The AdWords API (application programming interface) lets developers build applications that interact directly with the AdWords server. With these applications, advertisers and third parties can more efficiently and creatively manage large or complex AdWords accounts.
Because implementing the AdWords API takes technical know-how and programming skills, advertisers who employ developers can achieve the best results. If you don't have these resources but still want an extra tool to help manage your account, check out AdWords Editor instead.
To learn more about the AdWords API, or to register for it, please visit the AdWords API site.
