Merge Multiple PDFs from a Folder in Make: Iterator, Array Aggregator, and PDF4me Step-by-Step
· 9 min read
You have multiple PDFs in a Dropbox folder and want them merged into a single PDF automatically. The catch: PDF4me Merge Multiple PDFs expects an array of file data, but Dropbox Watch Files returns a list of file metadata—and Download a File returns one file at a time. To bridge that gap, you need Iterator and Array Aggregator: the Iterator processes each file one by one, and the Array Aggregator collects those results into the array that Merge expects.
This guide walks through the full Make scenario, with special focus on how the Iterator and Array Aggregator work and how to wire them to the PDF4me Make connector.
