List External Keys

GET /v1/organizations/external_keys

List external key configs in the caller's organization.

Results are ordered by creation time (newest first). Use the next_page cursor from the response to fetch subsequent pages.

Query parameters

• limit: optional number

  Number of results per page.

  default: 20, maximum: 100, minimum: 1

• page: optional string

  Opaque cursor from a previous response's next_page.

Returns

• data: array of BetaExternalKey

  • type: "external_key"

    default: external_key

  • id: string

    Identifier of the external key config. A tagged ID prefixed ekey_, or — for organizations on the Claude Platform on AWS — the AWS KMS key ARN.

  • attachment: BetaExternalKeyAttachedAttachment or BetaExternalKeyUnattachedAttachment

    Whether any workspace uses this config to encrypt its data — counting live and archived workspaces (an archived workspace's data remains encrypted under the config), excluding deleted ones. Only an attached config is used by the encryption path; an unattached config is inert and can be deleted.

    • BetaExternalKeyAttachedAttachment object

      • type: "attached"

        default: attached

    • BetaExternalKeyUnattachedAttachment object

      • type: "unattached"

        default: unattached

  • created_at: string

    format: date-time

  • display_name: string or null

    Human-friendly display name. Null if none was set.

  • geo: string

    Data residency geo. Selects which regional validator handles this key's encrypt/decrypt roundtrips.

  • provider_config: BetaAWSExternalKeyConfig or BetaGCPExternalKeyConfig or BetaAzureExternalKeyConfig

    KMS provider identity and auth coordinates.

    • BetaAWSExternalKeyConfig object

      • type: "aws"

      • kms_arn: string

        Full ARN of the AWS KMS key. On Claude Platform on AWS the key must be a single-Region key in your organization's own AWS account; cross-account keys, multi-Region keys, and alias ARNs are rejected.

        maxLength: 2048

      • region: optional string or null

        AWS region. Derived from kms_arn if omitted.

      • role_arn: optional string or null

        Deprecated

        IAM role ARN. Deprecated — Anthropic reaches the KMS key through its own intermediate role (or, on Claude Platform on AWS, with credentials AWS issues for the Workspace); this field is ignored.

    • BetaGCPExternalKeyConfig object

      • type: "gcp"

      • key_name: string

        Full resource name of the Cloud KMS key.

    • BetaAzureExternalKeyConfig object

      • type: "azure"

      • key_name: string

        Name of the key within the vault.

      • tenant_id: string

        Azure AD tenant ID.

      • vault_uri: string

        Key Vault data-plane URI — https://\{vault-name\}.vault.azure.net or https://\{hsm-name\}.managedhsm.azure.net.

      • client_id: optional string or null

        Azure AD application (client) ID. Omit to use Anthropic's multitenant app. Provide only if using a single-tenant app registration in the customer's directory.

  • updated_at: string

    format: date-time

• next_page: string or null

  Opaque cursor for the next page, or null if no more results. Pass as ?page= to fetch the next page.
