# Method name: previewPrice(planId: string, couponCode: string)

# Method package: wixPricingPlansBackend

# Method menu location: wixPricingPlansBackend --> Checkout --> previewPrice

# Method Link: https://dev.wix.com/docs/velo/apis/wix-pricing-plans-backend/checkout/preview-price.md

# Method Description:

Provides a preview of an order's pricing as if was purchased.

The `previewPrice()` function returns a Promise that resolves to a temporary preview of the order's price.

 The price preview uses the same logic for calculating prices as used when purchasing a plan, but the preview is not saved.
 If [taxes are configured for the site](https://support.wix.com/en/article/pricing-plans-setting-up-tax-collection), taxes are applied to the preview.  If not, the `tax` previews as `null`.

 Buyers do not have to be logged in to preview the price, as such, the details returned by this function are not buyer-specific. To generate
 a preview of a purchase for a specific buyer, use the [previewOfflineOrder()](wix-pricing-plans-backend/checkout/preview-offline-order) or [previewOnlineOrder()](wix-pricing-plans-backend/checkout/preview-online-order) functions.



# Method Code Examples:

*** Note: do not assume any prop names or enum values other than the ones in the example.

## Preview the pricing details for a plan to be purchased with a 10%-off coupon

```javascript
import { Permissions, webMethod } from 'wix-web-module';
import { checkout } from 'wix-pricing-plans-backend';

// Sample planId value: '6d7537c5-beac-44a3-bea3-b947ddc56b31'
//
// Sample couponCode value: 'BACKTOSHAPE22'

export const myPreviewPriceFunction = webMethod(Permissions.Anyone, async (planId, couponCode) => {
  try {
    const pricePreview = await checkout.previewPrice(planId, couponCode);
    const orderPricing = pricePreview.prices.price.total;
    const currency = pricePreview.prices.price.currency;

    return pricePreview;
  } catch (error) {
    console.error(error);
  }
});
