Power BI: Parameterized Loading With Web.Contents()

Stacia Varga shows off Power BI automated refresh when hitting dynamically generated endpoint URLs:

There’s just one problem. I’m using the Web.Contents() function in several queries to get the JSON data from the NHL API.

Actually, the function is not the problem. It’s the way I’m using it to dynamically construct URLs so that I can iterate through lists of players or teams or whatever to retrieve the data I want.

Clearly that technique works just fine because I have data. However, when I try to schedule the refresh in the Power BI service, I get the dreaded error: “You can’t schedule refresh for this dataset because one or more sources currently don’t support refresh.”

I explained how to solve this particular problem once upon a time. For the hockey data queries, I had to use variations on that theme to get the dynamic URLs to work. To do this, I had to fix up my queries (which are actually functions) in the Query Editor by opening up the Advanced Editor and fixing the code as noted below.

Read on for her examples.  Given some of the problems she ran into, it seems like it might be a good idea to pull that data into SQL Server (or somewhere) and thereby separate data retrieval from data processing.
