Accelebit is a server-to-server payment gateway that gives your business a single integration point for processing card payments. You call one API and Accelebit handles provider routing, failover, 3D Secure authentication, and webhook delivery — so you can focus on building your product, not managing payment providers.

What Accelebit does

When you send a payment request to Accelebit, the gateway selects the best available upstream provider based on currency support, success rates, and current health. You never change your integration when providers change — Accelebit handles it.

Smart Routing

Transactions route to the optimal provider automatically based on currency, success rates, and health.

3D Secure

Unified 3DS handling across all providers. The API surfaces redirect URLs and challenge data in a consistent format.

Idempotency

Every mutating endpoint supports idempotency keys so you can retry safely without double-charging.

Stored Cards

Tokenize cards for returning customers and charge them by ID on subsequent payments.

How a payment works

1

Send a payment request

Your backend calls POST /v1/payments with card details, billing info, and the amount.
2

Accelebit routes the transaction

Accelebit selects the optimal upstream provider and processes the payment.
3

Handle 3D Secure if required

If the response includes threeDsRequired: true, redirect your customer to the URL in threeDsData to complete the challenge.
4

Receive the webhook

Once the payment completes, Accelebit sends a payment.captured or payment.failed event to your webhook endpoint.

Server-to-server only

Accelebit is a server-to-server API. Card details travel from your backend to our API over HTTPS. Never send card data from a browser or mobile app directly to Accelebit — you are responsible for PCI compliance on your end.
