How to format HTTParty POST request? - ruby-on-rails

Question

I've been playing around with API calls for a project I'm working on and I'm getting a problem when I try to pass some JSON to a POST request. The call works in Postman, but I just can't figure out how to format it in Ruby. Here's my code:
require 'httparty'
require 'json'
require 'pp'
#use the HTTParty gem
include HTTParty
#base_uri 'https://app.api.com'
#set some basic things to make the call,
#apiUrl = "https://app.api.com/"
#apiUrlEnd = 'apikey=dontStealMePls'
#apiAll = "#{#apiUrl}#{#apiUrlEnd}"
#apiTest = "https://example.com"
def cc_query
HTTParty.post(#apiAll.to_s, :body => {
"header": {"ver": 1,"src_sys_type": 2,"src_sys_name": "Test","api_version": "V999"},
"command1": {"cmd": "cc_query","ref": "test123","uid": "abc01", "dsn": "abcdb612","acct_id": 7777}
})
end
def api_test
HTTParty.post(#apiTest.to_s)
end
#pp api_test()
pp cc_query()
This code gives me this error:
{"fault"=>
{"faultstring"=>"Failed to execute the ExtractVariables: Extract-Variables",
"detail"=>{"errorcode"=>"steps.extractvariables.ExecutionFailed"}}}
I know that error because I would get it if I tried to make a call without any JSON in the body of the call (through Postman). So from that I assume that my code above is not passing any JSON when making an API call. Am I formatting my JSON incorrectly? Am I even formatting the .post call correctly? Any help is appreciated! :)
the api_test() method just makes a POSt call to example.com and it works (saving my sanity).

Just use HTTParty as a mixin instead in a class instead:
require 'httparty'
class MyApiClient
include HTTParty
base_uri 'https://app.api.com'
format :json
attr_accessor :api_key
def initalize(api_key:, **options)
#api_key = api_key
#options = options
end
def cc_query
self.class.post('/',
body: {
header: {
ver: 1,
src_sys_type: 2,
src_sys_name: 'Test',
api_version: 'V999'
},
command1: {
cmd: 'cc_query',
ref: 'test123',
uid: 'abc01',
dsn: 'abcdb612',
acct_id: 7777
}
},
query: {
api_key: api_key
}
)
end
end
Example usage:
MyApiClient.new(api_key: 'xxxxxxxx').cc_query
When you use format :json HTTParty will automatically set the content type and handle JSON encoding and decoding. I'm guessing thats where you failed.
