/** |
| 3 |
* GatewayAdapter — single contract for client-side payment-intent creation. |
| 4 |
* |
| 5 |
* Each payment gateway (Stripe, PayPal, Square, Razorpay, …) optionally |
| 6 |
* implements this interface so both the traditional /checkout/ page (vanilla JS) |
| 7 |
* and the embedded React checkout can share one REST endpoint |
| 8 |
* (`POST /storeengine/v1/checkout/payment-intent/{gateway_id}`) for |
| 9 |
* pre-confirmation client-side flows (Stripe PaymentIntents, PayPal order |
| 10 |
* creation, etc.). |
| 11 |
* |
| 12 |
* For gateways that don't need a client-confirmation step (offline / COD), |
| 13 |
* implementing this interface is unnecessary — the place_order endpoint runs |
| 14 |
* gateway->process_payment() directly. |
| 15 |
