Change in value of JSON data at receiver end

Question

I am sending post request to facebook graph api using Httparty gem.
My code is

    message_data ={
        "recipient" => {
            "id" => recipient_id
        },
        "message" => {
            "attachment" => {
                "type" => "template",
                "payload" => {
                    "template_type" => "generic",
                    "elements" => [
                        {
                            "title" => "Titilize",
                            "subtitle" => "Subtitle"
                        }
                    ]
                }
            }
        }
    } 
options ={
            "query": {access_token: @page_access_token},
            "body": message_data
        }
HTTParty.post("https://graph.facebook.com/v2.6/me/messages",options)

Httparty will send data by converting hash into json.
Problem is at the end point data is receiving differently not as i expected (maybe httparty is not parsing properly).

Someone help me with this. Thanks

What data does the endpoint expect, and what is your code that uses Httparty to send the data? — SoAwesomeMan, Jun 26 '16 at 18:43
@SoAwesomeMan i added my code to question. I don't know what endpoint is receiving because facebook is not providing data to debug. But i am sure i am sending correct data. Because i tested request with curl and it's working. — Sri Harsha, Jun 26 '16 at 18:51
Could you execute your curl command with verbose flag `-v` and provide the output? That would help me understand what you're trying to achieve with Httparty. You could remove IDs/credentials from the output. — SoAwesomeMan, Jun 26 '16 at 18:57
@rock, are you sure that "@page_access_token" is appropriately set before making the request? I guess it would be helpful if you also mention the output of HTTParty.post( ... ). — Harsh Trivedi, Jun 26 '16 at 18:58
@HarshTrivedi {"error"=>{"message"=>"(#100) Incomplete element data: title and at least one other field (image url, subtitle or buttons) is required with non-empty value", "type"=>"OAuthException", "code"=>100, "fbtrace_id"=>"DKypmESGCUq"}} — Sri Harsha, Jun 26 '16 at 19:04
@SoAwesomeMan curl -X POST -H "Content-Type: application/json" -d "{\"recipient\":{\"id\":\"1291831200828847\"},\"message\":{\"attachment\":{\"type\":\"template\",\"payload\":{\"template_type\":\"generic\",\"elements\":[{\"title\":\"Titilize\",\"subtitle\":\"Subtitle\"}]}}}}" "https://graph.facebook.com/v2.6/me/messages?access_token=access_token" — Sri Harsha, Jun 26 '16 at 19:10

Seems like you have to set the Content-Type header. There may be issues with the Hash syntax depending on your version of Ruby, so check out this open ticket: https://github.com/jnunemaker/httparty/issues/472

str = "{\"recipient\":{\"id\":\"1291831200828847\"},\"message\":{\"attachment\":{\"typ‌e\":\"template\",\"payload\":{\"template_type\":\"generic\",\"elements\":[{\"titl‌e\":\"Titilize\",\"subtitle\":\"Subtitle\"}]}}}}"

options {
  :headers => {"Content-Type" => "application/json"},
  :query => {access_token: @page_access_token},
  :body => str
}

HTTParty.post("https://graph.facebook.com/v2.6/me/messages", options)
