Merge PDFs: Send links for PDF files from Pipedream to PDF.co

I would like to merge two PDF files using PDF_co. I’m sending links from our database to PDF_co and receive a link to the merged file. It works great using Make but I have no idea how to implement this with Pipedream (Python). The trigger URL has several parameters: a record no. and two links. I also need to know how I can receive the link from PDF_co (which will be stored in our database or sent to the user). Who can help? Thank you.
