Dynamic Nested API Calls

[michaelshparber]

Hello, 

Because of how the API is structure I am not able to pull in the data I need in one call. 

I need to get all the students' attendance, classes and grades.

So, first: "http://url/api/students"  - I get a list of all students

Then "http://url/api/[StudentID]/classes " - I get a list of classes for a specific student

Then http://url/api/[StudentID]/[ClassID]/attendance - attendance for a specific student for a specific class

And finally,  http://url/api/[StudentID]/[ClassID]/grades 

I managed to do this in Power BI with Power Query functions and it's working fine, but I need to save my data to a database, so Power BI doesn't fit.

I am new to Power Automate, but played around a bit and did quite a bit of searching.

Please help.

Hi @michaelshparber 

In Power Automate you need to use the HTTP action step for executing the API.

Once the data is returned you could store all in an array. Finally once you had all the data you could loop the array and collect all the results in one array. Finally iterate the array to push the data to your database.

If you need any further help in this please let me know.

Thanks

Thank you, that's exactly what I am looking for.

I need more details, please.

How do I loop through array, firing more API calls and gathering and adding their results?

Let's say I first call http://url/api/students API, that returns list of students

Then I need for loop and for each student call http://url/api/[StudentID]/classes API - and gather and append the results...

Then - insert to SQL.

I totally understand that this should be the logic, but how to actually implement it?

I've searched a lot, but couldn't find anything similar...

If you have links to examples or YouTube - it'll be awesome!

Thanks a lot in advance!

Michael

Hi @michaelshparber 

It's difficult to show it as an example. It would be easier I could help you via screen share.

Thanks

Hi @michaelshparber 

I am trying to do something very similar in PBI. I have gotten it to work but it takes a very long time as I have a lot of records. Can you show me an example of what you did in PBI?

Thanks in advance!
