Admin API

The Admin API lets you manage your organization's members, workspaces, invites, and API keys programmatically instead of by hand in the Claude Console.

Authentication

Authenticate with any of the three credentials. An Admin API key covers most endpoints. The service-account, federation-issuer, and federation-rule endpoints accept only an org:admin OAuth token. Send a personal key or service account key in the x-api-key header, as you would an Admin API key. The following examples call the organization info endpoint with an OAuth token and with an Admin API key.

The Python, TypeScript, C#, Go, Java, PHP, and Ruby SDKs expose the endpoints on this page under client.organization, and the ant CLI under ant organization. The examples on this page use the default client, which reads an Admin API key from ANTHROPIC_API_KEY or an OAuth bearer token from ANTHROPIC_AUTH_TOKEN. SDK list methods in Python, TypeScript, C#, Go, and Java return an iterator that fetches more pages on demand, so limit sets the page size, not the total. The PHP, Ruby, and curl examples return one page. In the CLI, --limit caps the results on the member, invite, workspace, workspace-member, and API-key lists. For each endpoint's parameters and responses, see the Admin API reference.

OAuth bearer token

Log in with the ant CLI under a dedicated profile with the org:admin scope (see Admin access), then export the bearer token. --profile admin stores the org:admin credential under its own profile and makes it the CLI's active profile. The exported variable applies to every SDK and CLI call in that shell. Use a shell you reserve for administration, unset the variable when you're done, and switch the CLI back with ant profile activate default:

ant auth login --profile admin --scope "org:admin"
export ANTHROPIC_AUTH_TOKEN=$(ant auth print-credentials --profile admin --access-token)

Interactive tokens are short-lived. If requests start returning 401, re-run the export command to refresh the token.

The SDKs and the ant CLI read ANTHROPIC_AUTH_TOKEN automatically. Leave ANTHROPIC_API_KEY unset in the same shell so they send the bearer token. Automated workloads skip the login: they authenticate through workload identity federation, and the SDKs and CLI perform the token exchange from the federation environment variables. See Bootstrap a workload to manage WIF.

Call the Admin API with the exported token:

client = anthropic.Anthropic()

organization = client.organization.retrieve()

print(f"id: {organization.id}")
print(f"name: {organization.name}")

An org:admin token grants access to the whole organization, regardless of the workspace the underlying profile or federation rule is bound to.

For CI and other non-interactive workloads, mint the token with Workload Identity Federation instead of logging in interactively. See Manage WIF with the Admin API.
