This tutorial shows how to Python REST API developers can add text to a PDF using Aspose PDF Cloud. You’ll learn to write a paragraph that contains multiple lines and segments, each of which can be formatted independently. For more information about the PDF format, see the PDF file info page.

Prerequisite

• Create an account API credentials
• Download the Aspose.PDF Cloud SDK for Python
• Set up a Python project with the SDK for writing text

Steps to Edit PDF File with Python REST Interface

1. Create a PdfApi object using your API key and APP SID for adding text.
2. Build a paragraph by defining the text lines and the rectangular area where the text will appear.
3. Upload the target PDF file to Aspose Cloud storage.
4. Call the PutAddText method to write the paragraph into the PDF.
5. Download the updated PDF file that now contains the new text.

These steps illustrate how to build a PDF text editor with Python RESTful Service. First, create segments and text lines, then combine them into a paragraph. After uploading the PDF, invoke PutAddText() to insert the paragraph with multiple lines and segments.

Code to Write on PDF File with Python‑based API

The sample program demonstrates editing a PDF via the Python REST API. You can control text alignment, font, color, strike‑out, underline, subscript, superscript, margins, wrapping mode, and many other properties. Provide the page number (starting at 1) to specify where the text should be inserted.

If you need to strike through existing text in a PDF, see the article on Strike Through Text in PDF with Python REST API.
