Concatenate multiple pdf files into single pdf file..

Request to concatenate a list of Pdf documents to a single Pdf document.

When setting the Accept-header in the request to "application/json" the content of the pdf file will be return as Base64 encoded string. Note that converting data to Base64 encoded strings increases the response size with approximately 33%, if you can accept the a binary format it's better to use Accept-header "application/pdf".
