# Create a New Client Token Version

POST https://api.withpersona.com/api/v1/client-tokens/{client-token-id}/rotate
Content-Type: application/json

Rotates a Client Token by creating a new version without disabling existing versions. A Client Token can have up to five usable versions; disable an existing version before rotating if the limit has been reached. The new version's value is returned in the `included` response data. Copy the value when you create the version, then update your integrations to use it.

Reference: https://docs.withpersona.com/api-reference/client-token-versions/rotate-client-token

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Path parameters

- `client-token-id` (string, required) — The ID of the client token to be rotated.

### Query parameters

- `include` (string, optional) — A comma-separated list of relationship paths. This can be used to customize which related resources will be fully serialized in the `included` key in the response. See [Serialization](https://docs.withpersona.com/serialization#inclusion-of-related-resources) for more details.
- `fields` (map from string to string, optional) — Comma-separated list(s) of attributes to include in the response. This can be used to customize which attributes will be serialized in the response. See [Serialization](https://docs.withpersona.com/serialization#sparse-fieldsets) for more details.

### Headers

- `Key-Inflection` (enum, optional) — Determines casing for the API response.
  - Allowed values: `camel`, `kebab`, `snake`
- `Idempotency-Key` (string, optional) — Ensures the request is idempotent.
- `Persona-Version` (enum, optional) — Server API version. More info on versioning can be found [here](https://docs.withpersona.com/versioning).
  - Allowed values: `2025-12-08`, `2025-10-27`, `2023-01-05`, `2022-09-01`, `2021-08-18`, `2021-07-05`, `2021-02-21`, `2020-05-18`

## Types

### ClientTokensClientTokenIdRotatePostRequestBodyContentApplicationJsonSchemaMeta
