An OrderProcess is used to define the way the order process works as in: what states an Order can be
in, and how it may transition from one state to another. Using the `onTransitionStart()` hook, an
OrderProcess can perform checks before allowing a state transition to occur, and the `onTransitionEnd()`
hook allows logic to be executed after a state change.

For detailed description of the interface members, see the <DocsLink href="/reference/typescript-api/state-machine/state-machine-config#statemachineconfig">StateMachineConfig</DocsLink> docs.

:::info

This is configured via the `orderOptions.process` property of
your VendureConfig.

Options which can be passed to the <DocsLink href="/reference/typescript-api/orders/order-process#configuredefaultorderprocess">configureDefaultOrderProcess</DocsLink> function
to configure an instance of the default <DocsLink href="/reference/typescript-api/orders/order-process#orderprocess">OrderProcess</DocsLink>. By default, all
options are set to `true`.

```ts title="Signature"
interface DefaultOrderProcessOptions {
    checkModificationPayments?: boolean;
    checkAdditionalPaymentsAmount?: boolean;
    checkAllVariantsExist?: boolean;
    arrangingPaymentRequiresContents?: boolean;
    arrangingPaymentRequiresCustomer?: boolean;
    arrangingPaymentRequiresShipping?: boolean;
    arrangingPaymentRequiresStock?: boolean;
    checkPaymentsCoverTotal?: boolean;
    checkAllItemsBeforeCancel?: boolean;
    checkFulfillmentStates?: boolean;
}
```

<div className="members-wrapper">

### checkModificationPayments

<MemberInfo kind="property" type={`boolean`} default={`true`}   />

Prevents an Order from transitioning out of the `Modifying` state if
the Order price has changed and there is no Payment or Refund associated
with the Modification.
### checkAdditionalPaymentsAmount

<MemberInfo kind="property" type={`boolean`} default={`true`}   />

Prevents an Order from transitioning out of the `ArrangingAdditionalPayment` state if
the Order's Payments do not cover the full amount of `totalWithTax`.
### checkAllVariantsExist

<MemberInfo kind="property" type={`boolean`} default={`true`}   />

Prevents the transition from `AddingItems` to any other state (apart from `Cancelled`) if
and of the ProductVariants no longer exists due to deletion.
### arrangingPaymentRequiresContents

<MemberInfo kind="property" type={`boolean`} default={`true`}   />

Prevents transition to the `ArrangingPayment` state if the active Order has no lines.
### arrangingPaymentRequiresCustomer

<MemberInfo kind="property" type={`boolean`} default={`true`}   />

Prevents transition to the `ArrangingPayment` state if the active Order has no customer
associated with it.
### arrangingPaymentRequiresShipping

<MemberInfo kind="property" type={`boolean`} default={`true`}   />

Prevents transition to the `ArrangingPayment` state if the active Order has no shipping
method set.
### arrangingPaymentRequiresStock

<MemberInfo kind="property" type={`boolean`} default={`true`}   />

Prevents transition to the `ArrangingPayment` state if there is insufficient saleable
stock to cover the contents of the Order.
### checkPaymentsCoverTotal

<MemberInfo kind="property" type={`boolean`} default={`true`}   />

Prevents transition to the `PaymentAuthorized` or `PaymentSettled` states if the order
`totalWithTax` amount is not covered by Payment(s) in the corresponding states.
### checkAllItemsBeforeCancel

<MemberInfo kind="property" type={`boolean`} default={`true`}   />

Prevents transition to the `Cancelled` state unless all OrderItems are already
cancelled.
### checkFulfillmentStates

<MemberInfo kind="property" type={`boolean`} default={`true`}   />

Prevents transition to the `Shipped`, `PartiallyShipped`, `Delivered` & `PartiallyDelivered` states unless
there are corresponding Fulfillments in the correct states to allow this. E.g. `Shipped` only if all items in
the Order are part of a Fulfillment which itself is in the `Shipped` state.

<GenerationInfo sourceFile="packages/core/src/config/order/default-order-process.ts" sourceLine="163" packageName="@vendure/core" since="2.0.0" />

Used to configure a customized instance of the default <DocsLink href="/reference/typescript-api/orders/order-process#orderprocess">OrderProcess</DocsLink> that ships with Vendure.
Using this function allows you to turn off certain checks and constraints that are enabled by default.

```ts
import { configureDefaultOrderProcess, VendureConfig } from '@vendure/core';

const myCustomOrderProcess = configureDefaultOrderProcess({
  // Disable the constraint that requires
  // Orders to have a shipping method assigned
  // before payment.
  arrangingPaymentRequiresShipping: false,
});

export const config: VendureConfig = {
  orderOptions: {
    process: [myCustomOrderProcess],
  },
};
```
The <DocsLink href="/reference/typescript-api/orders/order-process#defaultorderprocessoptions">DefaultOrderProcessOptions</DocsLink> type defines all available options. If you require even
more customization, you can create your own implementation of the <DocsLink href="/reference/typescript-api/orders/order-process#orderprocess">OrderProcess</DocsLink> interface.

```ts title="Signature"
function configureDefaultOrderProcess(options: DefaultOrderProcessOptions): void
```
Parameters

### options

<GenerationInfo sourceFile="packages/core/src/config/order/default-order-process.ts" sourceLine="475" packageName="@vendure/core" since="2.0.0" />

This is the built-in <DocsLink href="/reference/typescript-api/orders/order-process#orderprocess">OrderProcess</DocsLink> that ships with Vendure. A customized version of this process
can be created using the <DocsLink href="/reference/typescript-api/orders/order-process#configuredefaultorderprocess">configureDefaultOrderProcess</DocsLink> function, which allows you to pass in an object
to enable/disable certain checks.

<GenerationInfo sourceFile="packages/core/src/service/helpers/order-state-machine/order-state.ts" sourceLine="21" packageName="@vendure/core" since="2.0.0" />

An interface to extend the <DocsLink href="/reference/typescript-api/orders/order-process#orderstate">OrderState</DocsLink> type.

```ts title="Signature"
interface OrderStates {

}
```
<GenerationInfo sourceFile="packages/core/src/service/helpers/order-state-machine/order-state.ts" sourceLine="42" packageName="@vendure/core" />

These are the default states of the Order process. They can be augmented and
modified by using the <DocsLink href="/reference/typescript-api/orders/order-options#orderoptions">OrderOptions</DocsLink> `process` property, and by default
the <DocsLink href="/reference/typescript-api/orders/order-process#defaultorderprocess">defaultOrderProcess</DocsLink> will add the states

- `ArrangingPayment`
- `PaymentAuthorized`
- `PaymentSettled`
- `PartiallyShipped`
- `Shipped`
- `PartiallyDelivered`
- `Delivered`
- `Modifying`
- `ArrangingAdditionalPayment`

```ts title="Signature"
type OrderState = | 'Created'
    | 'Draft'
    | 'AddingItems'
    | 'Cancelled'

    | keyof OrderStates

<GenerationInfo sourceFile="packages/core/src/service/helpers/order-state-machine/order-state.ts" sourceLine="57" packageName="@vendure/core" />

This is the object passed to the <DocsLink href="/reference/typescript-api/orders/order-process#orderprocess">OrderProcess</DocsLink> state transition hooks.

    ctx: RequestContext;
    order: Order;
