One of the most important aspects of managing PDF files is the efficiency and cross-platform support. You could be working on creating reports, invoices, legal documents, business proposals, or contracts; the PDF file format is at the forefront of document manipulation. The requirement to merge multiple PDFs into one cohesive document is quite common. Combining PDFs is useful for several reasons: it simplifies document management, reduces clutter, and makes sharing or printing easier. In this article, we will show you how to easily merge PDF files using the Cloud .NET SDK with only a few API calls.
Steps to Merge PDF Files using .NET REST API
- Sign up and get your API credentials from the GroupDocs Cloud Dashboard
- Install GroupDocs.Merger Cloud .NET SDK using the NuGet package
- Set up your API credentials using the Configuration class
- Initialize an object of the DocumentApi class
- Configure the source PDF documents and select pages to merge
- Apply document joining options with JoinOptions
- Create and execute the PDF merging request
The steps above make combining PDF documents in C# applications very straightforward. As a developer, you are always looking to build solutions that are efficient, scalable, and easy to implement. Merging PDFs programmatically using the cloud API offers a powerful way to streamline document management. It enables improved user experience, document organization, and process automation.

| }, | |
| // Starting & ending page number, and pages to merge | |
| StartPageNumber = 1, | |
| EndPageNumber = 4, | |
| RangeMode = JoinItem.RangeModeEnum.OddPages | |
| }; | |
| // Configure join options | |
| var joinOptions = new JoinOptions | |
| { | |
| JoinItems = new List<JoinItem> { firstFile, secondFile }, | |
| OutputPath = "merger/merged.pdf" // Output file path | |
| }; | |
| // Create a join request and perform the merge operation | |
| var joinRequest = new JoinRequest(joinOptions); | |
| var result = documentApi.Join(joinRequest); | |
| } | |
| catch (Exception ex) | |
| { | |
| Console.WriteLine("An error occurred: " + ex.Message); | |
| } | |
| } | |
| } |
