Answer 1

It is a good idea to send

conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("CustomHeader", token);

// Set Headers
conn.setRequestProperty("CustomHeader", "someValue");
conn.setRequestProperty("accept", "application/json");

Both the type value and header should be changed. it works in my case.
