# Resume batch send

`POST /v1/batch/{id}/resume`

## Request

- Base URL: `https://api.wraps.dev`
- URL: `https://api.wraps.dev/v1/batch/{id}/resume`

## Path parameters

## Request body

- object
  - `fromChunkIndex` number: Operator override — restart from this chunkIndex with a fresh cursor. Omit to use the durable heartbeat.

## Response `200`

## Other responses

- `400`: Malformed request — unparseable body or an invalid parameter.
- `401`: Missing, malformed, or revoked credentials. Send `Authorization: Bearer <api key>`.
- `403`: Authenticated, but the resource belongs to another organization.
- `404`: No such route, or no such resource in this organization.
- `422`: The request parsed but failed schema validation.
- `429`: Rate limit exceeded. Wait for the window named by the RateLimit headers.
- `500`: Unexpected server failure. Safe to retry with backoff; quote `requestId` if it persists.
