01 / Product walkthrough

The payment solution supports checkout flows, multiple payment methods, transaction tracking, refunds, settlements, and merchant reporting.

Explore the workspaces, everyday actions, and reporting behind this solution. Each module below explains what your team can manage and how the work connects.

02 / Features & functionality

Inside each module

8 modules ? Detailed walkthrough
01Module guide

Hosted checkout and SDK

Provide merchants with hosted checkout and SDK integration options for collecting payments.

  • Merchant integration. Provide a checkout entry point that connects the merchant's order to the payment request.

  • Checkout outcomes. Return a clear payment status to the merchant so the customer sees whether the purchase succeeded or requires another action.

02Module guide

Payment intents

Track each intended payment and its state throughout the transaction lifecycle.

  • Payment lifecycle. Maintain a reference for the requested payment and follow authentication, authorisation, capture, failure, or cancellation.

  • Duplicate prevention. Associate repeated requests with the same payment context so retries do not become unrelated charges.

03Module guide

Cards, wallets, and bank rails

Route supported payment methods through the appropriate provider integration.

  • Method selection. Present the payment options supported for the merchant and transaction context.

  • Provider handling. Keep method-specific provider references and outcomes connected to the same merchant payment record.

04Module guide

3DS authentication

Hand off payments for additional cardholder authentication when required.

  • Authentication handoff. Guide eligible card payments through the issuer's additional authentication step.

  • Outcome handling. Keep successful, unsuccessful, or interrupted authentication distinguishable before continuing the payment.

05Module guide

Fraud and velocity rules

Evaluate transaction patterns and velocity rules to flag potential payment risk.

  • Risk checks. Evaluate configured thresholds and transaction patterns before deciding whether a payment can proceed.

  • Operational review. Keep flagged activity and rule outcomes accessible so authorised teams can investigate unusual behaviour.

06Module guide

Refunds and chargebacks

Manage refunds and disputed transactions with a traceable operational history.

  • Refund record. Connect full or partial refunds to the original payment and retain the adjustment history.

  • Dispute handling. Track dispute status, relevant deadlines, and supporting records so the merchant can coordinate a response.

07Module guide

Merchant payouts

Track merchant payout status alongside the transactions included in settlement.

  • Payout composition. Show which settled transactions and adjustments contribute to the amount payable to a merchant.

  • Payout status. Distinguish scheduled, in-progress, completed, and unsuccessful payouts for finance follow-up.

08Module guide

Signed webhooks and reconciliation

Deliver signed payment events and reconcile provider activity with internal records.

  • Payment events. Deliver verifiable status notifications and retain event references for merchant troubleshooting.

  • Reconciliation. Compare provider transactions and settlements against internal records and investigate missing or mismatched entries.

03 / From start to finish

How it all comes together.

A secure transaction rail that gives merchants one integration for payment methods, fraud controls, refunds, and settlement visibility.
