is useSWRInfinite / getKey reactive?

[ap1969]

Hi all,
Something's puzzling me - my API is being called when a parameter used in the API is updated:

const getKey = (pageIndex, previousPageData) => {
    if (previousPageData?.data && !previousPageData.data.length) return null; // reached the end

    let url = `/notifications?page=${pageIndex + 1}&limit=${PAGE_SIZE}&clientId=${filterClientId}&searchTerm=${filterSearchTerm}`; 
    return url;
  };

So when filterClientId or filterSearchTerm changes, the API is refreshed appropriately. But I can't find anywhere where I'm triggering the refresh.

Is getkey reactive (ie, it runs automatically when the variables change)?

Just answered by own question: I added a setTimeout function to update one of those variables long after that app has reached a stable state after restarting, and yes, the API is then called again.

That's impressive. And very very handy.
