# Shopping basket and purchase information

The additional data for shopping basket and purchase information is identical. If multiple different products are to be passed, this can be done with a single or multiple requests. We recommend minimizing the amount of requests and sending multiple events with a single call.

It's not necessary to know if this action is caused by a search or not, this will be checked later in the analysis. As this tracking event does not contain any FactFinder specific data it can on principle be sent from shop code and does not need javascript.

| `price`    | essential | <p>Product price; in each instance, the unit price should be provided, even if a customer has purchased several units of the same product and/or placed them into the shopping cart.
