How do I call Stripe APIs securely in Go?

To securely call Stripe APIs in Go, you need to follow a few best practices to ensure that your API keys and data are handled safely. Here’s a concise example of how you can make secure API requests to Stripe using the official Go client library.

First, you need to install the Stripe Go client:

go get -u github.com/stripe/stripe-go

Next, initialize your Stripe client with your secret API key. It is important to retrieve this API key from a safe location, such as environment variables, instead of hardcoding it in your source code.

Here’s a simple example:

package main

import (
    "fmt"
    "os"

    "github.com/stripe/stripe-go/v72"
    "github.com/stripe/stripe-go/v72/customer"
)

func main() {
    // Set your secret key from an environment variable
    stripe.Key = os.Getenv("STRIPE_SECRET_KEY")

    // Create a new customer
    params := &stripe.CustomerParams{
        Email: stripe.String("customer@example.com"),
    }
    newCustomer, err := customer.New(params)
    if err != nil {
        fmt.Println("Error creating customer:", err)
        return
    }

    fmt.Println("Customer created successfully:", newCustomer.ID)
}

Don't forget to handle errors and always secure your API keys. Use environment variables or a secure secrets management service to store sensitive information.
