# Bulk-create child QR Codes

> POST /qr/{parent_qrid}/children/bulk/

Creates many child variants under one GS1 parent in a single call.

```
POST   https://api.scanova.io/qr/{parent_qrid}/children/bulk/
Authorization: 401f7ac837da42b97f613d789819ff93537bee6a
```

<ParamField path="parent_qrid" type="string" required>
  The `qrid` of the GS1 parent QR Code.
</ParamField>

<ParamField body="rows" type="array" required>
  Non-empty list of child-create-shaped objects — each entry takes the same `qualifiers`, `dataAttributes`, `variantLabel`, and `name` fields as [Create a child QR Code](/api-reference/management-api/qr/child-list-create#create-post).
</ParamField>

<RequestExample>
  ```bash cURL theme={null}
  curl -X POST "https://api.scanova.io/qr/Qz9y8x7w6v5u4t3s/children/bulk/" \
    -H "Authorization: 401f7ac837da42b97f613d789819ff93537bee6a" \
    -H "Content-Type: application/json" \
    -d '{
        "rows": [
            {
                "qualifiers": [
                    {
                        "id": "10",
                        "value": "LOT-2026-04"
                    }
                ],
                "variantLabel": "500ml bottle"
            },
            {
                "qualifiers": [
                    {
                        "id": "10",
                        "value": "LOT-2026-05"
                    }
                ],
                "variantLabel": "500ml bottle"
            }
        ]
    }'
  ```
</RequestExample>

Returns `201` with the created children as a list.

<Note>
  The `CHILD_QR_CODES` quota is checked for the whole batch up front, using a future limit of `len(rows) - 1`, so a batch that would exceed the plan fails before any child is created rather than part-way through.

      summary: Bulk-create child QR codes
      description: >-
        Creates many child variants in one call. `rows` is a non-empty list of
        child-create-shaped objects. The CHILD_QR_CODES quota check uses a
        future limit of len(rows) - 1, so the whole batch is validated against
        the plan before anything is created. Returns the created children as a
        list.

        Send your Management API key as the raw value of the Authorization
        header — no "Bearer " or "Token " prefix, and no other characters.
        Example: `Authorization: 401f7ac837da42b97f613d789819ff93537bee6a`. A
        header containing more than one space-separated part is rejected
        outright. Requests also require the request's Host header to be the
        management API host (e.g. api.scanova.io) — the same key sent to the
        regular API host will not authenticate.
