# Introduction

The Availability Exceptions API allows you to create and manage availability exceptions for restaurant [operations](https://dev.wix.com/docs/api-reference/business-solutions/restaurants/online-orders/operations/introduction.md). Availability exceptions are time periods during which the restaurant's Wix site can’t fulfill orders for the operation. An availability exception can block all fulfillment methods during the time period, or only specific fulfillment methods.

For example, you could use availability exceptions to:

- Offer pickup only on Valentine's Day, by closing all delivery fulfillment methods on that day.
- Close early on Wednesday, by closing all fulfillment methods after midday that day.
- Close a restaurant over the summer by blocking all fulfillment methods for that date range.

With the Availability Exceptions API, you can create and manage availability exceptions.

## Before you begin

It’s important to note the following points before starting to code:

- In order to use this API, the Wix user must install the Wix Restaurants Orders app. 
- Each availability exception object requires the `operationID` of a restaurant's operation.

## Terminology

- **Fulfillment method:** A method by which a restaurant can serve its customers their orders.
