# POST /api/external/drops/check-status — Check which drops sold (batch)

> Sale info for a batch of product ids — the polling half of sale tracking.

- Source: https://www.dropfans.io/developers/reference/check-drop-status
- Section: API reference
- OpenAPI: https://www.dropfans.io/developers/openapi.json

Sale info for a batch of product ids — the polling half of sale tracking.

Poll it periodically (every few minutes is plenty) with the productIds you are tracking. Amounts are gross buyer-paid totals in **cents**.

> [!WARNING] Truncation, omission, refunds
> At most 200 ids are processed per call — extras are **dropped without an error**, so chunk larger lists. Unsold and unknown ids are **omitted** from the response (only `paid: true` entries appear). And unlike earnings, this endpoint does **NOT exclude refunded or charged-back orders** — a refunded sale still reports paid. Reconcile against [GET /api/external/earnings](https://www.dropfans.io/developers/reference/get-earnings.md) for net truth.

## Authentication

`Authorization: Bearer dpfn_...` — an API key generated in the creator's dashboard (Vault → API Connect). One key = one creator. Missing or invalid keys return 401 `{"error":"Unauthorized","code":"unauthorized"}`.

## Request body (application/json)

| Field | Type | Required | Description |
|---|---|---|---|
| `productIds` | string[] | yes | Product ids to check (≤200 — extras silently dropped). Non-strings filtered out; an empty array returns {"sales":{}}. |

Example — Check two drops:

```json
{
  "productIds": [
    "clxdr0p000001prod",
    "clxdr0p000002prod"
  ]
}
```

## Responses

### 200

Sales map — only sold products appear. Multiple paid orders on one product report the most recent.

| Field | Type | Required | Description |
|---|---|---|---|
| `sales` | SalesMap | yes | productId → most recent sale. |

```json
{
  "sales": {
    "clxdr0p000001prod": {
      "paid": true,
      "saleAmountCents": 2500,
      "buyerEmail": "buyer@example.com"
    }
  }
}
```

## Errors

| Status | Body | When |
|---|---|---|
| 400 | `{"error":"Invalid JSON body"}` | The body is not valid JSON. |
| 401 | `{"error":"Unauthorized","code":"unauthorized"}` | Missing or invalid API key. |
| 500 | `{"error":"Failed to check drop status"}` | Query failed — retry later. |

## Rate limiting

Per-key fixed windows by tier (Personal 60/min · 5,000/day; approved apps 300/min · 50,000/day; Dropfans-operated integrations exempt). Read the live values from X-RateLimit-Tier, X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset and their -Day variants; a 429 carries Retry-After and `{"error":"Rate limit exceeded","code":"rate_limited"}`. See [Rate limits](https://www.dropfans.io/developers/concepts/rate-limits.md).
