Now click on Credentials, just below APIs option
On this page under "Public API Access" click on Create New Key Button, for now choose browser key(as at first we wanna a test it on browser), create it and leave it, as it is for now.
Now on the new tab, open Custom Search Engine page. On this page click on Create a custom search engine, button
That will lead you to create new search engine page, here give your domain name in "Sites to search" field. (If you don't have one no worries, give any thing, that have www. in the start and .com in the end)

There you are, now turn on the Image Search, (if you want to)
