Create a Document from an Upload
When you create a document by upload, you send the file to PSPDFKit Document Engine, which will manage the entire document lifecycle.
If you prefer to not store files with PSPDFKit Document Engine, you can create a document from a URL.
Your service uploads the document to PSPDFKit Document Engine, which stores the document in the asset storage and stores the metadata in PostgreSQL.
Your service receives the document ID back, which it can use to reference the document later.
