curl to Ruby request for connecting to wheniwork - ruby-on-rails

Question

Back story
I've spent a few days on the Ruby gem for wheniwork, and it's been a nightmare. To make a long story short, the gem had a dependency of an older version of activesupport and I basically forked their repo and made a compatible version for my ruby project. I was able to create a new gem and attempted to use it, but I was getting the following json message:
{"error"=>"User login required for this resource.", "code"=>1000}
The username, password, and api key were set. What I basically need to do is access our account on wheniwork, and retrieve data.
This is an example using the curl command
curl https://api.wheniwork.com/2/login \
--data '{"username":"user#example.com","password":"*******"}' \
-H "W-Key: iworksoharditsnotfunny"
Essentially, I would get some kind of return object from wheniwork that would contain the token. I'd use this token for future requests to the wheniwork site.
To (Ruby)
A new attempt to translate this to Ruby
require 'net/http'
data = {'credentials' => {'username' => 'XXXXX#XXXXX.com','password' => 'XXXXX', 'W-Key' => '111111111XXXXX'}}
uri = URI.parse("https://api.wheniwork.com/2/login/")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
request = Net::HTTP::Post.new(uri.path, initheader = {'Content-Type' =>'application/json'})
request.add_field('Content-Type', 'application/json')
request.body = data.to_json
response = http.request(request)
Result:
#<Net::HTTPUnauthorized 401 Unauthorized readbody=true>
If you have any idea or clue (or basically anything that would help me here), I would appreciate it beyond words. Thanks!

Got it!! The major issue(s) were that the api key and (username+password) combo are two separate pieces.
I was so close the entire time, but here it is:
data = {'username' => 'XXXX#XXXXXXX.com','password' => 'XXXXX'}
uri = URI.parse("https://api.wheniwork.com/2/login/")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
request = Net::HTTP::Post.new(uri.path)
request.add_field('W-Key', 'XXXXXXXXXXXXX')
request.body = data.to_json
response = http.request(request)
puts JSON.parse(response.body)
