The DocumentProcessing endpoints under `/documentprocessing` convert, merge, append and inspect documents, create PDF documents, read the attachments, metadata and form fields of PDF documents and create barcodes. Documents are sent and returned as Base64 encoded strings in JSON. The .NET package `TXTextControl.DocumentServices.DocumentProcessing` calls the same endpoints (see the [DocumentProcessing namespace](https://docs.textcontrol.com/ds-server/reference/dotnet-api/txtextcontrol-documentservices-documentprocessing/llms-full.txt)).
