Aside from the immediate code issues, what exactly is the problem you're having? I doubt this exact code would even run, but you've not properly explained what the issue is. Are you calling an API and getting an invalid response? What is the value of the API variable you're trying to use in the the path variable? Is the code throwing an exception, if it is then what does the exception tell you?

To do that, you will need to access the Indian tax man, or pay for the privelige.
