# no-service-mutations-in-api-route - ESLint plugin rules

This rule disallows calling service mutation methods directly from an API route handler.

## Severity

`warn`. This rule is enabled in the [recommended](https://docs.medusajs.com/resources/lint#recommended) preset.

## What it Targets

This rule targets `route.ts` and `route.js` files in your project's `src/api` directory. It reports calls to mutation methods, such as `create`, `update`, or `delete` methods, on a service resolved from the container.

The following code is reported by the rule:

```ts title="src/api/admin/products/route.ts"
export const POST = async (req, res) => {
  const productModule = req.scope.resolve(Modules.PRODUCT)
  await productModule.createProducts(req.body)
  res.status(200).json({})
}
```

Instead, move the mutation into a workflow and run it:

```ts title="src/api/admin/products/route.ts"
export const POST = async (req, res) => {
  await createProductWorkflow(req.scope).run({
    input: req.body,
  })
  res.status(200).json({})
}
```

## Why it's Important

Workflows provide rollback, error handling, and a single place to maintain business logic. Calling service mutations directly in a route bypasses these benefits and makes the logic harder to reuse.

Learn more in the [Workflows documentation](https://docs.medusajs.com/learn/fundamentals/workflows).

## Fixable

This rule isn't auto-fixable.

## Turn it Off

To turn off this rule, set it to `off` in your ESLint configuration:

```ts title="eslint.config.ts"
import { defineConfig } from "eslint/config"
import medusa from "@medusajs/eslint-plugin"

export default defineConfig([
  ...medusa.configs.recommended,
  {
    rules: {
      "@medusajs/no-service-mutations-in-api-route": "off",
    },
  },
])
```

Or disable it for a single line using an inline comment:

```ts
// eslint-disable-next-line @medusajs/no-service-mutations-in-api-route
await productModule.createProducts(req.body)
```
