## About

## What it does
PDF Merge combines two or more uploaded PDF files into a single PDF. Send an array of binary files in `files`, and get one merged PDF back as binary output.

Use it when you need to assemble scanned pages, concatenate reports, or bundle customer documents into one download. Because the endpoint works on uploaded files directly, it fits cleanly into document workflows where PDFs arrive from forms, storage buckets, or user uploads.

PDF Merge is a straightforward file operation: the request body contains `files`, and the response is the merged PDF file. There are no extra metadata fields to map or parse, which keeps integration simple when you just need the final document.

Typical uses include consolidating invoices before archiving, joining generated statements into a packet, or creating a single attachment for sharing and storage.
