# Supplier cancellation confirmation

> Confirm or reject a supplier-side lead cancellation request.

# Supplier cancellation confirmation

```http theme={null}
POST /api/webhooks/supplier-cancellation-confirmation
```

Used when a **supplier/source** must acknowledge a lead cancellation—not the buyer lifecycle endpoints.

## Auth

Supplier webhook auth derived from the lead’s source configuration.

## Body

```json theme={null}
{
  "leadId": "lead_...",
  "status": "acknowledged",
  "reason": "optional"
}
```

`status`: `acknowledged` | `rejected`.

## Response (conceptual)

```json theme={null}
{
  "accepted": true,
  "code": "lead_cancellation_confirmed",
  "leadId": "...",
  "blockedStatus": "...",
  "alreadyApplied": false,
  "outcome": "confirmed"
}
```

Codes also include `lead_cancellation_rejected` and `lead_already_cancelled`.
