Payment gateway
A payment gateway is the technology layer that connects a merchant's checkout to the payment system: it captures payment details securely, sends them for authorisation, applies fraud checks and 3-D Secure, and returns the approval or decline to the merchant in real time.
What a payment gateway does
A payment gateway is the secure messenger between a merchant's checkout and the payments system. It collects payment details - directly, or through a hosted payment page - encrypts them, runs fraud checks and 3-D Secure authentication, routes the authorisation request to the acquirer, and returns the approval or decline to the merchant's site in real time. Because the gateway handles the card data, it also carries the bulk of the PCI DSS burden that would otherwise fall on the merchant.
Gateway, merchant account, or both
The gateway moves data; the merchant account receives money. A business with its own merchant account can pair it with a gateway of its choice, while a business that wants to start quickly can use a provider that supplies both under one contract. The right answer usually changes over time - many merchants begin on a bundled model and add a direct merchant account as volumes grow.
What separates good gateways
Uptime, approval rates and honest reporting separate working gateways from marketing. Useful questions to ask: which acquirers can it route to, how does it handle 3-D Secure and decline retries, and what does the reconciliation reporting actually show? LekkaPay's gateway connects to Absa, Nedbank, any MPGS-compatible acquirer and any Cybersource-connected bank, with cards, instant EFT, wallets and vouchers behind one integration.
Frequently asked questions
Do I need a merchant account to use a payment gateway?
It depends on the model. A gateway-only arrangement connects your existing merchant account to your checkout, while a full-service provider bundles the gateway with acquiring so you can start without a merchant account of your own. LekkaPay supports both routes, and merchants can move between them without rebuilding the integration.
What is the difference between a gateway and a PSP?
The gateway is the technology layer that moves transaction data securely between checkout, acquirer and card scheme. A payment service provider (PSP) is the broader commercial bundle: gateway technology plus acquiring relationships, alternative payment methods, risk tools and settlement, under one contract.
Can one gateway handle payment methods besides cards?
Yes. A modern gateway presents cards, instant EFT, digital wallets and vouchers through a single integration, returning results in one consistent format regardless of how the customer chose to pay - one set of webhooks, one reconciliation view.
