Basket / Items

Lets us identify the individual products in an order.

Coupon Code

Identifies sales where a customer used a discount/promo code (not one provided by Kelkoo) — separates organic demand from promotion-driven volume, and is required for accurate reporting if you run a Kelkoo coupon programme. Omit this field entirely if no code was used; don't send an empty string.

Returning Customer

One of the strongest signals we can use to identify the type of traffic sent to you — e.g. prioritising acquisition of new customers vs. re-engaging existing ones. Must be sent as the string "true"/"false", not a boolean literal.

Currency

ISO 4217 code (e.g. EUR). Needed for accurate cross-country value comparisons.

VAT Amount

Lets us normalise order value to a comparable net figure across merchants.

Shipping Cost

Some merchants include shipping in the order value, others don't — passing it separately removes the ambiguity.

Affiliation

The store, brand, or sales channel the order was made through — for example, a supplying company or a brick-and-mortar store location.

Discount Amount

Helps distinguish structurally high-value orders from promotion-driven ones.

Payment Status

Lets us tell a confirmed, paid order apart from one that isn't final yet — e.g. a "pay later"/deferred-payment order, which can go unpaid, or turn out fraudulent.

Customer Lifetime Value

An open field — pass any numeric value you consider representative of a customer's worth (total historic spend, a predicted LTV score, or simply past order count as a proxy). Even an approximate value helps us understand how valuable your returning customers are.
