The practical overview
A gateway connects an online payment experience to the processing path. Compatibility affects checkout, tokenization, subscriptions, refunds, fraud tools, webhooks, and reconciliation.
What to look for
- Confirm storefront or application compatibility.
- Prefer hosted or tokenized payment components.
- Plan webhook verification and failure handling.
- Map refunds, disputes, and order reconciliation.
Questions worth asking
Ask who owns the gateway account, which integrations are supported, how data exports work, and what changes if the processor or platform changes.
A responsible next step
Review the technical and business requirements together before choosing a gateway.
