Merge

Gotenberg provides the endpoint /merge for merging PDFs.

It accepts POST requests with a multipart/form-data Content-Type.

Basic

Nothing fancy here: you may send one or more PDF files and the API will merge them and return the resulting PDF file.

caution

Gotenberg merges the PDF files alphabetically.

cURL

curl --request POST \
     --url http://localhost:3000/merge \
     --header 'Content-Type: multipart/form-data' \
     --form files=@file.pdf \
     --form files=@file2.pdf \
     -o result.pdf

Go

import "github.com/thecodingmachine/gotenberg-go-client/v7"

c := &gotenberg.Client{Hostname: "http://localhost:3000"}
pdf, _ := gotenberg.NewDocumentFromPath("file.pdf", "/path/to/file")
pdf2, _ := gotenberg.NewDocumentFromPath("file2.pdf", "/path/to/file")
req := gotenberg.NewMergeRequest(pdf, pdf2)
dest := "result.pdf"
c.Store(req, dest)

PHP

use TheCodingMachine\Gotenberg\Client;

    DocumentFactory::makeFromPath('file.pdf', '/path/to/file'),
    DocumentFactory::makeFromPath('file2.pdf', '/path/to/file'),
];
$request = new MergeRequest($files);
$dest = 'result.pdf';
