Hi all I am a new coder and am looking to practise writing specific accurate code. I am not interested in uploading code for public use unless it is something that I can not find and it would be finished and completely working. I was wondering what language I would need to write in for the API. I would also like to know how to write my own code within the API as my sandbox does not seem to work unless i am adding prewritten code. Any help would be great.
