# Method name: previewPrice(bookingLineItems: Array<BookingLineItem>)

# Method package: wixBookingsV2

# Method menu location: wixBookingsV2 --> pricing --> previewPrice

# Method Link: https://dev.wix.com/docs/velo/apis/wix-bookings-v2/pricing/preview-price.md

# Method Description:

Previews the base price for a set of line items belonging to the same service
before a potential booking is actually created.



The returned price preview information about each line
item's price and sums up each line item's price.

The previewed price is not the actual price that will be used to charge the customer.
`Preview Price` only estimates the base price by adding up the price
of each line item before
the booking is actually created.

Use [`Calculate Price`](https://www.wix.com/velo/reference/wix-bookings-v2/pricing/calculateprice) to get the base price
after the booking is created.

Passing line items that belong to different services results in an error.

## Calculating the previewed price

Wix Bookings has its own default pricing logic for previewing the price. You must
pass the `serviceId` in the `slot`
or `schedule` object to `previewPrice()`.

You cannot call `previewPrice()` if you have customized Bookings pricing logic using the
[BookingsCustomPricing](https://dev.wix.com/docs/velo/api-reference/wix-bookings-v2/service-plugins-spis/bookings-custom-pricing/introduction.md) service plugin. Calling `previewPrice` if custom pricing
logic has been implemented for the site results in an error.



# Method Code Examples:

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

## previewPrice example

```javascript
import { pricing } from 'wix-bookings.v2';

async function previewPrice(bookingLineItems) {
  try {
    const result = await pricing.previewPrice(bookingLineItems);
    return result;
  } catch (error) {
    console.error(error);
    // Handle the error
  }
}

```

## previewPrice example for exporting from backend code

```javascript
import { pricing } from 'wix-bookings.v2';
import { webMethod, Permissions } from 'wix-web-module';

export const previewPrice = webMethod(
  Permissions.Anyone,
  async (bookingLineItems) => {
    try {
      const result = await pricing.previewPrice(bookingLineItems);
      return result;
    } catch (error) {
      console.error(error);
      // Handle the error
    }
  }
);

```
