# Bulk operations

> Learn how to perform bulk operations on QR Codes.

CodeQR allows you to perform bulk operations on QR Codes. This is particularly useful when you need to [create](/api-reference/endpoint/bulk-create-qrcodes), [update](/api-reference/endpoint/bulk-update-qrcodes), or [delete](/api-reference/endpoint/bulk-delete-qrcodes) multiple QR Codes at once without having to make multiple API requests.

## Bulk create QR Codes

Bulk create allows you to create up to 100 QR Codes at once.

<Warning>
  Bulk QR Code creation does not support [custom QR Code
  designs](https://codeqr.io/help/article/custom-qr-designs). Also, [webhook
  events](/concepts/webhooks/introduction) will not be triggered when using bulk
  QR Code creation.
</Warning>

<CodeGroup>
  ```bash cURL theme={null}
  curl --request POST \
    --url https://api.codeqr.io/qrcodes/bulk \
    --header 'Authorization: Bearer <token>' \
    --header 'Content-Type: application/json'
    --data '[
      {
        "url": "https://google.com"
      },
      {
        "url": "https://google.uk"
      }
    ]'
  ```
</CodeGroup>

Check out the [full API reference for the QR Code bulk creation endpoint](/api-reference/endpoint/bulk-create-qrcodes).

## Bulk update QR Codes

Bulk update allows you to modify up to 100 QR Codes simultaneously **with the same data**.

Some potential use cases:

* Tagging multiple QR Codes at once
* Setting the same expiration date for multiple QR Codes
* Updating UTM parameters for multiple QR Codes

<Warning>
  You cannot update the domain or key of a QR Code with this endpoint. Also,
  [webhook events](/concepts/webhooks/introduction) will not be triggered when
  using bulk QR Code updates.
</Warning>

<CodeGroup>
  ```bash cURL theme={null}
  curl --request PATCH \
    --url https://api.codeqr.io/qrcodes/bulk \
    --header 'Authorization: Bearer <token>' \
    --header 'Content-Type: application/json' \
    --data '{"qrcode_ids": ["clux0rgak00011...", "clux0rgak00022..."], "data": {"utm_source": "facebook", "utm_medium": "cpc"}}'
  ```
</CodeGroup>

## Bulk delete QR Codes

With bulk delete, you can delete up to 100 QR Codes at once.

<Warning>
  This is a destructive action and cannot be undone. Proceed with caution. Also,
  [webhook events](/concepts/webhooks/introduction) will not be triggered when
  using this endpoint.
</Warning>

<CodeGroup>
  ```bash cURL theme={null}
  curl --request DELETE \
    --url https://api.codeqr.io/qrcodes/bulk?qrcodeIds=clux0rgak00011... \
    --header 'Authorization: Bearer <token>' \
    --header 'Content-Type: application/json'
  ```
