It belongs to the `@medusajs/medusa/core-flows` package. This workflow refreshes a cart to ensure its prices, promotion codes, taxes, and other details are applied correctly. It's useful after making a chnge to a cart, such as after adding an item to the cart or adding a promotion code. This workflow is used by other cart-related workflows, such as the [addToCartWorkflow](https://docs.medusajs.com/references/medusa-workflows/addToCartWorkflow) after an item is added to the cart. You can use this workflow within your own customizations or custom workflows, allowing you to refresh the cart after making updates to it in your custom flows. > **Note** > > If you use this workflow in another, you must acquire a lock before running it and release the lock after. Learn more in the [Locking Operations in Workflows](https://docs.medusajs.com/learn/fundamentals/workflows/locks#locks-in-nested-workflows) guide.

Learn more about locks in the [Locking Module](https://docs.medusajs.com/resources/infrastructure-modules/locking) guide. - [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. ::: - **when** (when: { return !!input.force_refresh }) - [useQueryGraphStep](https://docs.medusajs.com/references/medusa-workflows/steps/useQueryGraphStep): This step fetches data across modules using the Query.

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 before the cart is refreshed. You can consume this hook to return any custom context useful for the prices retrieval of the variants in 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 { refreshCartItemsWorkflow } from "@medusajs/medusa/core-flows"; import { StepResponse } from "@medusajs/workflows-sdk"; refreshCartItemsWorkflow.hooks.setPricingContext(( { cart, items, 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 { refreshCartItemsWorkflow } from "@medusajs/medusa/core-flows" refreshCartItemsWorkflow.hooks.setPricingContext( (async ({ cart_id, items, additional_data }, { container }) => { //TODO }) ) ``` #### Input Handlers consuming this hook accept the following input. **setPricingContext** - `input`: object — The input data for the hook. - `cart_id`: `string` - `items`: `undefined` \| `any`[] - `additional_data`: `Record | undefined` — Additional data that can be passed through the `additional_data` property in HTTP requests.
