Popular questions

Direct answers for merchants and developers.

Start with integration, Sandbox, pricing, settlement, security, or account access. Contact support when your implementation needs a specific provider or market review.

Developers

Integration and webhooks

Where should I start the API integration?

Open the Member Portal to review Sandbox credentials, then follow the API Docs quickstart to create a payment intent and verify the resulting webhook.

What should my webhook handler verify?

Verify the HMAC signature, timestamp tolerance, event type, payment ID, and replay protection before changing order or payment state.

Do I need an idempotency key?

Yes. Send a unique Idempotency-Key for mutating requests so a retry cannot unintentionally create the same payment or refund twice.

Testing

Payments and Sandbox

Does Sandbox move real money?

No. Sandbox returns mock payment IDs, request IDs, events, and signatures so you can test approved, review, and declined outcomes safely.

Is every displayed payment method live?

No. Production availability depends on the selected provider, market, currency, contract, credentials, certification, and compliance approval.

Operations

Pricing and settlement

How is production pricing calculated?

A production quote is based on payment methods, markets, currencies, transaction volume, provider fees, settlement setup, FX, refunds, and dispute requirements.

Where can I review settlement activity?

Member reports show settlement batches, fee details, export files, payout status, and reconciliation references available to the account.

Trust

Security and account access

Are Member and Operations accounts separate?

Yes. Merchants use the Member login, while protected internal operations use a separate entry point and role-based access controls.

Should card details be stored by the merchant?

No. Use hosted checkout or provider tokenization to keep sensitive payment details outside the merchant application and reduce PCI scope.
