Sorry, I have to ask.
How do you get the raw data for your transactions?
A lot of wallets have an option where users can copy the raw hex signed transaction out.
If you're using Electrum, click copy when you are previewing your transaction. The raw transaction will be copied to your clipboard.
For Bitcoin Core, go to Help>Debug Window> Console and type in
getrawtransaction YOURTXID
with the TXID replaced accordingly.
If you were to do it using web application,
https://chainquery.com/bitcoin-api/getrawtransaction is an example. Select 0:hex.
Else, for Blockchain.info its
https://blockchain.info/tx/YOURTXID?format=hex
