Loop through API calls until all data is downloaded/ Iterative Macro

SamZhong

Hi,

I'm using Alteryx to connect to azure devops odata using API. Since there's a page limit for each API call, I want to use a loop to call until all data is retrieved.

Here's a sample undone workflow, I haven't been able to figure out how to organize my macro.

I've circled the part where I want to do a loop: If after I call the API, there's a "$skiptoken" in the result, means there's a page break, I want to put the "$skiptoken:1234" after the original API end point (URL) and call the API again. If there isn't, then the data download is complete.

In the end I want to union all the data downloaded. 

I think I need to use Iterative Macro. I also have the macro I built attached, that doesn't work the way I want it to.

Could anyone let me know how to do this in the right way? Thank you!

Hi @SamZhong ,

The first thing you need to do in your macro is to change it to 'iterative macro' as image below.

After that, you need to configure your macro in the 'Interface Designer' tab found in Options tab.

After that, It is done! 

You only need to guarantee that your iterative output has the data needed to go back to your input and execute once again whatever you need.

Let me know if that make sense to you.

Best,
