## Request parameter values

### Generic

Basic setup and customization options for scraping Kroger marketplace.

<table><thead><tr><th width="206">Parameter</th><th width="360.3333333333333">Description</th><th>Default Value</th></tr></thead><tbody><tr><td><mark style="background-color:green;"><strong>source</strong></mark></td><td>Sets the scraper.</td><td><code>kroger</code></td></tr><tr><td><mark style="background-color:green;"><strong>url</strong></mark></td><td>Direct URL (link) to any page.</td><td>-</td></tr><tr><td><code>render</code></td><td>Enables JavaScript rendering when set to <code>html</code>. <a href="../../../features/js-rendering-and-browser-control/javascript-rendering"><strong>More info</strong></a><strong>.</strong></td><td>-</td></tr><tr><td><code>callback_url</code></td><td>URL to your callback endpoint. <a href="../../../../integration-methods/push-pull#callback"><strong>More info</strong></a>.</td><td>-</td></tr><tr><td><code>user_agent_type</code></td><td>Device type and browser. The full list can be found <a href="../../../features/http-context-and-job-management/user-agent-type"><strong>here</strong></a>.</td><td><code>desktop</code></td></tr></tbody></table>

&#x20;    \- mandatory parameter

### Localization

Customize results based on store locations, delivery areas, and preferred fulfillment methods.

<table><thead><tr><th width="210">Parameter</th><th width="172.33333333333331">Description</th><th width="153">Default Value</th><th>Dependencies</th></tr></thead><tbody><tr><td><code>store_id</code></td><td>Specify a store. See the available values <a href="https://files.gitbook.com/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FzrXw45naRpCZ0Ku9AjY1%2Fuploads%2FAsihGe7hi5yfauUl2JIQ%2Fkroger_stores.csv?alt=media&#x26;token=40fcd869-1845-47c5-bf76-96e74cabf685"><strong>here</strong></a>. The ID must start with '0'.</td><td>-</td><td>Required when <code>fulfillment_type</code> is set to <code>pickup</code> or <code>in_store</code>.</td></tr><tr><td><code>delivery_zip</code></td><td>Specify delivery location ZIP code.</td><td>-</td><td>Required when <code>fulfillment_type</code> is set to <code>delivery</code>.</td></tr><tr><td><code>fulfillment_type</code></td><td>Specify order fulfillment method. Available values: <code>pickup</code>, <code>delivery</code>, <code>in_store</code>.</td><td><code>pickup</code> (if only <code>store_id</code> is provided)</td><td>Requires <code>store_id</code> for <code>pickup</code> and <code>in_store</code>, or <code>delivery_zip</code> for <code>delivery</code>.</td></tr></tbody></table>

**Dependecies explained:**

* `pickup` and `in_store` values use the `store_id` parameter to determine the correct store.
* `delivery` uses the `delivery_zip` parameter to specify the delivery location.
* If only `store_id` is provided, and `fulfillment_type` is not specified, the default type is `pickup`.

{% hint style="warning" %}
If the `fulfillment_type` and `store_id`/`delivery_zip` combination is invalid (unsupported by Kroger), the scraped page will return with a 404 status.
{% endhint %}
