v0 payments, card checkout for Next.js apps built in v0
v0 produces clean Next.js and React interfaces fast. eCom Pay fits the way v0 works, a card form component that drops into the checkout you generated, with the bank check inside it and order confirmation driven by signed payment updates on the server.

Frequently asked
Can a v0 app take card payments in the UK?
Yes. Create a free test account at the eCom Pay dashboard, paste the eCom Pay prompt into v0, and it adds a browser encrypted card form with Apple Pay, Google Pay and 3D Secure. Test with test cards, then swap one key to go live once approved.
Does eCom Pay work with Next.js and Vercel?
Yes. The card form runs in the browser and the signed payment updates arrive at a normal route handler, so a v0 app on Vercel needs nothing special.
Who approves the account?
A UK team reviews every new account, usually within one working day, and approval lands in 24 hours once your documents are in. There is no automated decision.
Generated the whole storefront in v0 and stalled at the payment step?
The interface is the easy part. Taking money needs an approved account, encryption of card details before they leave the browser, and a server that only confirms orders when the payment is real. The eCom Pay prompt tells v0 how to do all three.
How v0 builds, and where the checkout goes
v0 generates Next.js apps with shadcn style components, usually deployed on Vercel. The eCom Pay card form becomes one component on the checkout page, a route handler receives the signed payment update, and refunds are issued from your dashboard.
How to add card payments to your v0 app in three steps
Create a test account
Sign up at the eCom Pay dashboard and you are in test mode straight away, with test cards. Nothing goes live until our team has approved your account, usually within one working day.
Paste the prompt into v0
Copy the eCom Pay prompt from the docs into your builder. It tells the AI how to add the card form, confirm payments and handle refunds. Test with the test cards until the flow is right.
Swap one key to go live
Once approved, we add your live account details to your dashboard. You swap your test key for the live one. Nothing else in your app changes.
The prompt to paste into v0
This is the short version. The full prompt for AI coding assistants, with the test card numbers and the signed update format, is on the docs page.
Add eCom Pay card payments to this app. Follow the integration guide at https://docs.ecompay.co.uk/ exactly. Use my test mode key until I say go live, show the embedded card form on the checkout page, confirm the order only when the signed payment update arrives, and never store card numbers.
What your checkout gets
Built and tested on the eCom Pay gateway. The same checkout whichever tool built your app.
Card details encrypted in the browser
Card numbers are encrypted on the customer's device before they leave the page. Your app and your server never see them, which keeps your build simple and your customers safe.
Embedded form or hosted page
Drop the card form into your own page, or send customers to a ready made eCom Pay checkout page when you would rather not build one.
Apple Pay and Google Pay on one switch
Turn wallets on in your dashboard. No Apple or Google developer setup on your side.
3D Secure handled for you
The bank check, including the frictionless flow, runs inside the form. Nothing extra to build.
Payment links and QR codes
One off or reusable links from the dashboard, with a QR code, WhatsApp sharing and up to three reminder emails until it is paid.
Signed order updates
Every payment, refund and dispute update is signed, so your app can prove it came from eCom Pay before it changes an order.
Refunds only when you choose
Full or partial, from the dashboard or from your own system. Nothing is refunded automatically.
Next working day settlement
Money lands the next working day with no rolling reserve, the standard eCom Pay proposes to every merchant, subject to approval.
Businesses eCom Pay approves on AI built apps
Everyday online businesses, and the specialist sectors that need a specialist. Every account is reviewed by a UK team, not an automated model.
v0 payments, frequently asked
Is there a React component for the card form?
The docs show how the embedded form is added to a React or Next.js page, and the prompt handles it for you in v0. Node and Python libraries cover the server side.
Can customers pay with Apple Pay on a v0 site?
Yes. Apple Pay and Google Pay are one switch in your dashboard, with no Apple or Google setup on your side.
What does a customer see when a card is declined?
A clear message in the form, and the chance to try another card. Your order is only confirmed when the signed payment update says the bank approved it.
Can eCom Pro finish the integration?
Yes. Send the project over and eCom Pro, our sister development company, finishes the checkout and tests it with you, quoted per job.
