# linkSellersToProductCategoryWorkflow

> Add or remove seller eligibility links on a product category.

Updates which sellers are allowed to sell in a product category by creating and removing seller–category links in one call — the mechanism behind restricted categories. Triggered by `POST /admin/product-categories/:id/sellers`. No events are emitted.

## Usage

```ts theme={null}
import { linkSellersToProductCategoryWorkflow } from "@mercurjs/core/workflows"

await linkSellersToProductCategoryWorkflow(container).run({
  input: {
    id: "pcat_01H...",
    add: ["sel_01H..."],
    remove: ["sel_01J..."],
  },
})
```

## Input

<ParamField body="id" type="string" required>
  Id of the product category whose seller links are being updated.
</ParamField>

<ParamField body="add" type="string[]">
  Seller ids to link to the category.
</ParamField>

<ParamField body="remove" type="string[]">
  Seller ids to unlink from the category.
</ParamField>

## Result

<ResponseField name="result" type="void">
  Returns nothing; the links are created and removed in place.
</ResponseField>
