01 The platform

Everything you'd otherwise wire together yourself.

See every module
01

Branded checkout

A hosted, pixel-matched checkout that takes your logo, colours and domain. Cards, wallets, SEPA and local methods render automatically by buyer country — no front-end work to maintain.

Live in one redirect
02

KYC & onboarding

Verify a business or a sole trader with a drop-in flow: document capture, identity checks, sanctions screening and a clean status webhook. Accept a merchant in minutes, not a back-and-forth week.

38 countries, day one
03

Fraud protection

A real-time risk score on every transaction, tuned with rules you write in plain language, not regex. Block, allow or challenge with 3-D Secure — and let the model learn from your own decline history.

0.04% net fraud rate
04

Dashboard & payouts

A console your finance and ops teams actually like: live volume, search down to the cent, role-based access and fast payouts to your bank on T+1 — or instant where the rail allows.

Payouts as fast as T+0
05

EU compliance built in

PSD2 SCA, VAT-aware receipts, GDPR-clean data handling and EU data residency are defaults, not a project. Mavenkopay carries the heavy compliance so your launch doesn't wait on legal.

SCA & VAT handled for you
06

A developer API

Idempotent, versioned, predictable. Seven SDKs, typed everywhere, webhooks that retry with signed payloads, and a sandbox that mirrors production to the status code. The docs are the product.

Sandbox in < 5 minutes
02 How it works

Four steps, one afternoon.

01

Grab your keys

Sign up, get test and live keys instantly. No sales call to write your first line, no waiting on an account manager to unblock the sandbox.

npm i @mavenkopay/node
02

Create a checkout

One call returns a hosted, branded checkout URL. Redirect to it, or mount the embedded element — both handle SCA, wallets and retries for you.

POST /v3/checkout
03

Listen for the event

A signed webhook tells you the payment succeeded, the customer onboarded, or the dispute opened. Verify the signature, update your database, done.

payment.succeeded
04

Flip to live

Swap the test key for the live key and ship. Same code path, same status codes — the only difference is the money is now real.

live in production
03 Deep dive · the request path

From request to settled, on one path.

A customer hits Pay. Mavenkopay authorises the card, runs the fraud score, triggers 3-D Secure only when the risk warrants it, captures the funds and writes the receipt — all inside a single round trip you can trace end to end.

Every step emits a typed event. You build against the path, not against a black box — and when something is declined, the response tells you exactly why, in a code your retry logic can branch on.

  • Idempotent by key — replay any request safely; a retry never double-charges a customer.
  • Smart 3-D Secure — challenge only the risky payments, exempt the rest under PSD2 to lift conversion.
  • Typed declines — every failure is a documented code, not a guess at what the bank meant.
  • Signed webhooks — verify in one line, delivered with retries and a replay log you can audit.

"We had a working branded checkout in an afternoon and were taking live payments the next morning. The docs answered every question before I had to open a ticket."

Mara Ostfeld
Founding Engineer, Hexbase

"Onboarding our sellers used to be a week of email. With Mavenkopay KYC it's a flow inside our own app — verified in minutes, status straight to our webhook."

Davide Renzi
CTO, Tidewave Markets

"The fraud score plus PSD2 exemptions lifted our authorisation rate by 3.4 points. We tune the rules in English and the team can read them. No black box."

Head of Payments, Northwind

06 Common questions

The things developers ask first.

Can I really go live in an afternoon?

If you already have a backend, yes. Sign-up gives you test and live keys immediately. Most teams have a branded checkout working in test within an hour, verify the webhook, and flip to live the same day. There's no mandatory sales call between you and your first real payment.

Which languages and frameworks do you support?

We ship typed SDKs for Node/TypeScript, Python, Go, Ruby, PHP, Java and .NET, plus a REST API for everything else. Front-end, you can redirect to the hosted checkout or mount the embedded element in React, Vue or plain JavaScript. The webhooks are framework-agnostic.

Do I have to handle PCI compliance and SCA myself?

No. Card data never touches your server — the hosted checkout and element are PCI-DSS Level 1, so you stay in the simplest SAQ-A scope. PSD2 Strong Customer Authentication and 3-D Secure are applied automatically, with low-risk exemptions claimed for you to protect conversion.

How do payouts and settlement work?

Captured funds settle to your Mavenkopay balance and pay out to your bank on a rolling T+1 schedule by default, or instantly on rails that support it. You can also hold a balance, schedule payouts, and on the Platform plan split a payment across multiple connected accounts.

What makes Mavenkopay different from Stripe or Adyen?

We optimise for one thing: how fast a developer gets to production. Same building blocks — checkout, onboarding, fraud, payouts — but obsessively documented, sandbox-first, and packaged so a small team ships without a payments specialist. If your bottleneck is integration time, that's the gap we close.

Where is my data stored?

EU customer data is processed and stored in EU regions (Paris and Frankfurt primaries, Stockholm failover). Access is logged, encrypted at rest with per-tenant keys, and exportable on demand. Our SOC 2 Type II report and PCI AOC are available under NDA from the trust center.
