I'm attempting to access Sharadar's premium Core US Fundamentals Data from Quandl with AddData. They want an url like this:
https://www.quandl.com/api/v3/datatables/SHARADAR/SF1.csv?ticker=AAPL&api_key=1xaA2KgN-ESm-fzR3Kmy
I can indicate 'SHARADAR/SF1', but how do I include the ticker when AddData has no way of indicating what ticker to use?

Hmmm. Looks like I might be able to inherit from Quandl and override the GetSource function to hack in a change to the url. If anyone knows a proven way I'm all ears.

}Here is what I've been using to access different mutual funds data from an API, this might work for you?
Ya, that looks similar to what I'm going to attempt. Thanks!
Will // Warren -- you should also set the period for custom data so you get it at the right time.
In this case Period = TimeSpan.FromDays(1)
Otherwise its point data and Time = EndTime
