Rails Peddler gem: Using Amazon MWS Feeds API for adding products to Amazon seller central store

Question

I am trying to add a product to the amazon seller account using amazon mws feeds api. I am using Ruby on Rails and peddler gem. But i couldn't find any documentation/example of how to add a new product. There's a function given to submit feed (link). But i am not sure about how to send 'feed_content' parameter. Is there any example of how to do it? I am able to make the connection:

  client = MWS::Feeds::Client.new(
  marketplace_id:        'marketplace_id',
  merchant_id:           'merchant_id',
  auth_token:            'auth_token',
  aws_access_key_id:     'aws_access_key_id',
  aws_secret_access_key: 'aws_secret_access_key'
)

Kindly share any example or any suggestions of how to add a product. Thanks in advance.

FeedContent is the actual content of the feed itself, whether XML or flat file. You also need a FeedType. Have a look at the MWS Feeds API overview to learn about the process. No matter the language or platform you use, the process is the same.

A request is going to look like this:

POST /Feeds/2009-01-01 HTTP/1.1
Content-Type: x-www-form-urlencoded
Host: mws.amazonservices.com
User-Agent: <Your User Agent Header>

?AWSAccessKeyId=0PB842ExampleN4ZTR2
&Action=SubmitFeed
&FeedType=_POST_PRODUCT_DATA_
&MWSAuthToken=amzn.mws.4ea38b7b-f563-7709-4bae-87aeaEXAMPLE
&MarketplaceIdList.Id.1=ATVExampleDER
&SellerId=A1XExample5E6
&ContentMD5Value=ExampleMd5HashOfHttpBodyAsPerRfc2616Example
&SignatureMethod=HmacSHA256
&SignatureVersion=2
&Timestamp=2009-01-26T23%3A51%3A31.315Z
&Version=2009-01-01
&Signature=SvSExamplefZpSignaturex2cs%3D

and the body, which contain the products you are adding looks like this:
