How to account for an empty value?

So I've got an enternal API that I'm pulling data from and because there are multiple pages of data in these calls I will need to do some pagination.

This particular API I'm working with has a field that they print in the API called 'nextCursorMark' with a value next to it. It's basically the bookmark ID to tell the next API call where to start.

When it gets to the point that we're on the final page of data, the 'nextCursorMark' value will be blank.

In my Conditional statement, I need to tell Xano that when the 'nextCursorMark' value is empty, stop looping.[image.png]My question is for that 'match' would I use the null function or would I just leave it empty? Unlike other APIs I've seen in examples, this particular API does not print anything like 'null' on that final page, it just leaves it empty.
