I can not understand why API documentation is so hard to follow. Please give full examples of usage. It is not helpful when you have bit-and-pieces of the API and nothing is connected so that a real-world application can be made out of the dis-connect. Give full HTML or PHP or whatever code it is in so that I am not looking at the page and not having a clue as to what to do next. I clicked on something that said “Test Endpoint” and it did NOTHING. So now I do not know what to do next to get a callback into my website. I see no working examples of your APIs. I trust they work and that there are people using them but it does me absolutely no good if I can not put all the pieces in one format to run the API. Google Developers has an example of what I need. They have a tab that you can click on and it shows you the full working code with any dependencies you may need. I need a full example or end-product in order to use your products.
