# Heureka - Parameters

The query parameters available to a Heureka connector.

These are the parameters a Heureka connector's query accepts. The recommended template sets the ones it needs; the rest are only reachable by editing the connector in the Advanced Editor.

Most accounts never touch these. The page exists so that when a connector does need adjusting, what is adjustable is written down. The columns it can return are listed separately on [Heureka - Supported Columns](/roivenue-resources/roivenue-training/roivenue-app/data/connectors-overview/list-of-connectors/heureka/heureka-supported-columns.md).

## Parameters

| Parameter           | Type | Default | What it does                                                                                                            |
| ------------------- | ---- | ------- | ----------------------------------------------------------------------------------------------------------------------- |
| `CategoriesCountry` | text |         | When set loads categories for given country and adds additional category-specific columns. Supported values are: CZ, SK |

{% hint style="danger" %}
A connector edited in the Advanced Editor stops receiving template updates. Roivenue ships improvements by updating the shared template a connector is built from, and only connectors still configured by that template pick those updates up. Once a connector is switched to advanced mode, its query and transformations belong to you.
