Create External Key

POST/v1/organizations/external_keys

Create an external key config owned by the caller's organization.

Body

provider_config: BetaAWSExternalKeyConfig { kms_arn, type, region, role_arn } or BetaGCPExternalKeyConfig { key_name, type } or BetaAzureExternalKeyConfigParam { key_name, tenant_id, type, 2 more }

KMS provider identity and auth coordinates.

One of the following:

BetaAWSExternalKeyConfig object{ kms_arn, type, region, role_arn }

kms_arn: string

Full ARN of the AWS KMS key.

maxLength2048

type: "aws"

region: optional string or null

AWS region. Derived from kms_arn if omitted.

role_arn: optional string or null⁠Deprecated

IAM role ARN. Deprecated — Anthropic reaches the KMS key via a managed intermediate role; this field is ignored.

BetaGCPExternalKeyConfig object{ key_name, type }

key_name: string

Full resource name of the Cloud KMS key.

type: "gcp"

BetaAzureExternalKeyConfigParam object{ key_name, tenant_id, type, 2 more }

Azure Key Vault provider configuration.

key_name: string

Name of the key within the vault.

tenant_id: string

Azure AD tenant ID.

type: "azure"

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.

display_name: optional string or null

Human-friendly display name.

maxLength255

minLength1

geo: optional "us"

Data residency geo. Only us is supported.

Returns

BetaExternalKey object{ id, attachment, created_at, 5 more }

CMEK external key config belonging to the caller's organization.

Configs are organization-scoped. Workspaces attach to a config; once any workspace references it, the provider fields become effectively immutable (existing encrypted data needs the config for decrypt).
