The ModifyBooking endpoint is only available to MOR channel partners.
When sending orderItem elements that are not RENTAL type, make sure to include the externalId of the lodging rate element that sourced them so they can be mapped back to the correct item. This should start with ORSUR (for fees and discounts) or ORTAX (for taxes):
cURL example:
curl --user ${ownerrez_user}:${ownerrez_key} --location --request POST "${ownerrez_api}/haolb/modifybooking?type=${ownerrez_user}&key=${ownerrez_key}&bookingId=${ownerrez_booking_id}" \
