Merge several attachments & download them in a single a base64 represented PDF file.
Be sure to use the attachment id, not the request id
NEW files response attribute
We recently added a new files property which allow you to loop though all attachments uploaded in the Penbox form without having to maintain an exhaustive mapping of all the data keys form by form.
The advantage of looping through files instead of the previous attachments property is that it's groupped by data key which allows you to download all files uploaded for one question in the Penbox form into a single merged PDF.
