PDF Merge via Python REST API

Merging multiple PDFs into a single document on the fly can quickly become a headache when you have to juggle file streams, preserve page order, and handle varying PDF versions. The Python standard libraries don't offer a straightforward way to concatenate PDFs without pulling in heavyweight dependencies. Moreover, managing temporary files on a serverless environment adds latency and storage concerns. Existing open‑source tools often require local installation and manual handling of binary data, which defeats the purpose of a clean, cloud‑first workflow. GroupDocs.Merger Cloud SDK for Python wraps this complexity behind a simple REST interface, letting you post a list of PDF URLs or base64 payloads and receive a merged file in seconds. The SDK handles version compatibility, page ordering, and stream management on the backend, so your code stays lightweight. Authentication is handled via API keys, and the service scales automatically, removing the need to provision additional servers. W
