RestClient + the 37Signals API

gistfile1.rb

def do_post(account_id, endpoint, params={})
  r = RestClient::Resource.new(
    api_url(account_id) + endpoint + ".json",
    :headers => headers
    )

  # RestClient doesn't convert the POST parameters to
  # JSON, so we have to do it manually. This was the
  # big gotcha, and why we were getting 415 Unsupported
  # Media Type as the error response.
  resp = r.post params.to_json

  JSON.parse(resp)
