This guide shows how to Python developers can automatically insert pdf page numbers using the Aspose PDF Cloud REST API and the official Python SDK, with simple code that uploads a document, applies a page‑number stamp, and downloads the updated file. For more details on the PDF format, see the PDF file information page.

Prerequisite

• Create an account and obtain API credentials to add page numbers in PDF
• Download the Aspose.PDF Cloud SDK for Python
• Set up a Python project and install the SDK (e.g., pip install aspose-pdf-cloud)

Steps to Add Page No to PDF using Python REST Interface

1. Initialize the PdfApi client with client_id and client_secret.
2. Define the input_pdf and output_pdf file names that will be used in the workflow.
3. Read the local PDF file and upload it to Aspose Cloud storage.
4. Create a PageNumberStamp object and configure its margins, alignment, and starting number.
5. Call the post_document_page_number_stamps method to apply the numbering to all pages.
6. Download the modified PDF from cloud storage and save it locally.

These steps illustrate how to insert page numbers in a PDF using the Python RESTful service. After uploading the source PDF, you create a PageNumberStamp, set its properties, invoke post_document_page_number_stamps, and finally retrieve the updated document.

Code to Insert Page Number in PDF using Python-based API

The sample demonstrates the complete flow for adding page numbers with the Python Low‑Code API. You can also adjust other stamp attributes such as opacity, rotation (0, 90, 180, 270 degrees), and indentation to meet your design requirements.
