# [BETA] Create a signal endpoint.

POST https://app.unleash-instance.example.com/api/admin/signal-endpoints
Content-Type: application/json

**Enterprise feature**

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

Creates a new signal endpoint.

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

## 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

### Body (application/json)

- `name` (string, required) — The signal endpoint name. Must be URL-safe.
- `enabled` (boolean, optional) — Whether the signal endpoint is currently enabled. If not specified, defaults to true.
- `description` (string, optional, nullable) — A more detailed description of the signal endpoint and its intended use.

## Response

### 201

The resource was successfully created.

- `id` (integer, required) — The signal endpoint's ID. Signal endpoint IDs are incrementing integers. In other words, a more recently created signal endpoint will always have a higher ID than an older one.
- `enabled` (boolean, required) — Whether the signal endpoint is currently enabled. If not specified, defaults to true.
- `name` (string, required) — The signal endpoint name. Must be URL-safe.
- `createdAt` (string, required) — The date and time of when the signal endpoint was created.
- `createdByUserId` (integer, required) — The ID of the user that created this signal endpoint.
- `description` (string, optional, nullable) — A more detailed description of the signal endpoint and its intended use.
- `url` (string, optional) — The full URL that should be used to call the signal endpoint. This property is only returned for newly created or updated signal endpoints.
- `tokens` (list of object, optional) — The list of tokens associated with the signal endpoint.
  - `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.
