In this section of the documentation, you will find resources to learn more about the API Key Module and how to use it in your application.

<Note title="Looking for no-code docs?">

Refer to the [Medusa Admin User Guide](!user-guide!/settings/developer) to learn how to manage publishable and secret API keys using the dashboard.

</Note>

Medusa has API-key related features available out-of-the-box through the API Key Module. A [module](!docs!/learn/fundamentals/modules) is a standalone package that provides features for a single domain. Each of Medusa's commerce features are placed in Commerce Modules, such as this API Key Module.

<Note>

Learn more about why modules are isolated in [this documentation](!docs!/learn/fundamentals/modules/isolation).

## API Key Features

- [API Key Types and Management](./concepts/page.mdx): Manage API keys in your store. You can create both publishable and secret API keys for different use cases.
- [Token Verification](./concepts/page.mdx#token-verification): Verify tokens of secret API keys to authenticate users or actions.
- [Revoke Keys](./concepts/page.mdx#api-key-expiration): Revoke keys to disable their use permanently.
- Roll API Keys: Roll API keys by [revoking](/references/api-key/revoke) a key then [re-creating it](/references/api-key/createApiKeys).

## How to Use the API Key Module

In your Medusa application, you build flows around Commerce Modules. A flow is built as a [Workflow](!docs!/learn/fundamentals/workflows), which is a special function composed of a series of steps that guarantees data consistency and reliable roll-back mechanism. 

You can build custom workflows and steps. You can also re-use Medusa's workflows and steps, which are provided by the `@medusajs/medusa/core-flows` package.

For example:

export const highlights = [
  ["12", "Modules.API_KEY", "Resolve the module in a step."]
]

```ts title="src/workflows/create-api-key.ts" highlights={highlights}
import { 
  createWorkflow, 
  WorkflowResponse,
  createStep,
  StepResponse,
} from "@medusajs/framework/workflows-sdk"
import { Modules } from "@medusajs/framework/utils"

const createApiKeyStep = createStep(
  "create-api-key",
  async ({}, { container }) => {
    const apiKeyModuleService = container.resolve(Modules.API_KEY)

    const apiKey = await apiKeyModuleService.createApiKeys({
      title: "Publishable API key",
      type: "publishable",
      created_by: "user_123",
    })

    return new StepResponse({ apiKey }, apiKey.id)
  },
  async (apiKeyId, { container }) => {
    const apiKeyModuleService = container.resolve(Modules.API_KEY)

    await apiKeyModuleService.deleteApiKeys([apiKeyId])
  }
)

export const createApiKeyWorkflow = createWorkflow(
  "create-api-key",
  () => {
    const { apiKey } = createApiKeyStep()

    return new WorkflowResponse({
      apiKey,
    })
  }
)
```

You can then execute the workflow in your custom API routes, scheduled jobs, or subscribers:

<CodeTabs group="resource-types">
  <CodeTab label="API Route" value="api-route">
    
```ts title="src/api/workflow/route.ts" highlights={[["11"], ["12"]]} collapsibleLines="1-6" expandButtonLabel="Show Imports"
import type {
  MedusaRequest,
  MedusaResponse,
} from "@medusajs/framework/http"
import { createApiKeyWorkflow } from "../../workflows/create-api-key"

export async function GET(
  req: MedusaRequest,
  res: MedusaResponse
) {
  const { result } = await createApiKeyWorkflow(req.scope)
    .run()

  res.send(result)
}
```

  </CodeTab>
  <CodeTab label="Subscriber" value="subscriber">
    
```ts title="src/subscribers/user-created.ts" highlights={[["11"], ["12"]]} collapsibleLines="1-6" expandButtonLabel="Show Imports"
import {
  type SubscriberConfig,
  type SubscriberArgs,
} from "@medusajs/framework"
import { createApiKeyWorkflow } from "../workflows/create-api-key"

export default async function handleUserCreated({
  event: { data },
  container,
}: SubscriberArgs<{ id: string }>) {
  const { result } = await createApiKeyWorkflow(container)
    .run()

  console.log(result)
}

export const config: SubscriberConfig = {
  event: "user.created",
}
```

  </CodeTab>
  <CodeTab label="Scheduled Job" value="scheduled-job">
    
```ts title="src/jobs/run-daily.ts" highlights={[["7"], ["8"]]}
import { MedusaContainer } from "@medusajs/framework/types"
import { createApiKeyWorkflow } from "../workflows/create-api-key"

export default async function myCustomJob(
  container: MedusaContainer
) {
  const { result } = await createApiKeyWorkflow(container)
    .run()

  console.log(result)
}

export const config = {
  name: "run-once-a-day",
  schedule: `0 0 * * *`,
}
```

  </CodeTab>
</CodeTabs>
