Handling two Binary Data (PDF)

Hello guys the search function couldn’t really help me.
My problem is that i have an invoice pdf that i want to put an overlay on it with stirlingpdf.
I just can’t figure out who to handle both pdfs in the http request node.

Workflow works like this:

  • Upload PDF
  • PDF Informations insert into MySql DB
  • then i upload the pdf on my server
  • but before uploading it i want to create a new pdf with the overlay
  • the overlay is also on my server
  • trying to figure it out like that but i dont know how i can put both binary data into the http request.

Share the output returned by the last node
