ChatGPT

Register with the channel

To get started on ChatGPT, sign up here: https://ads.openai.com/

To display your products on any channel, also check that your catalogue contains the data normally required by Lengow.

Always follow the same steps to set up a channel in Lengow, as detailed in this article.

Add a channel

Add the channel in your Lengow account.

Tip: To see all available channels, select "All countries" in the filters when choosing a channel.

We recommend defining a Segment within your catalogue to only configure and send the products you want to publish on this channel.

Map Categories

There is no "Categories" tab in this channel configuration, which means that category mapping is not provided directly by ChatGPT.

However, the "product_category" attribute is required to supply your own category taxonomy.

Complete Attributes mapping

As OpenAI specifications evolve frequently, up-to-date attribute descriptions, accepted values, and formatting rules are available directly within the Lengow platform.

Ensure mandatory fields such as "item_id", "title", "description", "url", "price", and "image_url" are mapped accurately.

1. Set up your special offers/sales

To set up special offers / sales, fill in the following fields:

• sale_price: the current, discount price of your products
• price: the regular price of your products
• sale_price_start_date: required when "sale_price" is present.
  Example: '2025-07-01'
• sale_price_end_date: required when "sale_price" is present.
  Example: '2025-07-15'

2. Delivery cost

Complete the following attributes to set your shipping options:

• "shipping": enter the shipping cost.
  Expected format: country:region:service:price (ex: 'FR:-:Standard:4.90 EUR'; 'FR:-:Express:9.90 EUR')
  Use ISO 3166 country codes (e.g., FR, ES, DE).
  Use ISO 4217 currency codes (e.g., EUR, USD).
  If no region applies, use - (dash).
  Separate multiple shipping options with ; (semicolon).

3. Variation values

To correctly display products with variations, you need to define both the variant category (name) and its specific value using the following attributes:

• "custom_variant1_category": Defines the type of variation.
  Example: 'Fit_Type'
  Rules: Free text, the naming must remain consistent across your catalogue (e.g., always use 'Fit_Type' for fit variations).
• "custom_variant1_option": Defines the value of that variation.
  Example: 'Wide'
  Rules: The value must match the declared category meaning (e.g., if the category is 'Fit_Type', the option could be 'Slim', 'Regular', or 'Wide').

Manage your Exclusions

Configure exclusions to exclude the products you don't want to publish on this channel.

Launch & Submit Feed to ChatGPT

OpenAI supports connecting a product catalogue via a publicly accessible HTTPS URL generated by Lengow.

1. Retrieve your Feed URL in Lengow

Once your channel configuration (Categories, Attributes, Exclusions) is complete, go to the "Optimisation" / "Feed URL" tab in Lengow and copy your HTTPS feed URL.

2. Add your Feed URL in OpenAI Back Office

Log in to your OpenAI Ads platform. Depending on your current setup, you can either create a new feed or update an existing one:

A. Create a new feed

1. In the left-hand navigation menu, click on Tools and select Feeds.
2. Click on Create feed and select the "Hosted URL" option as your feed source type.
3. Paste your Lengow HTTPS Feed URL into the dedicated field and save to complete the integration.

B. Update an existing feed

If your feed has already been set up and you need to update or replace your Lengow URL:

1. Go to Tools > Feeds.
2. Locate your feed in the list, then click on the three dots icon (•••) on the right-hand side.
3. Select "Edit hosted URL" from the dropdown menu.
4. Replace the existing link with your new Lengow HTTPS Feed URL and confirm your changes.
