# POST /v1/cdp/audiences/{audience_id}/refresh

> Work out who is in an audience again, now.

Works out who is in an audience again, now, rather than waiting for what people do to change it. It is `building` until done.

<Note>Needs the `cdp.audiences:write` scope.</Note>

## Path parameters

| Field | Type | Required | Notes |
| :- | :- | :- | :- |
| `audience_id` | string | Yes | The audience's id. |

    },
  });
  console.log(response.status, await response.json());
  ```
</CodeGroup>

## Response

`202 Accepted` — the audience, `building`, without its rules. `members` is the count from before until it is done.

```json theme={null}
{
  "id": "5b2e8d14-7c3a-4f9e-a1d6-3e8b0c4f2a71",
  "name": "Carts left this week",
  "description": "Added to cart in the last 7 days and didn't order",
  "status": "building",
  "error": "",
  "members": 312,
  "refreshed_at": "2026-10-06T10:15:02+05:30",
  "created_at": "2026-09-22T11:04:37+05:30",
  "updated_at": "2026-10-01T16:20:45+05:30"
}
```

## Errors

Every refusal is `{"error": {"code", "message", "field"}}`; `field` is there when one input is at fault.

| Status | Error code | When |
| :- | :- | :- |
| 404 | `not_found` | No audience of this account's has that id. |
| 403 | `scope_missing` | The key doesn't have the `cdp.audiences:write` scope. |
| 404 | `module_off` | The account doesn't have Customer data on. |

Any request can also be refused for its key, its account or its rate (`key_required`, `invalid_key`, `account_suspended`, `plan_excludes_api`, `address_not_allowed`, `rate_limited`); see [the overview](/api-reference/overview).
