This short tutorial shows how to PDF and Python developers can seamlessly combine multiple documents using the Aspose PDF Cloud REST API, with full support for the PDF format and easy integration into your Python projects.

Prerequisite

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

Steps to Combine PDF with Python Low Code API

1. Set API key and SID for initializing the PdfApi class object.
2. Create a MergeDocuments object and provide the list of PDF files that you want to merge.
3. Upload all the source PDF files using the UploadFile() method in the PdfApi class.
4. Call the PutMergeDocuments() method to merge all the PDF files into a single destination PDF file.
5. Download and save the output PDF file containing the contents of all the merged PDF files.

These steps summarize how to merge PDF online with the Python REST API. Use the MergeDocuments class to build the list of files, upload them with PdfApi.UploadFile(), and invoke PutMergeDocuments() to perform the merge in the cloud. After a successful response (status OK), call DownloadFile to retrieve the combined PDF.

Code to Combine PDF Files with Python-based API

The sample demonstrates how to concatenate PDF files using the Python REST interface. Ensure the filenames used in UploadFile() match those listed in the MergeDocuments object. When downloading the resulting PDF, set the Position parameter to zero; otherwise the file cannot be saved correctly.

For more information on creating an empty PDF file with the same API, see the article: Create a PDF Document with Python REST API.
