# List statement periods

GET https://%7BYour_Space_Name%7D.signalwire.com/api/space/billing_statements

Lists the months a statement is available for, newest first. Each entry carries the
path of that month's statement and the formats it can be downloaded in: a closed month
is available as JSON, CSV, and PDF; the current month as JSON and CSV only.

Statements are identified by calendar month rather than by an id. This list is not
paged.

#### Permissions

Authenticate with a [Personal access token](/docs/apis/authorization#personal-access-tokens) whose holder is an owner or admin of the space. A project API token is not accepted on this endpoint, and a Personal access token has no scopes: the holder's role in the space is the whole authorization decision.

Reference: https://signalwire.com/docs/apis/rest/space/billing/list-billing-statements

## Authentication

- `Authorization` header (basic auth, required) — Personal access token authentication for space-wide administration. Send HTTP Basic auth with an empty username and the Personal access token as the password. A Personal access token carries your own authority rather than a project's: it is created from your user menu in the Dashboard, is prefixed `pat_`, and has no scopes. The holder must be an owner or admin of the space named by the subdomain, and the token acts only on that space. Example: ``` Authorization: Basic base64(:pat_...) ```

## Response

### 200

The request has succeeded.

- `data` (list of object, required) — The available months, newest first.
  - `type` (enum, required) — The object type. Always `billing_statement_period`.
    - Allowed values: `billing_statement_period`
  - `month` (string, required) — The calendar month the statement covers, as `YYYY-MM`. Statements are identified by month, not by an id.
  - `uri` (string, required) — The path of the statement for this month.
  - `formats` (list of enum, required) — The formats the statement is available in: `json`, `csv`, and `pdf` for a closed month; `json` and `csv` for the current month.
    - Allowed values: `json`, `csv`, `pdf`

## Errors

### 401 Unauthorized Error

The credential is missing, unknown, or revoked; its holder is not a member of the space in the subdomain; the member is not an owner or admin; or billing for this space is not managed in the space itself, which is the case for a space purchased through a cloud marketplace and for a suspended or deactivated space. A space deactivated for nonpayment keeps the billing endpoints so that its outstanding balance can be settled. The body is the plain text `Unauthorized`. An unverified space instead receives the JSON body `{"message": "Please validate a phone number to access your account."}` on every endpoint under `/api/space`.

- `message` (string, required) — States that a phone number must be validated for the space before it can use the API.

### 500 Internal Server Error

An internal server error occurred.

- `error` (enum, required)
  - Allowed values: `Internal Server Error`
