# Send your product feed from Lengow
> Create a Lemrock feed in Lengow with My Custom Channel and send us its URL.
If your catalog is in Lengow, create a feed for Lemrock with the **My Custom Channel** app. Lengow gives you a feed URL: send it to your Lemrock contact. Your Lengow catalog isn't changed.
This guide covers the product feed. Send the [category file](/en/catalog/feeds#category-file) separately.
## 1. Create the Lemrock structure
In Lengow, go to **App > My Custom Channel** and click **Add a new channel**.
**Presentation**: name the structure `Lemrock` and pick your catalog's country.
**Format**: choose **CSV** and the **,** delimiter. Under **Quote protection for values**, choose **Add quote on values that contains the delimiter**.
**Fields**: click **import them** and import the file below, saved as `lemrock-fields.csv`. Choose the **comma** delimiter and **none** for quotes.
```csv lemrock-fields.csv theme={null}
id,required,Product ID
title,required,Product name
description,required,Plain text description
link,required,Product page URL
image_link,required,Main image URL
price,required,Regular price as 799.00 EUR
availability,required,in_stock / out_of_stock / preorder / backorder
brand,required,Brand
product_type,optional,Category on your site
sale_price,optional,Sale price as 649.00 EUR
gtin,optional,EAN barcode
mpn,optional,Manufacturer reference
item_group_id,optional,Parent product ID
additional_image_link,optional,Other images
color,optional,Colour
material,optional,Main material
size,optional,Size
product_length,optional,Length with unit
product_width,optional,Width with unit
product_height,optional,Height with unit
product_weight,optional,Weight with unit
```
What each field should contain is described in [Product feed](/en/catalog/feeds#fields).
**Settings**: don't select a tracking field, Lemrock adds its own parameters. Under **Sending options**, choose **Export via URL**.
**Categories**: add nothing. Click **Launch**.
## 2. Create the feed from your catalog
Click **Use your new channel** and select the catalog that holds your products.
In the feed's **Settings**, under **Which products do you wish to send?**, keep **All my products**, or pick a segment to send only part of your catalog. Segments are created in **Catalogues > your catalog > Segments**.
## 3. Map your fields
In **Map your product attributes**, type `$` in each Lemrock field and pick the matching field from your catalog.
A few fields need more than a direct mapping:
* **`price` and `sale_price`**: Lemrock expects `799.00 EUR`. If your field only holds the number, write `$PRICE EUR`, replacing `PRICE` with your field name.
* **`availability`**: Lemrock expects `in_stock`, `out_of_stock`, `preorder` or `backorder`. If your values differ, click the cog to the right of the field to create a **Convert values** rule, and link each of your values to one of the four.
If you only have a stock quantity, create two **Define a value** rules instead: `in_stock` when the quantity is above 0, `out_of_stock` otherwise.
* **`item_group_id`**: map the parent product ID. If your catalog has parent rows that can't be bought, remove them in **Exclusions**.
* **`id`**: use the same ID as your [conversion tracking](/en/conversion-tracking/overview).
## 4. Check and launch
Open **Preview** and check a few products:
* the 8 required fields are filled;
* prices look like `799.00 EUR`;
* `availability` holds one of the four expected values;
* product and image links start with `https://`.
Then click **Launch**.
## 5. Send the URL to Lemrock
At the bottom of the feed's **Settings**, click **Copy link**. It's also under **More actions > Copy this feed link** on the feed's page.
Send this URL to your Lemrock contact. Lemrock downloads it regularly: keep the feed active and your Lengow catalog up to date.
