  • "price": Cost and currency of the item (e.g. 9.99 USD)
  • "sale_price": discounted price and currency of the item (e.g: 9.99 USD)
  • "sale_price_effective_date": Time range for your sale period, including the date, time, and time zone when your sale starts and ends. If you don't enter sale dates, any items with a sale_price remains on sale until you remove their sale price.
    Use this format, YYYY-MM-DDT23:59+00:00/YYYY-MM-DDT23:59+00:00, as follows:
  1. Type the start date as YYYY-MM-DD.
  2. Type "T" after start date.
  3. Type the start time in a 24-hour format (00:00 to 23:59), followed by the UTC time zone (-12:00 to +14:00).
  4. Type a "/" and then repeat the same format for your end date and time.

The example below uses the PST time zone (-08:00).

Example: 2020-04-30T09:30-08:00/2020-05-30T23:59-08:00

2. Delivery method and costs

Shipping costs and delivery methods are defined by Facebook. Contact Facebook to obtain the table of costs.

  • shipping

Shipping details for the item, written as: Country:Region:Service:Price.

Format the price as a number, followed by the 3-digit ISO currency code (ISO 4217 standards), with a space between cost and currency.

To use the free shipping overlay, type the price as 0.0.

Use "," to separate multiple shipping details for different regions or countries. Only people in the specified region or country will see shipping details for that region or country. You can leave out the region (keep the double "::") if your shipping details are the same for an entire country.

Example (multiple shipping details for different regions):

  • shipping_weight

Shipping weight of the item in lb, oz, g, or kg.

3. Variation values

To display products with variations, complete the following matching and exclude the parent lines from the optimized feed.

  • item_group_id

Items that are variants of a product. Provide the same item_group_id for all items that are variants. 

For example, a red Polo Shirt is a variant of Polo Shirt. Facebook maps this to the retailer_product_group_id once they get your feed. With dynamic ads, Facebook picks only one item out of the group based on the signal we receive from the pixel or app event, based on relevance or popularity.

Manage your Exclusions

  • "Parent products" if your products catalogue contains any, this channel does not want to receive parent files.
