Api pagination-with scroll id that has to be replaced in the headers of the download tool

[Sara_Pulgarin]

Hello, I am trying to construct an API  pagination process with an iterative macro, but I am having issues because to be able to scroll I need to pass a new header.

to configure the download tool I add two headers, for the first iteration I leave the x_scrollid blank:

But for the next request I need to be able to replace the blank value with the output of the first iteration, so I created an iterative macro that outputs that x_scrollid:

I was planning to replace the value with the update value tool connected to an input macro but then it gives me an error ("input cannot be used as a question input for this action type at least one field must be selected")

is there another way to do this?

macro input is to bring your datastream in. You cannot feed it into an action tool to update a filter tool. Macro Input is looped in an iterative macro via interface designer.

Thanks, I was able to do it with an iterative macro!
