Praveen is being so humble @pranavdavar , this guy is already a pro handling Google API’s 
@pranavdavar Also the process is similar for all Google API’s. You just need to get your credentials through the developer console. Same like @praveendvd did we can play through the Google products 
Just a suggestion, if you are starting totally new, you can try if there’s already existing collection is public workspace and try to fork and start with them, and you can start adding the requests for the features as per the API documentation. 
It will work, you can do it
