# createCartWorkflow - Medusa Core Workflows Reference

This documentation provides a reference to the `createCartWorkflow`. It belongs to the `@medusajs/medusa/core-flows` package.

This workflow creates and returns a cart. You can set the cart's items, region, customer, and other details. This workflow is executed by the
[Create Cart Store API Route](https://docs.medusajs.com/api/store/carts/create-cart).

This workflow has a hook that allows you to perform custom actions on the created cart. You can see an example in [this guide](https://docs.medusajs.com/resources/commerce-modules/cart/extend#step-4-consume-cartcreated-workflow-hook).

You can also use this workflow within your customizations or your own custom workflows, allowing you to wrap custom logic around cart creation.

## Steps

- [findSalesChannelStep](https://docs.medusajs.com/references/medusa-workflows/steps/findSalesChannelStep): This step either retrieves a sales channel either using the ID provided as an input, or, if no ID is provided, the default sales channel of the first store.
- [findOneOrAnyRegionStep](https://docs.medusajs.com/references/medusa-workflows/steps/findOneOrAnyRegionStep): This step retrieves a region either by the provided ID or the first region in the first store.
- [findOrCreateCustomerStep](https://docs.medusajs.com/references/medusa-workflows/steps/findOrCreateCustomerStep): This step finds or creates a customer based on the provided ID or email. It prioritizes finding the customer by ID, then by email. The step creates a new customer either if: - No customer is found with the provided ID and email; - Or if it found the customer by ID but their email does not match the email in the input. The step returns the details of the customer found or created, along with their email.
  - [setPricingContext](#setPricingContext): This hook is executed after the order is retrieved and before the line items are created. You can consume this hook to return any custom context useful for the prices retrieval of the variants to be added to the order. For example, assuming you have the following custom pricing rule: ```json { "attribute": "location_id", "operator": "eq", "value": "sloc_123", } ``` You can consume the `setPricingContext` hook to add the `location_id` context to the prices calculation: ```ts import { addOrderLineItemsWorkflow } from "@medusajs/medusa/core-flows"; import { StepResponse } from "@medusajs/workflows-sdk"; addOrderLineItemsWorkflow.hooks.setPricingContext(( { order, variantIds, region, customerData, additional_data }, { container } ) => { return new StepResponse({ location_id: "sloc_123", // Special price for in-store purchases }); }); ``` The variants' prices will now be retrieved using the context you return. :::note Learn more about prices calculation context in the [Prices Calculation](https://docs.medusajs.com/resources/commerce-modules/pricing/price-calculation) documentation. :::
    - [confirmVariantInventoryWorkflow](https://docs.medusajs.com/references/medusa-workflows/confirmVariantInventoryWorkflow): Validate that a variant is in-stock before adding to the cart.
      - [prepareCartToCreateStep](https://docs.medusajs.com/references/medusa-workflows/prepareCartToCreateStep): This step prepares the data used to create a cart, resolving the cart's currency, region, customer, sales channel, and a default shipping address when the region has a single country. It throws an error if no region is provided.
        - [getTranslatedLineItemsStep](https://docs.medusajs.com/references/medusa-workflows/steps/getTranslatedLineItemsStep): This step translates cart line items based on their associated variant and product IDs. It fetches translations for the product (title, description, subtitle) and variant (title), then applies them to the corresponding line item fields.
          - [validate](#validate): This hook is executed before all operations. You can consume this hook to perform any custom validation. If validation fails, you can throw an error to stop the workflow execution.
            - [createCartsStep](https://docs.medusajs.com/references/medusa-workflows/steps/createCartsStep): This step creates a cart.
              - [updateTaxLinesWorkflow](https://docs.medusajs.com/references/medusa-workflows/updateTaxLinesWorkflow): Update a cart's tax lines.
                - [updateCartPromotionsWorkflow](https://docs.medusajs.com/references/medusa-workflows/updateCartPromotionsWorkflow): Update a cart's applied promotions to add, replace, or remove them.
                  - [refreshPaymentCollectionForCartWorkflow](https://docs.medusajs.com/references/medusa-workflows/refreshPaymentCollectionForCartWorkflow): Refresh a cart's payment collection details.
                  - [emitEventStep](https://docs.medusajs.com/references/medusa-workflows/steps/emitEventStep): This step emits an event, which you can listen to in a [subscriber](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers). You can pass data to the subscriber by including it in the `data` property. The event is only emitted after the workflow has finished successfully. So, even if it's executed in the middle of the workflow, it won't actually emit the event until the workflow has completed successfully. If the workflow fails, it won't emit the event at all.

## Hooks

Hooks allow you to inject custom functionalities into the workflow. You'll receive data from the workflow, as well as additional data sent through an HTTP request.

Learn more about [Hooks](https://docs.medusajs.com/learn/fundamentals/workflows/workflow-hooks) and [Additional Data](https://docs.medusajs.com/learn/fundamentals/api-routes/additional-data).

### setPricingContext

This hook is executed after the cart is retrieved and before the line items are created. You can consume this hook to return any custom context useful for the prices retrieval of the variants to be added to the cart.

For example, assuming you have the following custom pricing rule:

```json
{
  "attribute": "location_id",
  "operator": "eq",
  "value": "sloc_123",
}
```

You can consume the `setPricingContext` hook to add the `location_id` context to the prices calculation:

```ts
import { createCartWorkflow } from "@medusajs/medusa/core-flows";
import { StepResponse } from "@medusajs/workflows-sdk";

createCartWorkflow.hooks.setPricingContext((
  { region, variantIds, salesChannel, customerData, additional_data }, { container }
) => {
  return new StepResponse({
    location_id: "sloc_123", // Special price for in-store purchases
  });
});
```

The variants' prices will now be retrieved using the context you return.

> **Note**
>
> Learn more about prices calculation context in the [Prices Calculation](https://docs.medusajs.com/resources/commerce-modules/pricing/price-calculation) documentation.

#### Example

```ts
import { createCartWorkflow } from "@medusajs/medusa/core-flows"

createCartWorkflow.hooks.setPricingContext(
  (async ({ region, variantIds, salesChannel, customerData,
    additional_data }, { container }) => {
    //TODO
  })
)
```

#### Input

Handlers consuming this hook accept the following input.

**setPricingContext**

    - `__step__`: `string`
  - `additional_data`: `Record<string, unknown> | undefined` — Additional data that can be passed through the `additional_data` property in HTTP requests. Learn more in [this documentation](https://docs.medusajs.com/learn/fundamentals/api-routes/additional-data).

### validate

#### Example

```ts
