Walmart API multipart feed submission in ruby

walmart_multipart_feed_post_request.rb

    # Submits a feed to Walmart
    # @param feed_data [Hash] data that will be submited with the feed
    # @param type [String] Enum: "item" "RETIRE_ITEM" "MP_ITEM" "MP_WFS_ITEM" "MP_ITEM_MATCH" "MP_MAINTENANCE" "SKU_TEMPLATE_MAP" "SHIPPING_OVERRIDES" 
    def submit_feed(feed_data, type)
      # To add a param to a multipart POST request you need to append the params to the URL
      endpoint = "https://marketplace.walmartapis.com/v3/feeds?feedType=" + type
      
      headers = self.api_client.headers.with_indifferent_access 

      uri = URI(endpoint)
      request = Net::HTTP::Post.new(uri)

      # Add Required Headers
      request['Authorization'] = headers["Authorization"]
      request['WM_SEC.ACCESS_TOKEN'] = headers["WM_SEC.ACCESS_TOKEN"]
      request['WM_QOS.CORRELATION_ID'] = headers["WM_QOS.CORRELATION_ID"]
      request['WM_SVC.NAME'] = headers["WM_SVC.NAME"]
      request['Accept'] = headers["Accept"]

      # Set form wants an array of arrays, basically the first item is the key and the second the value
      request.set_form([["file", feed_data.to_s]], 'multipart/form-data')
      response = Net::HTTP.start(uri.hostname, uri.port, use_ssl: true) do |http|
        http.request(request)
      end
    end

figured out if you are sending JSON this is the correct way to do it

    # Submits a feed to Walmart
    # @param feed_data [Hash] data that will be submited with the feed
    # @param type [String] Enum: "item" "RETIRE_ITEM" "MP_ITEM" "MP_WFS_ITEM" "MP_ITEM_MATCH" "MP_MAINTENANCE" "SKU_TEMPLATE_MAP" "SHIPPING_OVERRIDES" 
    def submit_feed(feed_data, type)
      # To add a param to a multipart POST request you need to append the params to the URL
      endpoint = "https://marketplace.walmartapis.com/v3/feeds?feedType=" + type

      uri = URI.parse(endpoint)
      http = Net::HTTP.new(uri.host, uri.port)
      http.use_ssl = true
      http.post(uri.path, feed_data, self.api_client.headers)
    end
