# Create Subscriber guest token

POST https://%7BYour_Space_Name%7D.signalwire.com/api/fabric/guests/tokens
Content-Type: application/json

Creates a temporary guest [Subscriber](/docs/platform/subscribers) token limited to the resource addresses in `allowed_addresses`. Call it from your server when a user without a full subscriber account needs scoped calling access. The token expires after two hours by default; authenticate this request with a project API token and give only the returned guest token to the client.

Use [Create Subscriber token](/docs/apis/rest/subscribers/tokens/create-subscriber-token) for a known subscriber, or [Create guest embed token](/docs/apis/rest/subscribers/tokens/create-guest-embed-token) when exchanging a public Click-to-Call token.

#### Permissions

The API token used to authenticate must have the following scope(s) enabled to make a successful request: _Voice_, _Messaging_, _Fax_, or _Video_.

[Learn more about API scopes](/docs/platform/your-signalwire-api-space).

Reference: https://signalwire.com/docs/apis/rest/subscribers/tokens/create-subscriber-guest-token

## Authentication

- `Authorization` header (basic auth, required) — SignalWire Basic Authentication using Project ID and API Token. The client sends HTTP requests with the Authorization header containing the word Basic followed by a space and a base64-encoded string of project_id:token. The project ID will be used as the username and the API token as the password. Example: ``` Authorization: Basic base64(project_id:token) ```

## Request

### Body (application/json)

This endpoint expects a SubscriberGuestTokenCreateRequest.

- `allowed_addresses` (list of string, required) — List of up to 10 UUIDs representing the allowed Fabric addresses.
- `expire_at` (integer, optional) — A unixtime (the number of seconds since 1970-01-01 00:00:00) at which the token should no longer be valid. Defaults to 'two hours from now'
- `region` (enum, optional) — A routing override that controls which regional cluster the SDK connects to.
  - Allowed values: `us-central`
- `ch` (enum, optional) — A direct routing override specifying the regional cluster endpoint, set as the `ch` claim in the SAT JWE header.
  - Allowed values: `us-central`

## Response

### 201

The request has succeeded and a new resource has been created as a result.

- `token` (string, required) — Guest Token
