Developers
An API you can feel good about.
Predictable REST, generated snippets in your language, hosted options for the no-code crowd, and a sandbox that behaves exactly like production.
Start here
Three integrations cover ninety percent of cases.
1 · Create a charge
curl https://api.pylonplatform.ai/v1/charges \
-u sk_sandbox_9f3k2: \
-d amount=4800 \
-d currency=usd \
-d merchant_account=mid_9f3k2 \
-d payment_method=tok_visa \
-d "metadata[order_id]=10241"One endpoint settles to whichever merchant account the transaction belongs to — yours, or one of the merchants on your platform.
2 · Tokenize a card
// Hosted fields tokenize the card inside your own UI.
// PCI scope stays light; the checkout stays yours.
<div id="pylon-card"></div>
<script src="https://js.pylonplatform.ai/v1/"></script>
<script>
Pylon.hostedFields({
tokenizationKey: "pk_sandbox_9f3k2",
fields: { card: "#pylon-card" },
onSubmit: (token) => charge(token),
});
</script>Prefer no code at all? Hosted payment pages and copy-paste payment buttons take a funnel live in minutes.

}Also in the box
SDKs for hardware
iOS and Android libraries for EMV readers and tap-to-pay, plus unattended integrations.
Generated snippets
PHP, Python, Ruby, Node, C# — the docs write the request in your stack.
Idempotency
Safe retries on every write endpoint; the same request never charges twice.
Versioned API
Breaking changes get a new version and a migration window. Old code keeps working.
Test fixtures
Cards for decline, dispute, high-risk and level 3 scenarios out of the box.
Sandbox parity
The sandbox runs the same risk engine and routing as production — surprises happen in demos, not launches.
Sandbox keys are one conversation away.
Tell us what you're integrating and we'll send keys, the docs bundle and a walkthrough of the endpoints you'll actually use.
