What is your experience with payment platforms and payment processing systems?

Experience with payment platforms typically includes integration with APIs for processing payments, managing transactions, security, and error handling.

For example, when working with payment systems (Stripe, PayPal, Yandex.Kassa, etc.), it is important:

• To use SDKs or REST APIs for creating payments, refunds, and status checks.
• To ensure data security by using encryption and complying with PCI DSS standards.
• To handle asynchronous notifications (webhooks) for updating payment statuses.
• To log operations for auditing and debugging.

In Go, this might look like (a simplified example of creating a payment via REST API):

package main

import (
    "bytes"
    "encoding/json"
    "net/http"
    "log"
)

type PaymentRequest struct {
    Amount   int    `json:"amount"`
    Currency string `json:"currency"`
    Source   string `json:"source"`
}

func createPayment() {
    payment := PaymentRequest{Amount: 1000, Currency: "USD", Source: "tok_visa"}
    body, _ := json.Marshal(payment)

    resp, err := http.Post("https://api.paymentprovider.com/payments", "application/json", bytes.NewBuffer(body))
    if err != nil {
        log.Fatal(err)
    }
    defer resp.Body.Close()

    // Handle response...
}

func main() {
    createPayment()
}

This experience requires understanding protocols, security, and the specifics of the particular platform.
