# Campaign Codes

Redemption codes are unique codes assigned to campaigns. Use this import to pre-load a pool of codes for a campaign.

**File format:** CSV

#### Sample file

{% file src="/files/DL3LJpdyBrs5KsT9JC8D" %}

{% code title="redemption-codes-import-sample.csv" %}

```csv
code
SUMMER2024-ABC123
SUMMER2024-DEF456
SUMMER2024-GHI789
```

{% endcode %}

#### Format rules

* The file **must** include the header row `code`
* Each subsequent row contains one unique redemption code
* Codes must be unique within the tenant
* No extra columns — only `code` is supported

{% hint style="info" %}
**Codes are tied to a specific campaign.** When importing, you will be asked to select the target campaign. Make sure the campaign exists before importing codes.
{% endhint %}

### Common mistakes

| Mistake                         | Fix                                                                                                                              |
| ------------------------------- | -------------------------------------------------------------------------------------------------------------------------------- |
| Missing header row              | The `code` header is required                                                                                                    |
| Duplicate codes within the file | Ensure all codes are unique                                                                                                      |
| Extra columns                   | Only `code` is supported — remove additional columns                                                                             |
| Non-UTF-8 encoding              | Re-save as UTF-8 to avoid corrupted special characters                                                                           |
| Confusing the two import types  | Redemption codes go into **campaigns**, reward coupons go into **rewards** — they are selected separately in the import dropdown |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.openloyalty.io/main-features/imports-exports/imports/sample-import-files/campaign-codes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
