In-App Checkout Options (Windows)

Overriding Prices

To override prices in the checkout you can use the PriceOverrides property in the CheckoutOptions class. You’ll need to supply an auth hash, this is a MD5 hash of the new product price concatenated with the ‘Checkout Secret Key’ from your dashboard for that product


// Create new price overrides for your product
PriceOverride priceUSD = new PriceOverride()
{
    Price = "7.99",
    Currency = "USD",
    Authorization = ""
};
PriceOverride priceGBP = new PriceOverride()
{
    Price = "6.99",
    Currency = "GBP",
    Authorization = ""
};

// Create a new CheckoutOptions instance and add your price overrides
CheckoutOptions options = new CheckoutOptions();

options.PriceOverrides.AddPrice(priceUSD);
options.PriceOverrides.AddPrice(priceGBP);

// Pass the CheckoutOptions object when you open the CheckoutWindow
Paddle.Instance.ShowCheckoutWindowForProduct(product, options);

Pre-fill Checkout Fields

You can also pre-fill certain checkout fields such as the Email and the PostCode by setting their appropriate properties in the CheckoutOptions object.


// Create a new CheckoutOptions instance and set the properties you want to pre-fill
CheckoutOptions options = new CheckoutOptions();

options.Email = "example@email.com";
options.Country = "us";
options.PostCode = "SE1";
options.Coupon = "My-coupon";

// Pass the CheckoutOptions object when you open the CheckoutWindow
Paddle.Instance.ShowCheckoutWindowForProduct(product, options);

Custom Parameters

If you need pass additional Custom Checkout parameters you can also use the CheckoutOptions.AddCheckoutParameters() method.


// Create a new CheckoutOptions instance and add the custom parameters you need
CheckoutOptions options = new CheckoutOptions();

options.AddCheckoutParameters("custom_message", "A short message displayed below the product name on the checkout.");

// Pass the CheckoutOptions object when you open the CheckoutWindow
Paddle.Instance.ShowCheckoutWindowForProduct(product, options);
