# Import legacy codes

In Voucherify, you can import legacy coupon codes, for example when you migrate the codes from another tool. After a successful import, the uploaded codes will be recognized as valid and inherit the discount definition from a given campaign.

There are two ways to import codes into Voucherify:

* programmable,
* with the import tool in the Voucherify Dashboard.

## Programmable import through the API

The programmable mode supports both the JSON and CSV payloads. There are four endpoints that handle the import of:

* Generic (standalone) vouchers: [JSON](/api-reference/vouchers/import-vouchers), [CSV](/api-reference/vouchers/import-vouchers-using-csv).
* Vouchers assigned to a given campaign: [JSON](/api-reference/campaigns/import-vouchers-to-campaign), [CSV](/api-reference/campaigns/import-vouchers-to-campaign-by-csv).

<Info>
  You can upload up to 100,000 codes to a campaign, as a campaign can have up to 100,000 codes by default.

  Also, the request can include up to **10 MB** of data; this means both JSON data or a CSV file.

<Note>
  Go to [Voucherify Postman workspace](https://www.postman.com/voucherify/workspace/voucherify-s-public-workspace/) to test the import:

  * [Import generic (standalone) vouchers with JSON](https://www.postman.com/voucherify/voucherify-s-public-workspace/request/u2cln3f/import-vouchers?tab=overview)
  * [Import generic (standalone) vouchers with CSV](https://www.postman.com/voucherify/voucherify-s-public-workspace/request/z9qk64n/import-vouchers-using-csv)
  * [Import vouchers to campaign with JSON](https://www.postman.com/voucherify/voucherify-s-public-workspace/request/dci1n32/import-vouchers-to-campaign)
  * [Import vouchers to campaign with CSV](https://www.postman.com/voucherify/voucherify-s-public-workspace/request/2f3d8ef/import-vouchers-to-campaign-by-csv)
</Note>

## Dashboard import tool mode

You can also import codes as generic codes or into campaigns through [the Voucherify dashboard](https://support.voucherify.io/article/45-import-codes-and-share-them-digitally).
