customer emails carry on untouched. Underpayments are marked partially paid and tagged for review.
Subscriptions through Whop
A selling plan in your Shopify cart becomes a recurring Whop plan. Renewals create new Shopify orders, and cancelling from the dashboard stops the plan at Whop.
Your pixels keep firing
Paste your Meta, TikTok and Google Analytics IDs once and the new checkout reports begin checkout, add payment info and purchase, so your ads keep learning from real sales.
A checkout you can edit
Layout, colours, custom blocks and one-page or two-page flow, previewed live as you type. Serve it from checkout.yourstore.com with one CNAME record.
What Shopify merchants ask before switching
The honest answers, including the ones about money.
That's the whole price list. No monthly minimum, no setup fee, no charge for the months you don't sell. Whop's own processing fees apply as they would on any Whop sale.
