Append PDF with Python REST API

PDF and Python developers can now easily concatenate PDF documents using the Aspose PDF Cloud REST API. This short tutorial shows how to append an entire PDF or a specific page range to another PDF directly from a Python application with the official Aspose PDF Cloud SDK for Python.

Prerequisite

  • Set up a Python project and add the SDK as a dependency to enable PDF appending operations

Steps to Append PDF Documents with Python Low Code API

  1. Configure the client ID and client secret in the PdfApi instance.
  2. Load the target PDF file and the source PDF file that you want to append.
  3. Call the PostAppendDocument() method to merge the source PDF into the target PDF.
  4. Specify the start and end page numbers of the source PDF (use 0 for both to append the whole document).
  5. Download the resulting PDF that now contains the appended pages and save it locally.

These steps illustrate how to append PDF files with Python REST Interface: load the two PDFs, set the desired page range, invoke PostAppendDocument(), and store the combined file on disk.

Code to Append PDF to PDF with Python REST API

The sample demonstrates how the PostAppendDocument() method receives the target PDF as the first argument and the source PDF (the one to be appended) as the second argument. Omitting the start/end page values—or setting both to 0—results in the complete source PDF being appended.

If you need to split a PDF instead, see the related guide: Split PDF Document with Python REST API.
