Shorten a long URL. POST request to: /api/v1/shorten Long URLs should be URL-encoded. You can not include a longUrl in the request that has &, ?, #, or other reserved parameters without first encoding it. Long URLs should not contain spaces: any longUrl with spaces will be rejected. All spaces should be either percent encoded %20 or plus encoded +. Note that tabs, newlines and trailing spaces are all indications of errors. Please remember to strip leading and trailing whitespace from any user input before shortening.
