Generics - A simple generic API request
DECLARE @MyQuery NVARCHAR(MAX) = 'SELECT *
FROM generic_request
WITH (Url=''/groups'',
Filter=''$.value[*]'')
/*
EXPLANATION:
- This configuration calls Power BI REST API "Get Groups" endpoint and gets the Workspaces back.
- This is achieved by "/groups" value in the "Url" parameter.
- The SQL query parameter "Filter" uses JsonPath "$.value[*]".
- This gets JSON objects from "value" array and transforms them into SQL rows.

Generics - A generic API request with URL parameter
DECLARE @MyQuery NVARCHAR(MAX) = 'SELECT *
FROM generic_request
WITH (Url=''/groups?$filter=contains(name,''''MyWorkspace'''') or name eq ''''My Blue Workspace'''''',
Filter=''$.value[*]'')
/*
EXPLANATION:
- This configuration calls Power BI REST API "Get Groups" endpoint and gets the Workspaces back.
- This is achieved by "/groups" value in the "Url" parameter.
- Workspaces are filtered on the Power BI REST API side by using the "$filter" URL parameter.
- Only those Workspaces are returned that:
> contain a string value "MyWorkspace" or
> if the Workspace name is "My Blue Workspace" (each single quote is escaped with two single quotes).
- The SQL query parameter "Filter" uses JsonPath "$.value[*]".
- This gets JSON objects from "value" array and transforms them into SQL rows.
