Ka hangaia e ZC te whānuitanga o nga paipa o te raina pai o te API, tae atu ki te hunga kaha, he uaua, he uaua, he wai nui, he wai hohonu me te kawa.
Te tono o te paipa raina
E whakamahia ana nga putorino raina mo te kawe i nga momo rere, tae atu ki te hinu, ki te wai, i runga i nga tawhiti o nga paipa, e mahi ana i nga tono a Onshoul me nga tono i nga rohe o Onshoul me nga tono o Onshous me nga Taha.
