If you are working with PDFs as a nodejs developer, you know the pain associated with working with them. In this post we will cover how to conveniently add bookmarks to a PDF using our REST API in just a few lines of code.

Our API will take your .pdf file and return back to you a new .pdf file with the bookmarks added. Just make sure your PDF is saved as a .pdf file and accessible at a URL that our service can ingest. For example, see this: — Ideally a file storage provider like S3 or Azure Blob Storage. See the code sample below.
