# sendConversion

This endpoint will record a conversion with Rejoiner.

Optional parameters may be specified to provide the cart data and cart items associated with the converted order. Although these parameters are optional, **it is highly recommended that you provide them if possible.** This will help ensure that the data Rejoiner has is accurate.
