Power Bi Data Connector Project - Loop through Multiple Sources

[flow]

Hello,

I've building a Custom Data Connector. I call a website which returns a Json-list with links.
Foreach of those links i need tot get the content en make it a table.

I can't figure out how to do that... 
This is what i got so far:

 list= Table.FromList(Json.Document(Web.Contents("http://example/getlist"))),

This is what i need:

each item in list
Table.FromList(Json.Document(Web.Contents(item)))

@flow,

You can define source parameter in Power BI Desktop, there is a blog for your reference.
