# [BETA] Update a signal endpoint token.

PUT https://app.unleash-instance.example.com/api/admin/signal-endpoints/{signalEndpointId}/tokens/{id}
Content-Type: application/json

**Enterprise feature**

**[BETA]** This API is in beta state, which means it may change or be removed in the future.

Updates an existing signal endpoint token identified by its id.

Reference: https://docs.getunleash.io/api/update-signal-endpoint-token

## Authentication

- `Authorization` header (required) — API key needed to access this API
- `Authorization` header (bearer token, required) — API key needed to access this API, in Bearer token format

## Request

### Path parameters

- `signalEndpointId` (string, required)
- `id` (string, required)

### Body (application/json)

This endpoint expects a createSignalEndpointTokenSchema.

- `name` (string, required) — The signal endpoint token name.

## Response

### 200

#/components/schemas/signalEndpointTokenSchema

- `id` (integer, required) — The signal endpoint token's ID. Signal endpoint token IDs are incrementing integers. In other words, a more recently created signal endpoint token will always have a higher ID than an older one.
- `name` (string, required) — The signal endpoint token name.
- `signalEndpointId` (integer, required) — The signal endpoint ID that this token belongs to.
- `createdAt` (string, required) — The date and time of when the signal endpoint token was created.
- `createdByUserId` (integer, required) — The ID of the user that created this signal endpoint token.
- `token` (string, optional) — The token used for authentication. It is automatically generated by Unleash when the token is created and that is the only time this property is returned.

## Errors
