API 7-1Kola vili e le maneta mo le viliina lelei
O kola vili o tubula puipui mafiafia e gaosia mai pa u'amea malo ma gaosia i fa'amatalaga e fetaui ma / pe sili atu i fa'amatalaga API.O lo matou poto masani i mea faʻapitoa, mea faʻainisinia, togafitiga vevela, masini ma asiasiga o loʻo faʻaalia i la matou faʻatinoga o oloa.O kola vili e sau i mamanu masi'i ma fa'ata'amilo fa'atasi ma fa'aopoopoga fa'aopoopo mo galuega saogalemu ma leai ni fa'alavelave.
