I have been reading about nested API calls, but I can't apply it to my situation. I have two API URLs, one a parent record which gives me a list of all parent records when queried. The other is for the child records which has a mandatory parameter of ParentID.
I want to be able to first call the parent URL to find a list of all parent IDs, then dynamically call the second URL to return the records for all the children.
So
http://example.com/api/parentrecords
Parent ID | Title |
1 | Something |
2 | Something Else |
3 | Blah |
4 | Blah Blah |
Then from this list dynamicall call the child records URL based on the parent IDs
http://example.com/api/childrecords?ParentID=1
http://example.com/api/childrecords?ParentID=2
http://example.com/api/childrecords?ParentID=3
http://example.com/api/childrecords?ParentID=4
to retrieve all the child records for those parent records, which should give me something like
ID | Parent ID | Details |
10 | 4 | Blah |
11 | 1 | Something |
12 | 2 | Another Blah |
13 | 1 | Some Words Go Here |
14 | 3 | Lorem Ipsum |
15 | 3 | Mickey Mouse |
Is this possible?

Perfect, thank you 😊
I wasn't understanding the workings behind function and parameters until I watched this video - https://www.thebiccountant.com/2018/03/22/web-scraping-2-scrape-multiple-pages-power-bi-power-query/ (if this helps anyone else out in the same situations.
@nimdy you should write an M function and pass parent id as value to this function and construct API URL in this function from the parent id parameter and call the API.
In your parent table, create add a custom column and call the above function by passing parent id as parameter. That will do it.
