Payment Gateway
Service processing credit card transactions.
Why it matters
Payment gateways matter because they influence authorization routing, fraud checks, payment-method presentation, retry behavior, observability, and the reliability of the merchant checkout experience.
How it works
Operationally, the gateway accepts payment details or tokens, applies configuration and risk signals, routes the authorization request, returns the issuer response to the merchant, and may coordinate capture or refund requests depending on the integration.
Risks and pitfalls
The common pitfall is to assume the gateway is the same as processor, acquirer, payment facilitator, or MoR. That confusion hides who owns funds flow, underwriting, disputes, compliance, and customer-facing liability.
Regional notes
In BIST/MOEX/global payment analysis, gateway choice should be separated from local acquiring coverage, currency handling, scheme support, issuer behavior, and regional fraud tooling.
