Newbie help with Pipeline copy from Web API that uses header token

I wasnt as clear as I could have been, so no worries! I can't add images sadly, but heres some instructions:

1. In your pipeline create string Variables called bearer_type and bearer_token and set the values as your "some_api_token" and "hard coded" token, respectively
2. In a copy activity for source create a HTTP source against the base URL for your API. In your example it's https://someurl.com/
3. Use Anonymous for the authentication of this connection. If this URL isnt publically pingable then this will fail and you won't be able to do this until On-Prem data gateways are enabled for data factory to use.
4. In the copy activity set the connection type to REST
5. In the Relative URL build whatever string you need. Your example would be:
   1. /api/nameofapitouse
   2. Under advanced set the request method to GET
   3. Create 1 Additional headers
   4. Header Name = Authorization
   5. Value (use dynamic content) = 

@concat(
    variables('bearer_type')
    , ' '
    ,variables('bearer_token')
    ) 

• Now setup your sink
