What is payment gateway integration?

Payment gateway integration is the process of connecting an application to payment service providers so it can accept, route and reconcile transactions. Avezone integrates Pakistani rails including Raast, 1LINK, JazzCash, Easypaisa and Safepay alongside Stripe, Adyen and Checkout.com, handling 3D Secure, webhooks, idempotency, refunds, chargebacks and settlement reconciliation.

FAQ

Payment Gateway Integration questions

Answers to what clients ask before committing to this work.

Which payment providers does Avezone integrate?

Avezone integrates Pakistani rails including Raast, 1LINK, JazzCash, Easypaisa and Safepay, plus international providers such as Stripe, Adyen and Checkout.com. Where a business operates across markets, Avezone routes transactions between providers so each payment takes the path with the best authorisation rate and cost.

How do you prevent duplicate charges from webhooks?

Every webhook handler is idempotent, keyed on the provider event identifier, so a retried delivery cannot charge a customer twice. Events are recorded before processing and reconciled against the provider's own ledger on a schedule, which catches the silent mismatches that only surface at month-end otherwise.

Can you improve our authorisation rate?

Often, yes. Declines frequently come from avoidable causes: missing 3D Secure data, poor retry timing, or routing every transaction through one provider. Avezone instruments the payment flow first to find where the losses actually are, then addresses those, rather than assuming the gateway is at fault.

How long does a payment integration take?

A single provider integration with webhooks, refunds and reconciliation typically takes three to five weeks. Multi-provider routing with failover takes longer, usually eight to twelve weeks, because the reconciliation and dispute handling across providers is the substantial part rather than the API calls themselves.
