The Challenge: Merging PDFs
As integration Medium, our tasks often involve consolidating information scattered across multiple documents. Merging PDF files is a common requirement that can be elegantly handled within MuleSoft.

In my case, I will receive multiple pdf file as API Request. I’m using org.apache.pdfbox library to achieve PDF file merging and to send back as response I set outboundHeaders values as header in http Listener.

In my case, I will receive two pdf file from postman. I need to merge that two pdf file into single pdf and send back to the user. for this case I’m reading the first and second file from input payload and trying to utilizing org.apache.pdfbox library in java as like below.
