77API keys for the Claude API (also called Anthropic API keys) live in the Claude Console. To view your existing keys or create a new one, go to [Settings → API keys](https://platform.claude.com/settings/keys).

9## Choose a key type
10
11When you create a key, you choose its type, which determines what the key can do, where it works, and when it stops working. A **personal key** acts as you, and stops working if you leave an organization. A **service account key** represents a [service account](https://platform.claude.com/docs/en/manage-claude/workload-identity-federation#service-accounts) which can be used by workloads such as CI pipelines, production services, or agents. Use a personal key for your own development, and a service account key for anything shared.

13You can also create a **workspace key**, a legacy key without an owner: it belongs to the workspace you create it in and keeps working after its creator leaves. It is preferable to use a personal or service account key, as these stop working automatically when their associated account is removed from the organization.

21 Click **Create key**, then give the key a name. You can also choose a [workspace](https://platform.claude.com/settings/workspaces) to scope the key to, and an expiration.
27 Click **Create key**, name the key, choose an [expiration](https://platform.claude.com/docs/en/manage-claude/authentication#key-expiration), and set **Linked account** to yourself or a service account. You can also choose a [workspace](https://platform.claude.com/settings/workspaces) to scope the key to.

29If the **Create key** button is disabled, you may not have permission to create keys in that workspace. Ask an organization admin to grant you access or to create a key for you.
35If the **Create key** button on the API keys page is disabled, your role may not allow you to create keys there. Ask an organization admin to change your role, or to create a service account key for your workload.

39The [client SDKs](https://platform.claude.com/docs/en/cli-sdks-libraries/overview) read `ANTHROPIC_API_KEY` automatically. Direct HTTP requests send the key in the `x-api-key` header. To make your first request, follow the [Quickstart](https://platform.claude.com/docs/en/get-started), and see [Authentication](https://platform.claude.com/docs/en/manage-claude/authentication) for the full picture, including short-lived credentials with Workload Identity Federation.
45The [client SDKs](https://platform.claude.com/docs/en/cli-sdks-libraries/overview) read `ANTHROPIC_API_KEY` automatically. Direct HTTP requests send the key in the `x-api-key` header. If your API key works on multiple workspaces, you must also send the `anthropic-workspace-id` header on each Claude API request, as shown in [Select a workspace](https://platform.claude.com/docs/en/manage-claude/authentication#select-a-workspace). For the Admin API, see [API keys and the Admin API](https://platform.claude.com/docs/en/get-api-key#api-keys-and-the-admin-api).

4149## API keys and the Admin API

43The [Admin API](https://platform.claude.com/docs/en/api/admin) includes endpoints for managing your organization's API keys programmatically, such as [Retrieve API Key](https://platform.claude.com/docs/en/api/admin/api_keys/retrieve) and [List API Keys](https://platform.claude.com/docs/en/api/admin/api_keys/list). These endpoints are for organization admins automating key management. They require a separate [Admin API key](https://platform.claude.com/docs/en/manage-claude/admin-api-keys), and they never return a key's secret value, only a partially redacted hint.

These endpoints are for organization admins automating key management. They accept an [Admin API key](https://platform.claude.com/docs/en/manage-claude/admin-api-keys), an OAuth token with the `org:admin` scope, or a personal or service account key that isn't scoped to a specific workspace; workspace keys don't work there. They never return a key's secret value, only a partially redacted hint.

4654 The Admin API can't recover a lost key or give you a key to call the Claude API with. To get a usable API key, create one in [Settings → API keys](https://platform.claude.com/settings/keys) in the Claude Console.
