title: How can I use Google Drive Files inside a WebApp (PHP, Google APIs)
body: <p>I'm currently in the process of evaluating a platform that I'll have to develop and I'm wondering how much of this is possible using already existing libraries and such.</p>
  
  <p>In short, I need to have users being able to add files to a <strong>Google Drive account</strong> created for the application (That part I've already figured out using the <strong>Google_Service_Drive API</strong> for the upload part.). Files will be either a <strong>PDF or a Powerpoint Presentation (.ppt/.pptx)</strong>. (I know that Google Drive uses Google Slides to read Powerpoint Presentation but that'll will come afterwards.)</p>
  
  <p>I need to be able to <strong>display the content uploaded by the users</strong> on that same GDrive Account. So, if the user uploaded a .ppt/.pptx (which will be converted to a Slide Presentation), I need to "embed" it on the webpage, same for the PDF (I'll have to iframe the PDF itself as far as I'm aware).</p>
  
  <p>Are those elements possible using the <strong>Google Drive API</strong> and the <strong>Google Slides API</strong>? Or would I need more than those 2 apis in order to fulfill the requirements? <strong>Or is this not possible to 'read' the GDrive files outside of GDrive itself</strong>?</p>
  
  <p>Thanks.</p>
