Merge multiple pdf files using API

Hello,
I am looking for a solution to merge multiple pdfs into a single pdf file in Salesforce.
But I want the solution to work via API through salesforce as I want to send the pdf files and want to automate the merging of the files on the go with some info as requested in such a way that the new merged pdf document can be downloaded on the button click.
Is this possible using Aspose??
Do you provide the API to merge files?

You can surely use Aspose.PDF in order to merge PDF files and send the output to browser for download. Please check below API documentation for further information:
