Combine HTML to PDF using Go REST API

Easily merge HTML to PDF format in Go code. This Go library is designed to combine multiple HTML files into a single PDF file using the REST API, i.e. by passing HTTPS calls over the Internet.

This is a professional Cloud-native HTML to PDF merging solution that provides Go programmers with both great development flexibility and powerful features. Joining HTML files together is often used when it is necessary to create a set of PDF documents of the same structure, each of which contains unique data. By merging files, you can automate your digital HTML/PDF workflows and offload some routine parts of the process to fast and efficient document-processing Go software.

Merge several HTML into one PDF in Go

You may need to combine HTML files into a single PDF file in many cases. For example, you may want to combine multiple HTML files together before printing or archiving.

HTML merging can be part of a whole integrated document-processing approach for generating PDF documents from disparate data sources. Such tasks involve the use of a full-featured HTML/PDF manipulation Go library that will process a set of HTML files and merge them together in the shortest possible time, producing a compact and accurate PDF result.

mergeDocument := models.DocumentEntry{
    FileReference: models.CreateRemoteFileReference("Input2.html"),
    ImportFormatMode: ToStringPointer("KeepSourceFormatting"),

documentEntries := []models.DocumentEntry{ mergeDocument, }
documentList := models.DocumentEntryList{ DocumentEntries: documentEntries, }
