# Delete an invoice

`DELETE https://rebaar.in/api/v1/invoices/{id}`

Only a Draft with nothing paid, no IRN and no payment awaiting verification can be deleted — anything else returns 409. An issued invoice is cancelled with PATCH, never deleted (issued documents are audit records).

## Headers

| Header | Value |
|---|---|
| `Authorization` | `Bearer <your API key>` |

## Parameters

| Name | In | Type | Required | Description |
|---|---|---|---|---|
| `id` | path | string | yes | The invoice id, as returned by the list endpoint. |

## Example

```bash
curl -X DELETE 'https://rebaar.in/api/v1/invoices/f1a8c3d5-2e6b-4c9f-a017-3b5d8e2c4f96' \
  -H 'Authorization: Bearer ck_live_xxxxxxxx_…'
```

## Errors every call can return

| Status | Code | Meaning | What to do |
|---|---|---|---|
| 401 | `unauthenticated` | No `Authorization: Bearer …` header was sent. | Send your API key as `Authorization: Bearer ck_live_…` on every request. |
| 401 | `invalid_token` | The key is unknown, revoked or expired — or the company cannot use it. | Check you copied the whole key. Make a new one in Settings → API keys if it was revoked or has expired. |
| 403 | `ip_not_allowed` | The request came from an IP address that is not on the key's allowlist. | Call from an allowed address, or change the key's IP allowlist in Settings → API keys. |
| 402 | `plan_required` | The company is not on the Scale plan, which includes the API. | The Owner moves the company to Scale in Settings → Billing. |
| 402 | `access_expired` | The subscription is not active (trial over, payment failed, cancelled, paused, locked or closing). `reason` says which. | The Owner pays or renews in Settings → Billing; calls work again at once. |
| 429 | — | More than 120 requests in a minute with this key (30 with a sandbox key). | Wait the number of seconds in the `Retry-After` header. Every reply carries `RateLimit-Remaining`, so you can slow down before this happens. |
| 403 | `insufficient_scope` | The key does not carry the scope this method needs: `read` for GET, `write` for POST, PATCH and DELETE. | Make a key with the scope you need in Settings → API keys. |
| 500 | `internal` | Something failed on our side. | Retry with exponential backoff. If it keeps happening, email support@rebaar.in with the time of the call. |
