Hi experts,
We are using SP 2016 and we created several document libraries to which users can upload pptx files. However we have a requirement on the files uploaded by users. We provided a template pptx file which contains a special master slides, users have to use this template to create their own files and upload. So the question is, when users upload their files, how can we check if the file is using the master template or not? Is it possible to do the checking by some REST API or JavaScript in the frontend?
Thanks,
Michael
