PDF Merger API Sample & Demo

Here are the source code samples and demos accordingly:

PDF Merge 2 Endpoint

As mentioned above, there are 2 PDF Merger endpoints. Because of the difference in file support, we will show different source code samples for each endpoint. To demonstrate the /v1/pdf/merge2 endpoint, we will use these five (5) sample documents with different file formats. There’s a PDF file, a Word document, a Spreadsheet, a JPG, and a PNG.

PDF Merge Endpoint

The /v1/pdf/merge has the same function as PDF Merge 2 except that the file support for this endpoint is exclusively in PDF format. If all of your source files are in PDF format, we recommend that you use this endpoint, otherwise, the /v1/pdf/merge2 endpoint would work best for you. To demonstrate /v1/pdf/merge, we will use these two (2) PDF files and merge them into a single file.
