Hi everyone
I’m building a scenario that should:
- List all PDFs in a specific Dropbox folder
- Create share links for those files
- Merge them using PDF.co
- Upload the merged PDF to Google Drive
Everything works up to a point — PDFs are found and share links are generated, and files are uploaded to Google Drive… but only one PDF at a time.
The Issue:
Even though there are multiple PDFs in Dropbox, the Create/Update Share Link module seems to process them one by one, so only a single share link gets passed to PDF.co, which ends up just pushing individual PDFs through — not merging them.
My Goal:
I want to merge all PDFs from the Dropbox folder into one file, and upload that single merged audit-ready PDF to Google Drive.
What I’ve Tried:
- Used Array Aggregator to collect the share links → didn’t solve it
- Tried Text Aggregator → no luck
- Set up the scenario to run after all files are listed
- PDF.co keeps throwing
[400] Invalid input parametersif more than one file is not correctly passed
Question:
How can I wait until all share links are ready, then send them all together to PDF.co’s “Merge a PDF” module?
Or — is there a better approach to reliably merge multiple Dropbox PDFs into one file?
Thanks in advance — any help or creative workarounds appreciated! 
Neil
