I am new to this API and I'm facing a lot of difficulties understanding some concepts, I am building a web application similar to adstage and want to make users able to link to their Adwords accounts through my web application, but I don't understand how to do it, with the googleads library or google apiclient library? this is the first problem. can someone help me please? second problem is that I found that the
developer.google explains the steps of building the web application using only java language but what i want is the php language instead so is there anyway to translate the steps they wrote into php?
