title: Getting Merged documents using CONNECT API
body: <p>Currently I am using CONNECT API configured with my system. </p>
  
  <p>Whenever DocuSign Envelope moves to <strong>Completed</strong> status, a POST request is generated to my system which contains:</p>
  
  <ol>
  <li>DocuSign Envelope information</li>
  <li>DocuSign PDF bytes ( Seperate PDF documents )</li>
  <li>DocuSign certificate </li>
  </ol>
  
  <p>I selected the option [X] Include Documents in Connect API and I am able to receive the PDF bytes.
  Currently I am using <strong>PDFTK</strong> to merge all the documents into one. </p>
  
  <p>But is there a way using Connect API to get all the Documents merged together as a <strong>one Single PDF document</strong> ?</p>
  
  <p>Parallely while reading through the DocuSign REST API guide I came across /envelope/id?merge=true which would give me the required single PDF. But while digging deeper I came to know there is a concept called <strong>Integrator Key</strong> for each implementation, which would require a DocuSign Certification. </p>
  
  <p>Inorder to just get a merged document instead of seperate PDF documents should I go through this certification process or is there a simple way to do the same ?</p>
  
  <p>If Certification is Mandatory then what kind of certification would this fall in, because I have no front end application for signing process and I am just consuming the customer generated documents.</p>
