ממשק Google Street View Publish API מבוסס על HTTP ועל JSON, כך שכל לקוח HTTP סטנדרטי יכול לשלוח אליו בקשות ולנתח את התשובות.
עם זאת, ספריות הלקוח של Google API מספקות שילוב טוב יותר של שפות, אבטחה משופרת ותמיכה בשליחת קריאות שמחייבות הרשאת משתמש. ספריות הלקוח זמינות בכמה שפות תכנות. כשמשתמשים בספריות האלה, לא צריך להגדיר בקשות HTTP ולנתח את התשובות באופן ידני.
כדי להתחיל, בוחרים את שפת התכנות שבה משתמשים בפיתוח. אנחנו עדיין מוסיפים שפות.
