If this container is returned in the getActivityOptions response, the seller can use the provideTrackingInfo call to provide tracking information to the buyer. If previously provided to the other party, the carrierUsed and trackingNumber are returned as child fields, and their values can be referenced and reused in the provideTrackingInfo call, or in the Resolution Center.
The provideTrackingInfo activity option is applicable for the seller if the seller has shipped the original item, a replacement item, or missing/replacement parts to the buyer.
See the
Field Index to learn which calls use provideTrackingInfo.
