# List leads for a single form

`GET /v1/ads/lead-forms/{formId}/leads`

Returns leads for one form. Serves persisted leads (ingested via the leadgen webhook) when available, falling back to a live Graph read. Accepts a Facebook account or a metaads business-login account with leads_retrieval access to the form; the latter uses its system-user token without a posting parent.

## Path parameters

- `formId` string, required

## Query parameters

- `accountId` string, required
- `limit` integer
- `cursor` string
- `since` integer

## Response `200`

Leads for the form.

  - `status` string
  - `leads` object[]
    - `id` string
    - `createdTime` string, nullable
    - `adId` string, nullable
    - `formId` string
    - `fields` object
    - `fieldData` object[]
  - `pagination` object
    - `hasMore` boolean
    - `cursor` string, nullable

## Other responses

- `400` — Invalid request
- `401` — Unauthorized
- `404` — The account or requested resource was not found or is not accessible. An account ID may have been disconnected and removed. Read GET /v1/accounts for current account IDs.
- `409` — The account exists but is inactive or needs reconnection. Reconnect it, then read GET /v1/accounts for its current account ID before retrying. Code: ads_connection_required.
